The mainly process of chrome ore processing is gravity separation.Sometimes low intensity magnetic separation or high-intensity magnetic separation will be used to deal with the chrome concentrate for a second processing to improve the grade of the chrome. Also some ores treated by flotation, but the gravity separation is still the main processing way for chrome ores.

The flotation technology of copper oxide ore can be divided into direct flotation and sulfide flotation. Direct flotation refers to the direct flotation of fatty acids and their soaps, advanced xanthate and other capture agents, including fatty acids, amines, emulsions, chelating agents, etc., without pre-sulfurization of minerals.
