flotation separation examples

Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out This method of froth floatation is a method of mineral processing in which different minerals are separated selectively Examples Carboxylates Oxyhydryls also known as soaps Examples of carboxylates are salts of
