· In order to overcome the difficulty of extracting gold from gold-bearing sulfide ore by cyanide process flotation was adopted based on mineralogical analysis. Mineralogy shows that gold particles are of superfine structure and mainly enclosed by sulfide ores. Primary gold-bearing sulfide ore is fine-grained pyrite and arsenopyrite.

· Ore Concentration by Froth Flotation. Remember that only 0.67 of the ore is copper. The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and ground-up limestone) to give a basic pH pine oil (yes it comes from trees -- a by

· In this study experiments were carried out on copper ore containing gold and silver obtained from Kisecik village of Hatay which is in the south of Turkey. Analyses of original ore showed that the sample contained 4.93 Cu 0.007 Co 0.92 Zn 11.41 Fe 10.72 S 4.72 g/t Au and 12.80 g/t Ag. It was determined that gold and silver could not be reached with satisfactory yields by

· 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 recoveries.
