Flotation
Flotation . The process depends upon the fact that minerals with a metallic lustre, when treated in the form of a wetted pulp, adhere to oil, while earthy minerals do not. Two distinct operations are involved; first, the separation of the metallic mineral from the gangue by means of oil; second, the extraction of the mineral from the oil.
