How Antimony is Processed by Flotation

2019-6-1 · The complex As-Au-Sb ore is also an important antimony resource that is predominantly mined in Hunan and other places in China. It is essential to develop an economical and environmentally friendly process for the extraction of antimony from this ore. Antimony production involves hydrometallurgy and pyrometallurgy, the latter being still dominant.

Lead and Zinc Smelting

the type of ore used as a charge. In the pyromet-allurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sin-tering, into a primary smelter. Lead concentra-tions can be 50–70%, and the sulfur content of sulfidic ores is in the range of 15–20%. Zinc con-centration is in the range of 40–60%, with sulfur
