The ore from the mine contains about 2% copper. To get at the copper the first stage is crushing in huge cylindrical ball mills. Ball mills crush the ore into a fine powder. (Courtesy of Rio Tinto.) Stage 2: Froth flotation The powdered ore is mixed with a special paraffin oil which makes the copper mineral particles water repellent. It is then

Keywords: Ore, xanthate, dosage, froth flotation, concentrate 1. INTRODUCTION Copper is most commonly present in the earth's crust as copper-iron-sulfide and copper sulfide minerals such as chalcopyrite (CuFeS2), bornite (CusFeS4) and chalcocite (Cu2S). The concentration of these copper bearing minerals in an ore body is low and typical copper ores contain from % to 2% Cu in open …

Froth flotation is a selective process for separating minerals from gangue by using surfactants and wetting agents. The selective separation of the minerals makes processing complex (that is, mixed) ores economically feasible. The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement.
