Industrial Process Description

 · The air bubbles attach themselves to the copper minerals and are then skimmed off the top of the flotation cells. The concentrate contains between 20 and 30% copper. The "tailings," or gangue minerals, from the ore fall to the bottom of the cells and are removed, dewatered by "thickeners," and transported as slurry to a tailings pond for disposal.

Copper Ore Leaching Process

 · The main copper ore leaching process is flotation technology in the industrial production. Generally, copper ore has a series of characteristics, including high oxidation rate, high binding rate, large mud content, fine and asymmetry dissemination size, etc. According to different collectors, copper separation process can be divided into the following types.
