Guide About Common Gold Extraction Process

Guide About Common Gold Extraction Process

Gold flotation process is one of the most widely used methods for treating rock gold ore, and gold-bearing sulfide ore with high floatability. Flotation process can concentrate the gold into the sulfide minerals maximally, and the tailings can be directly abandoned, so the cost of gold flotation process is relatively low. 80 percent of rock ...
