Flotation Machines Mineral Processing Machine

Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important appliion 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.

Talk:Copper concentrate Wikipedia

There have been examples where froth flotation was used to concentrate malachite. In general froth flotation is not used to concentrate copper oxide ores, as the cost of leaching is cheap when compared to the cost of grinding and flotation. Secondary sulfides are resistent to sulfuric leaching, and so can be termed refractory.
