Flotation Mineral Processing

Flotation is also used to remove impurities before hydrometallurgical treatment ie, carbon pre-flotation to purify low-sulfide and refractory ores for further processing. Flotation is considered to be the most cost-effective method of concentrating refined gold and is often used in conjunction with flotation andor cyanidation.

Summary of Gold Cyanidation Methods Miningpedia

There are no two same mines in the world, and proper gold cyanidation methods varies from different ore conditions. Take a gold processing plant in Tanzania as an example, the gold ore in this mining area is mainly composed of sulfide ore and oxidized ore. After the dressing test, it is determined that all-sliming cyanidation method is the core.
