This study investigates the potential of a Falcon Ultra-Fine (UF) concentrator for the recovery of ultrafine scheelite particles from a weathered tailing stockpile of an historical scheelite mine, as it could represent a valuable secondary tungsten resource. The tailings are characterized by a P80 of 17.2 µm, with scheelite grains exhibiting a finer size distribution (P80 = 9.3 µm) and a high liberation degree (82 wt%). A three-stage Falcon concentration circuit was tested under varying operating conditions, including feed tank design, concentration of solids, particle size fraction, G-force and the number of treatment stages. Results showed that separation efficiency is primarily governed by the tank design and the feed particle size distribution, while variations in G-force and concentration of solids produced only minor effects. Hydrocyclone desliming to remove particles finer than 10 µm prior to concentration enhanced the separation selectivity of the Falcon-based concentration flowsheet. However, such pre-treatment of the material will require the implementation of a dedicated process to recover scheelite from the overflow to limit losses. These findings highlight the challenges of effective scheelite separation due to the fineness of these tailings.
