The flotation of gold-bearing ores is classified according to ore type (i.e. gold ore, gold copper ore, gold antimony ores, etc.), because the flotation methods used for the recovery of gold from different ores is vastly different. 17.2 GEOLOGY AND GENERAL MINERALOGY OF GOLD-BEARING ORES

Flotation of gold and gold-bearing ores

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 ...
