At the Wiluna mine, the gold ore was floated at a slightly elevated pH of 8.2 using copper sulfate, PAX, and Interfroth 50. A unit flotation cell was included in the milling circuit at the Beaconsfield mine. Copper sulfate was added to the mill, while SIBX was distributed to three different locations in the flotation circuit.
production of gold, shortening the process and increasing production efficiency. Therefore, it is necessary to consider some new flotation processes to improve the purification process of low-grade gold ore.
