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.
