A novel value-added utilization process for pyrite cinder

 · Pyrite cinder is a typical hazardous waste produced in sulfuric acid industry, which, however, contains a significant level of valuable metals, such as iron, copper, cobalt, etc. About 12 million tons of pyrite cinder are generated in China annually, while the utilization rate is less than 50% due to the complex relationship of various components. In this study, a process of phosphoric acid leaching was used to and

Copper Smelting Process - Furnaces Used, By-Products, and

Modern smelters use processed ore fed into a flash furnace, typically fired by oxygen which produces blister , being further processed in a converter furnace. Molten is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 99.9% purity. can be recycled indefinitely without the base metal being compromised

Pyrite Depression in Copper Flotation

The Depression in a Only Flotation circuit is simple enough. If your froth flotation system only tries to recover chalcopyrite- , you need to bring the plant’s pH up to the other side right side of the curve. The more flotation collector you have on, the higher you will need to increase that pH for effective depression. You also need to insure your
