STUDY ON THE ORE DRESSING EXPERIMENT OF THE WEILASITUO ZINC-COPPER DEPOSIT IN INNER MONGOLIA

The Weilasituo polymetal deposit in Inner Mongolia consists of various useful elements, of which Cu, Pb, Zn, As, Ag, W, Co etc. are valuable for comprehensive utilization. The ores belong to refractory type. With the technological processes of all-flotation for Cu-Pb-successive flotation for Zn-As(-Co)-re-flotation for W-repeated flotation(by shaking table) for W, the ore dressing conditions are tested on the pH value, types and amounts of agents. An ideal ore dressing result is achieved, which provides a technological support for the production of mine.
