This overview identified temperature and precipitation as the main seasonality triggers for changes in flotation performance. Other triggers found in the literature included total dissolved organics, amount of ultra-violent irradiation, and bacteria activity. The temperature was more frequently reported as an impactful seasonal controller, fluctuations of which cause grade, recovery, and selectivity problems in flotation: cases of laboratory and plant practices were highlighted, with some examples of ‘chemical’ solutions to low efficiency in cold flotation pulps. This overview describes seasonal cyclicity mechanisms and temperature-dependency of operations by referring to chemical and physical aspects of flotation: reactions and reagents, ore and mineral surfaces, water, bubbles, and equipment efficiency.
