Diagnosis and Optimization of Gold Ore Flotation Circuit …
For the flotation tests, a gold ore slurry was prepared with 35 wt.% solid pulp density. The prepared pulps were mixed with 70 g/t of KAX, 35 g/t of AP3477, and 40 g/t of PPG for 10 min at 1200 rpm. The tests were performed in the first cell of the rougher 1 bank (#1 Rougher 1). The flotation cell was a Denver sub-A type (, Finland).

Flotation of gold and gold-bearing ores
At the Wiluna mine, the gold ore is floated at a slightly elevated pH of 8.2 using copper sulfate, PAX and Interfroth 50. A Unit flotation cell is included in the milling circuit at the Beaconsfield mine. Copper sulfate is added to the mill while SIBX is distributed to three different locations in the flotation circuit.

The flotation of gold bearing ores — A review
Abstract. The practice of the flotation of pure gold and gold-bearing ores such as tellurides, aurostibite, kerogen, pyrite, pyrrhotite, copper-gold ores and mixed sulphides is reviewed. The factors which influence the choice of collectors, pH and Eh, are discussed as well as the application of differential flotation.

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 ...

For these tests, the copper ore had to be properly reagentized. In this case, a Xanthate (Z-6) was used in combination with dithiophosphate to activate the copper for flotation prior to the coarse flotation step. In addition, a small amount of fuel oil was used as an extender to improve the floatability of the coarse particles.
