Galena - Sphalerite Flotation Separation Method

2016-4-23  The tailing of the lead flotation stage passes direct, or, as explained above, through a thickener, to the zinc conditioner, where copper sulphate is added to activate the zinc minerals. Lime is generally introduced at this point to depress pyrite and to maintain the alkalinity of the pulp at the required pH value, usually between 8.0 and 9.0.

Geoenvironmental Characterization of Sulfide Mine

2019-3-5  Spain has a long mining tradition dating from pre-historic times up to the present day. The cessation of mining activity has generated a large amount of mine wastes, most of which represent geochemical hazards. Mine tailings are watery sludge composed of medium-to-fine-grained material, resulting from grinding and mineral processing (e.g., galena, pyrite, sphalerite, and arsenopyrite).
