LEAD AND ZINC ORES: FLOTATION

ores of increasingly lower grades, as well as those which are Rne, complex mineralogically, and refrac-tory, new Sotation technology must be developed. Flotation is in fact the most common process in metallic mineral separation and is the main way for recovering such valuable metals as lead (Pb) and zinc (Zn), or copper (Cu) from ores.

How to Process Low-Grade Lead Zinc Ore by Flotation

27/04/2016· The oxidized lead minerals, of which cerussite and anglesite are the most important, can generally be concentrated by flotation after their surfaces have been coated with a film of lead sulphide by a preliminary sulphidizing treatment. Since the consumption of the sulphidizing reagent is proportional to the surface area to be attacked, it is usual, particularly with a rich ore, to table out as
