gold ore flotation process

Gold ore flotation process_Yantai Jinyuan Mining

For the flotation of gold ore containing single gold minerals with uniform granular size and relatively coarse particle size, a stage of grinding and flotation process is usually adopted. For gold deposits with uneven distribution of coarse and fine particles, mercury plates are usually placed in the grinding and classifying circuit before flotation or use gravity separation equipment for pre ...
