Jan 01, 2010· This chapter examines cancer risk related to the mining of gold, nickel and copper. The human carcinogenicity of nickel depends upon the species of nickel, its concentration and the route of exposure.
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. Cases
Copper- Nickel Ore Flotation Process. When process copper-sulfide nickel ore, collector and frother will be used in order to better results.
