Minerals Free Full-Text Derivation of Flotation ...

Copper sulfide minerals are separated from other gangue minerals by a flotation method. Flotation utilizes the surface wettability property evaluated by a contact angle degree. Law and Zhao [ 1 ] demonstrated that the tangential angle at liquid-solid-air interface can quantitatively describe the wetting of a solid surface by a liquid.
