Pyrite Activation in the Lead Zinc Tailings Recovery xinhai

Most non ferrous metals are metal sulfides ores, such as lead zinc ore, copper sulfide, which often coexist with a large number of pyrites.Pyrite is the main raw material for industrial sulfuric acid, but China is a leading manufacturer and consumer of sulfuric acid, soprehensive utilization of pyrite plays an important role in lead zinc tailings recovery.

Copper activation option for a pentlanditepyrrhotite

Different sulphide ores respond differently in the prospect of copper activation to thiols for froth flotation. With the BCL Selebi Phikwe ore body, pentlanditepyrrhotitechalcopyrite co occur and there is the constraint of fine pentlandite dissemination in the pyrrhotite, so that liberation is limited. In the presence of pentlandite, pyrrhotite can even be galvanically depressed.
