Learn More· Rock gold ores have a more complex composition than placer gold ores', thus whether to choose gravity separation and flotation separation depends on the specific composition. The gold mining equipment in the beneficiation stage: magnetic separator, spiral classifier, flotation machine, shaking table.
Learn More· Flotation of copper–gold ores. For the bulk flotation of copper minerals and gold from supergene copper ores, it is normal practice to add a xanthate as the primary collector and dithiophosphate as a secondary collector (Bulatovic, 1997). This combination gives satisfactory results in respect of copper concentrate grade and copper and gold

Learn MoreFlotation of Low Sulde-containing Gold Ores The beneRciation of this ore type usually involves a combination of gravity concentration, cyanidation and Sotation. For an ore with coarse gold, gold is often recovered by gravity and Sotation, followed by cyanidation of the reground Sotation concentrate. In some cases, Sotation is also conducted on the cyani-dation tailing. The
