flotation process for low grade nickel ore in india

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.

      The best flotation result was for the S ore sample where nickel upgraded from 3.0% up to 4.2% (i.e. by 40%) at around 70% when HDMA was used. This is considerably better than nickel flotation grade and recovery data reported in the literature for this type of ores (i.e. saprolite) . Based on these data, the best condition to upgrade nickel in the current study was obtained by using the HDMA …
