Nickel Ore Mineral Processing - hotminingepc

Copper- Nickel Ore Flotation Process: A basic principle of copper-sulfide nickel ore process is that it is better to let the coppers assimilate into the nickel ore. Because it is easier to recovery cooper from the nickel concentrate. The process has a best advantage-get the copper concentrate that has a low nickel rate directly.
