2012-6-1 An anaerobic–aerobic biofilter was constructed to degrade organic ore floatation reagents. Anaerobic–aerobic system could degrade xanthates and dithiophosphate efficiently. Turpentine was poorly biodegradable and impeded the performance of the biofilter. Influent pH ranged 7–9 was favorable for the biofilter to maintain reliable performances. Biodegradabilities the ore floatation reagents were

2020-1-8 The reagents utilized were depressant (sodium silicate, doses from 0.5 -2 kg/ton); collector (oleic acid, doses from 1-3 kg/ton) and pH modifier (sodium carbonate). Conditioning of the pulp with reagents was performed for 2 min for the depressant and 3 min for the collector at 2000 rpm at about 50% solids by weight. Flotation

2018-9-1 It is noteworthy that TiO 2 recovery of flotation concentrates sharply increases from 26.32% to 67.33% when the de-slime yield increases from 0% to 14.35%. It was reported that without de-sliming, the flotation of smithsonite consumes more sodium sulfide (12000 g/t) and yields a lower recovery of Zn (29.4%) than that with de-sliming operation . The results suggest that de-sliming is an effective measure to erase the reagents

The single cell flotation machine can be interconnected to a number of basic groups to form a series of flotation machines. During the flotation process, pulp will be mixed with chemical reagents and agitated. Then target ore grains will selectively attached to bubbles, float onto the surface of pulp, which will be scraped out and collected.
