METHOD FOR RECOVERING A COPPER SULFIDE CONCENTRATE FROM AN ORE CONTAINING AN IRON SULFIDE.

摘要

In a method for recovering a copper sulfide concentrate by froth flotation from an ore containing an iron sulfide, wet grinding of the ore with grinding media made of high chromium cast iron alloy having a chromium content of from 10 to 35 % by weight is combined with an addition of hydrogen peroxide to the conditioned mineral pulp before or during flotation in order to improve concentrate grade and recovery of copper sulfides.
