The chemistry of galena flotation: Principles

1994-5-1  Galena flotation also shows a marked dependence on Eh, a point all too often overlooked in extant texts [e.g. 4]. The flotation of galena from an ore in the presence of ethyl xanthate is shown in Figure 3 [18], where the ore has been ground in a cast iron ball mill.

Fundamental Flotation Behaviors of Chalcopyrite and

Copper and lead are two important and widely used metals in industry. Chalcopyrite (CuFeS2) is associated with galena (PbS) in ore, and it has been a research hotspot in separating galena from chalcopyrite by flotation. In this study, the flotation behaviors of chalcopyrite and galena were studied through flotation tests, adsorption measurements, solution chemistry calculation, Fourier ...

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.
