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

Optimisation of gold recovery by selective gold flotation

Two-stage flotation (copper and pyrite rougher stages) at a p80 of 70 µm indicated that high gold (95.2%) and copper (97.4%) recovery can be achieved, but the levels of pyrite in the concentrate are also very high (49.1%).
