Froth Flotation Process
Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This is a method of mineral processing in which different minerals are separated selectively. The ores containing multiple metals, such as lead, copper and zinc, can be selectively extracted by using froth floatation.
