Oct 15, 2020· Pyrite Flotation The purpose of the pyrite flotation circuit will be to recover pyrite prior to the barite flotation circuit The zinc flotation tailings report to a conditioning tank, where sulphuric acid, copper sulphate, collector, and frother are added The slurry will be then pumped to the pyrite rougher flotation cells Pyrite Rougher

Pyrite Activation in the LeadZinc Tailings Recovery Xinhai

Most nonferrous metals are metal sulfides ores, such as leadzinc ore, copper sulfide, which often coexist with a large number of pyritesPyrite is the main raw material for industrial sulfuric acid, but China is a leading manufacturer and consumer of sulfuric acid, so the comprehensive utilization of pyrite plays an important role in leadzinc tailings recovery

LeadZinc ores

The zinc concentrate is actually the tails from this bulk separation step The flotation tailing is the zinc concentrate If the silver is associated with the galena, the silver reports to the lead concentrate While pyrite is fairly easy to depress with lime, pyrrhotite is more difficult to depress
