 · 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 ... · The copper grade decreased to about 4% and 2% in the presence of 5% and 7% talc, respectively. The copper grade also decreased to about 12%, 7%, and 2% in the presence of 10%, 20%, and 30% muscovite, respectively. This can be due to the transportation of clays to the froth phase (i.e. entrainment).
