USE POLYETHYLENEGLYCOLATE AS A DEPRESSOR OF ZINC MINERALS IN THE FLOTATION BENEFICIATION OF POLYMETALLIC ORES
Comparative studies on concentration of ores Steppe fields using a combination of depressants sphalerite and pyrite: - of sodium sulfite and zinc sulfate; - sodium sulfite, zinc sulfate, and a polymeric reagent - polyethylenepolyamine. Polyethylenepolyamine is a chemical additive series "mitoplast And". Introduction polyethyleneglycolate to the process in combination with sodium sulfite and zinc sulfate, can improve the quality of the concentrates with increasing extraction of copper, lead and zinc in reducing the consumption of the main depressors.
