Flotation Method Of Ore Separation
Separation and Purification Technology
In summary, due to the complex pulp environment of the actual ore system, the difficulty of flotation separation of copper lead sulfide ore is further increased, which means that some processing methods that have obvious effects in the study of pure mineral separation are discounted in actual ore separation.
