The beneficiation process of nickel ore,copper-nickel

2020-9-24  The flotation of copper-nickel ore has the following four basic processes. Directly use priority flotation or partial priority flotation process: When the copper content in the ore is much higher than the nickel content, this process can be used to select copper into a separate concentrate.
