Flotation of Gold and Gold-Bearing Ores - ScienceDirect

2016-1-1 · 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 ...
