Copper ore processing technology development and research

Since the introduction of hydrometallurgical process for copper in the late 1980s, it has been widely used in China, especially for copper-bearing materials that cannot be effectively recovered by conventional processing methods, such as waste rock from open-pit ore stripping and low-grade copper oxide ore.

The Introduction of Placer Gold Ore Dressing Technology

When the ore particles move on the table surface, its inertia force is larger than the friction between the ore and the table surface to make sure different grade ores get separated. In the process of placer gold beneficiation, usually adopting the concentrating table to do concentration to the rough concentrate ore after roughing by chute or
