01/10/2014  Sulfide mine flotation tailings, especially those containing large amounts of pyrite, are major sources of acid mine drainage. Although pyrite is the main mineral of the sulfide part of such tailings, other sulfides (such as copper, zinc, lead, and mercury) also may compose of significant part of these wastes. Biooxidation of pyrite is an important acid and Fe 3+ producing process: (1) FeS 2 ...

Flotation Machine - Mining Equipment Manufacturer

12/02/2019  Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.
