  • Nickel

    The flotation of copper-nickel ores has four basic processes as follows. 1) Direct priority flotation or partial priority flotation process: when copper content in ore is much higher than nickel content, this process can be used to separate copper into a separate concentrate. The advantage of this process is that the copper concentrate with

  • Nickel Mines, Nickel Extraction Process, Nickel Recovery

    Copper- Nickel Ore Flotation Process. When process copper-sulfide nickel ore, collector and frother will be used in order to better results. A basic principle of copper-sulfide nickel ore process is that it is better to let copper assimilate into nickel ore rather than the opposite. For it is easier to recovery cooper from nickel concentrate.
