Yellow phosphorus slag (YPS) is a typical industrial solid waste, while it contains abundant silicon micronutrient required for the growth of rice. The key scientific problem to use the YPS as rice fertilizer is how to activate the slag efficiently during the phosphorite reduction smelting process. In this work, an alkaline rice fertilizer from the activated YPS was successfully prepared to use the micronutrients. Thermodynamic analyses of SiO2-CaO, SiO2-CaO-Al2O3, and SiO2-CaO-Al2O3-MgO systems were discussed to optimize the acidity for reduction smelting. Results showed that the reduction smelting followed by the water quenching process can realize the reduction of phosphorite and activation of YPS synchronously. Ternary acidity m(SiO2)/(m(CaO) + m(MgO)) of 0.92 is suitable for the reduction smelting and activation of the slag. After smelting, the molten YPS can be effectively activated by water quenching, and 78.28% P, 90.03% Ca, and 77.12% Si in the YPS are activated, which can be readily absorbed by the rice roots. Finally, high-strength granular rice fertilizers with a particle size of Φ2–4 mm were successfully prepared from the powdery nitrogen-phosphorus-potassium (NPK) and activated YPS mixture.

High-P oolitic hematite is recognised as one of the most refractory mineral resources because of the special oolitic structure. Conventional selective reduction roasting is characterised by high energy consumption and large greenhouse gas emissions. In this study, a clean utilisation of refractory high-P oolitic hematite via phase reconstruction was proposed to make the P for crop fertiliser and Fe for ferrite ceramic. Phase reconstruction indicated that the oolitic and finely disseminated structure was dramatically changed by the oxidisation roasting with Mn ore at 1100°C–1250 °C. After reconstruction, 85 wt%–90 wt% Fe and Mn were concentrated in the magnetic ferrite phase whilst 90 wt%–100 wt% P, K, Ca, Si, Mg, and Al impurities were enriched in the nonmagnetic P-bearing tailings. After separation, the separated Mn ferrite and P-bearing tailings after activation could be used as ingredients in ceramic and fertiliser production. The as-purified ferrite showed good electromagnetism performance whilst almost all nutrients in the P-bearing tailings were activated via high-temperature melting and water quenching and can thus be readily absorbed by the crop roots. Moreover, the phase reconstruction mechanism and feasible granular fertiliser preparation from P-bearing tailings were discussed. All elements in the high-P oolitic hematite were utilised without emission of greenhouse gases.

Clean and deep separation of molybdenum (Mo) and rhenium (Re) from the industrial solutions with ultra-low concentrations are extremely difficult. In current study, various low concentrations of Mo and Re are efficiently separated from the industrial solutions, including lixiviums, eluents and the waste waters, via vapidly stepwise selective coagulation and flocculation precipitation. In-situ generated metal hydroxyl coagulants in the solution have selective coagulation of series isopolymolybdates, while the cetyl-trimethyl-ammonium-bromide (CTAB) has a strong combination with rhenate. The effects of metal ion types, dosages, pH value, and reaction time on the separation behaviors of Mo and Re from the solution are systematically investigated via thermodynamic calculations, SEM-EDS, FT-IR and XPS analyses. It’s found that all the in-situ generated metal hydroxyl coagulants of Cu(II), Al(III), Fe(II) and Fe(III) have selective coagulation of Mo while the Fe(III) hydroxyl coagulant (FeHC) shows the best adsorption performance. After selective coagulation by FeHC, 99.9%Mo is separated while 95.8%Re is kept in the raffinate after filtration. Then the 98.9%Re is further recovered by CTAB flocculation precipitation. The selective coagulation mechanism of Mo and Re by the FeHC is discussed. In addition, this novel technology is applicative for the deep separation of Mo and Re from various low-concentration Mo,Re-bearing industrial solutions.

Molybdenum (Mo) is a strategic metal element, and recovery of Mo from low concentration Mo-containing solution is significant to alleviate the Mo resources shortage. In this study, the treatment of low-concentration Mo-containing solution by Fe3+ addition was investigated by batch experiment, and the effects of main parameters including molar ratio of n(Mo):n(Fe), pH value, initial concentrations, and reaction time on the recovery of Mo were studied. The results showed that Mo is precipitated rapidly, with a Mo recovery of 100% in 5 min when the pH range is 4–6 and molar ratio of n(Mo):n(Fe) is greater than 1:3, indicating the reaction between Mo and Fe readily approaches chemical equilibrium. Moreover, the initial concentration of Mo in the solution has little influence on the recovery of molybdenum. This technology has potential to be applied for the enrichment and recycling of molybdenum, while at the same time meeting the industrial discharge standard for the effluent.

Polymetallic ferruginous manganese ores contain a variety of valuable metals, it is significant to realize the efficient utilization. Spinel-type composite ferrites with strong magnetism can be prepared from the polymetallic ferruginous manganese ores, while the impurities in the ores have certain impact on the properties of the ferrites. This study was mainly concentrated on the behavior of Al during the formation process of ferrites. It has been found that during the oxidation roasting process, Al element has occupied the octahedral gap (sit B) in spinel structure of ferrites, which reduced the magnetism property of ferrite. However, SiO2 can improve the magnetism properties of Al-bearing manganese ferrites owing to that SiO2 was able to transfer Al out of B sit of spinel via the chemical driving force generated by the formation of corresponding silicates from the SiO2 and Al oxides. This work demonstrated that Al impurity can be regulated by adding SiO2.

Oily ferroalloy scraps generated from machinery honing enterprises are typical hazardous municipal materials that release benzene-series volatile organic compounds (VOC), which endanger human physical and mental health. Therefore, harmless treatment and resource reuse for these hazardous materials is urgent. In this study, the VOC emission, and pyrolysis and de-oiling behaviors of oily honing scrap was first characterized to evaluate the environmental risks. Smelting separation was then proposed to economically and eco-friendly recover valuable metals from the de-oiled ferroalloy scraps. The thermodynamics of Al2O3-SiO2 and CaO-Al2O3-SiO2 systems was calculated to optimize the slag formation. Results showed that after de-oiling and smelting with CaO addition, the hazardous VOC are removed, and the valuable metals are recovered in ferroalloy state. Under optimum conditions, a crude Fe-Mo-Cu alloy with Fe, Mo and Cu recoveries of 98.5 wt%, 97.9 wt%, and 98.4 wt% were obtained. In addition, the slag containing few toxic elements and VOC can be used for silicate cement production. Pyrolysis, de-oiling behaviors and mechanism for slagging and growth of Fe-Mo-Cu alloy during smelting were discussed via various testing techniques, and leaching toxicity of the cleaned slag was also characterized in this work. This process is also applicative to recover metals from various honing ferroalloy scraps.

High smelting temperature of phosphate ore and low activity of the slag lead to energy-extensive consumption and large solid waste generation in the yellow phosphorus industry. Micronutrient-bearing cosolvents were added to the reduction smelting process of phosphate ore to reduce the smelting temperature and increase the activity of slag in the current work. Thermodynamic analysis demonstrated that B2O3 and K2O as cosolvents can decrease the melting temperature, promote the liquid phase formation and reduce the slag viscosity. In addition, cosolvents had no unfavorable effect on the reduction volatilization of phosphate ore, and the volatilization ratio of phosphorus was > 97 wt.% at 1550°C for 1 h. In this case, the value of slag was enhanced with the addition of cosolvents, and the activation ratios of micronutrients were > 90%. Resultantly, no solid waste was generated since the activated slag can be regarded as a favorable ingredient for the crop fertilizer.

Polyhedral MnFe2O4 with multilayer structure was successfully synthesized, and the possible originating mechanism of multilayer structure was firstly determined in current study. The phase formation, morphology evolution and interface reaction of the solid-state reaction of MnO2 and Fe2O3 mixture under air and reduction atmospheres were comparatively investigated, and the microwave absorption property of polyhedral MnFe2O4 with multilayer structure were discussed via the XRD, SEM, XPS, TEM, AFM and vector network analyzer measurements. Experiment results showed that multilayer MnFe2O4 can be synthesized both in the air at 1200–1300 °C and in 4 vol%CO at 1000–1100 °C. The reduction atmosphere was favorable to the formation of multilayer structure of MnFe2O4 due to the occurrence of multilayer MnO as the intermedium. In addition, morphology evolution demonstrated that the particle size of MnO2 after reduction was decreased remarkably which was also beneficial to the formation of MnFe2O4. However, air atmosphere is unfavorable to the generation of MnFe2O4 due to the recrystallization growth of Fe2O3 to lump impeding the element diffusion. Resultantly, the required temperature for the synthesis of MnFe2O4 in air was much higher than that in 4 vol% CO. One possible mechanism for the polyhedral MnFe2O4 with multilayer structure was based on the combination of the greater growth speed of (111) plane in the cubic MnFe2O4 crystal and terrace-ledge-kink (TLK) growth model. Moreover, multilayer MnFe2O4 prepared by the solid-state reaction presented good microwave absorbing property compared with that of the ferrites synthesized via the representative wet chemistry and combined methods.

SiMn alloy is the largest consumption product in the Mn series alloys. Manganese silicates generated during the pre-treatment procedures of manganese ores are the main ingredient for SiMn alloy production. However, conventional cognition is that manganese and silicon in the silicates are respectively reduced to Mn7C3 and SiC by carbon, and then the carbides interact to form alloy. In current study, pure MnSiO3 was synthesized firstly and then a new perspective on the interface reaction and morphology evolution for the reduction of pure MnSiO3 were investigated via XRD, SEM, XPS and thermodynamics analyses. Interface reaction showed that the MnSiO3 was firstly reduced to manganese carbides and SiO2, and then the SiO2 was further reduced by the carbides to generate SiMn alloy. The intermediate product Mn7C3 played a crucial role since the reduction of SiO2 by newly born Mn7C3 preferentially conducted than the carbon reductant. Morphology evolution of the interface between C and MnSiO3 as well as thermodynamic calculations of Mn-Si-O and Mn-Si-C-O systems were minutely clarified in this work to clarify the reduction mechanism. In addition, decomposition of SiMn alloy to SiC ceramic at 1700 °C was an important inducement to illustrate the frangibility of industrial SiMn alloy product.

Pyrite cinder is a typical hazardous waste produced in sulfuric acid industry, which, however, contains a significant level of valuable metals, such as iron, copper, cobalt, etc. About 12 million tons of pyrite cinder are generated in China annually, while the utilization rate is less than 50% due to the complex relationship of various components. In this study, a process of phosphoric acid leaching was used to selectively separate and recover Cu, Co and Fe from the pyrite cinder. The effects of different leaching parameters on the recovery rate of valuable metals in phosphoric acid leaching systems were investigated. Under the optimal conditions, the results indicated that the leaching efficiency of copper and cobalt was above 82% and 99%, respectively. More than 98% of iron was transferred into insoluble FePO4·2H2O, which could be used as precursor of battery-grade electrode material after a hydrofluoric acid purification process. Cu and Co in the leaching solutions were extracted efficiently by P204.

Effect of distribution of iron concentrates between pelletized and matrix feed on the preparation of blast furnace burdens from two different kinds of fine iron concentrates (magnetite and hematite) by composite agglomeration process (CAP) was explored. It was found that when the mass ratio of iron concentrate A (magnetite) to iron concentrate B (hematite) in the mixed feed was constant, the proportion of iron concentrate A in the pelletized and matrix feed significantly affected the quality of CAP products. Particularly, as the proportion of iron concentrate A in the pelletized feed increased from 0 to 100%, the yield decreased from 82.11% to 79.19% and the tumbler index decreased from 71.33% to 68.27%. The mineralization characterization results indicated that when 100% iron concentrate A was used as the pelletized feed, the crystallization styles of the outer layer and the inner layer of the pellet were different, and a lot of pores exist around hematite and magnetite phases in the pelletized part, with the weak connection of pelletized and matrix part, resulting in poor strength of agglomeration product.

The Chinese economy is in a critical period of continuous transformation of new and old kinetic energy and economic transformation and upgrading. Copper, the second largest strategic raw material, is still central to China’s economic development. As the major producer and consumer of electrical and electronic equipment (EEE), China’s production and consumption of refined copper is the largest in the world. Thus, it is necessary to forecast the supply and demand of China’s future copper. There is a huge gap between copper production and consumption in China, the current identified copper resources cannot meet copper consumption in the next five years, thus the import of copper will be more crucial for China’s future copper industry. Due to trade frictions, restriction on imports and other reasons, the import of copper from other countries will exist a lot of uncertainties. Hence, the domestic copper waste and scraps could be the suitable secondary resource for recycling copper in China. According to the grade and value of copper scraps, establishing quality standards and optimizing the disassembly process of the domestic Cu-bearing waste & scraps, and using the suitable method are the key to recycling the domestic copper scraps.

Consolidation of the ferruginous manganese ore fines is of vital importance for manganese extraction in the smelting process. The main impurities in the Fe–Mn ores are Ca and Si constituents and they have a significant effect on the consolidation of iron and manganese oxides. In this study, characterization on the behaviors of Ca and Si constituents during the roasting process of Fe–Mn ores were investigated by thermodynamic, fusion temperatures, and phase identification analyses. The results showed that the Ca and Si constituents can decrease the fusion temperature of the MnO2–Fe2O3 binary system dramatically due to the formation of low-melting complicate silicates from the CaO, SiO2, and partial manganese and iron oxides. The high-melting solid manganese ferrites phase generated from the remaining manganese and iron oxides were bonded and solidified by the liquid phase. This provided favorable mineralization conditions for the consolidation of Fe–Mn ore.

Sodium stannate (Na2SnO3) has been successfully prepared by a novel process of roasting cassiterite concentrates and sodium carbonate (Na2CO3) under CO–CO2 atmosphere, namely soda roasting-leaching process. However, more than 22 wt. % tin of the cassiterite was not converted into Na2SnO3 and entered the leach residues. Quartz (SiO2) is the predominant gangue in the cassiterite, and phase evolution of SnO2–SiO2–Na2CO3 system roasted under CO–CO2 atmosphere was still uncertain. In this study, the effect of SiO2 in cassiterite concentrates on preparation of Na2SnO3 was clarified. The results indicated that Na8SnSi6O18 was inevitably formed when cassiterite and Na2CO3 were roasted above 775 °C under CO–CO2 atmosphere via the reaction of SnO2 + 6SiO2 + 4Na2CO3 = Na8SnSi6O18 + 4CO2, and formation of Na8SnSi6O18 would be increased with increasing roasting temperature and Si/Sn mole fraction. In addition, it was found that Na8SnSi6O18 was insoluble in the leachate at pH value range of 1–14, which, therefore, was enriched in the leach residues. The silicon content of the cassiterite concentrates should be controlled as lower as possible to obtain a higher conversion ratio of Na2SnO3.

Tin-, iron-bearing tailing is a typically hazardous solid waste in China, which contains plenty of valuable tin, iron elements and is not utilized effectively. In this study, a multistage utilization process was put forward to get the utmost out of the valuable elements (tin and iron) from the tailings, and a gradient-recovery method with three procedures was demonstrated: (1) An activated roasting followed by magnetic separation process was conducted under CO-CO2 atmosphere, tin and iron were efficiently separated during magnetic separation process, and 90.8 wt% iron was enriched in magnetic materials while tin entered into non-magnetic materials; (2) The tin-enriched non-magnetic materials were briquetted with CaCl2 and anthracite and roasted, then tin-rich dusts were collected during the chloridizing roasting process; (3) The roasted briquettes were infiltrated in melting NaNO3 to prepare NaNO3/C-PCMs by a infiltration method. Three kinds of products were obtained from the tailings by the novel process: magnetic concentrates containing 64.53 wt.% TFe, tin-rich dusts containg 52.4 wt.% TSn and NaNO3/C-PCMs for high temperature heat storage. Such a comprehensive and clean utilization method for tin-, iron-bearing tailings produced no secondary hazardous solid wastes, and had great potential for practical application.

Electrolytic manganese anodic slime (EMAS) with high contents of manganese and lead is a well-known refractory secondary resource because of its complex constituents and structure. Traditional stockpiling treatment of EMAS not only causes resource waste, but also leads to long-term environmental pollution. In this study, SO2 roasting followed by acid leaching process was put forward to extract and separate manganese and lead from the EMAS. Thermodynamic analysis showed that a coexistence area of MnSO4 and PbSO4 was present in both the roasting and leaching processes. During the roasting process, manganese and lead oxides were sulfated to MnSO4 and PbSO4 by SO2. Then, MnSO4 and PbSO4 could be separated in the following acid-leaching process owing to their different solubilities in acid solution. The leaching efficiencies of 92.5 wt.% for Mn and only 3.21 wt.% for Pb were obtained under optimal conditions. This study provides an alternative approach to utilize the EMAS.

Our research group has developed a novel process for synthesizing calcium stannate in a CO–CO2 atmosphere at lower temperature (<1000 °C). The formation behavior of calcium stannate was clarified in previous publications. In this study, the properties of CaSnO3, Ca2SnO4 and Eu-doped Ca2SnO4 synthesized under different atmospheres were further characterized. The results indicated CaSnO3 exhibited good photocatalytic performance in the degradation of Rhodamine B. As a dielectric material, Ca2SnO4 synthesized under CO–CO2 atmosphere had higher dielectric constant and lower dielectric tangent loss compared with that synthesized under air. In addition, the photoluminescence properties of Eu-doped Ca2SnO4 were close to that synthesized under air.

Lead (Pb) ions are chronically detected in soil, underground and natural water, there is a need for low-cost in situ remediation techniques. A novel mineral based magnetic adsorbent, consisting of natural vanadium, titanium-bearing magnetite particles coated by humic acid (abbr. VTM-HA), was developed for removing Pb(II) from wastewater. In this study, adsorption-desorption characteristics and mechanisms of Pb (II) on the VTM-HA adsorbent were investigated. The regeneration and reuse feasibility of the VTM-HA adsorbent were also conducted. The adsorption tests further verified that Pb(II) was removed rapidly and efficiently by the VTM-HA adsorbent. Moreover, Pb (II) adsorbed on the VTM-HA adsorbent could be easily eluted using a small amount of acidic eluent, and the desorption of Pb (II) could reach 99.3 wt% in 0.1 M HNO3 (pH = 1). After five adsorption-desorption regeneration cycles, the magnetism and Pb(II) adsorption capacity of the regenerated VTM-HA adsorbent almost kept unchanged. The results indicated that the VTM-HA adsorbent had excellent adsorption capacity and regenerative ability, which could be used as ideal adsorbents for removing Pb (II) from acid wastewater in commercial application. The mechanisms of Pb (II) adsorption and desorption were explored by FTIR, XPS analysis and DFT calculation.

There are abundant ferruginous manganese ores (abbr. Fe-Mn ores) in many parts of the world. For example, almost half of the manganese ore resources in India are ferruginous and more than 73% of the manganese ores in China belong to Fe-Mn ores with a low Mn/Fe mass ratio (<3). With the depletion of high grade manganese ore resources, the Fe-Mn ores are becoming important substitution resources for extracting manganese. In general, the production of Mn alloy from manganese ores requires that the Mn grade is more than 30% and the Mn/Fe mass ratio is greater than 5. During the production of electrolytic manganese or manganese chemical products, the issue of co-leaching of Mn and Fe complicates the purification procedure for the MnSO4 solution if Fe-Mn ores are used as raw materials. Numerous approaches are reported to realize the selective extraction and separation of Mn and Fe from the Fe-Mn ores. The extraction and separation technologies cover physical beneficiation, chemical beneficiation (hydrometallurgy and pyrometallurgy) and physico-chemical combined processes. This present work reviews the technical principles, parameters and recovery efficiencies of diverse processes on the aspect of selective extraction and separation of Mn and Fe from Fe-Mn ores. This review can provide guidance for selecting appropriate methods to exploit Fe-Mn ores or other secondary resources containing Fe and Mn oxides. The authors also put forward a new route to produce manganese ferrite materials using Fe-Mn ores as the raw materials.

Preparation of refractory materials from ferronickel slag by sintering over a broad temperature range (1200°C to 1500°C) with addition of sintered magnesia was explored. The thermodynamic calculations indicated that the amounts of newly generated high-melting-point forsterite and spinel phases increase with increasing temperature. The experimental analysis demonstrated that elevating the sintering temperature promoted conversion and crystallization of forsterite and spinel phases from the original phase of the slag, with simultaneous reduction of low-melting-point enstatite. There was also rapid growth of spinel grains from about 0.5 μm to 5 μm, which should be controlled by selecting an appropriate temperature. The results showed that, by sintering the slag at 1400°C for 3 h with addition of 20 wt.% sintered magnesia, a high-quality refractory material with refractoriness of 1680°C, bulk density of 2.93 g/cm3, apparent porosity of 1.81%, and compressive strength of 166.62 MPa was obtained.
