Flotation process - Commonwealth Industrial Gases

A typical flotation process involves the separation of the constituents of a mixed ore such as an ore containing the minerals galena (lead sulphide), sphalerite (ZnS) and pyrite (FeS 2). In a first stage, galena is floated by adding a xanthate collector (0.05-0.15 kg t-1 ore) to promote the flotation of galena.
