The mixing flotation process is to separate nickel ore in which copper has lower content than nickel. The mixed concentrate of copper and nickel will smelt into high grade nickel directly.
Copper nickel can be get from raw ore, then the copper concentrate with low grade nickel and the nickel concentrate with low grade copper can be separate from the mixing concentrate, and the nickel concentrate will be sent into the next stop-smelting, nickel matte can be get then separated.
When floatability differences happens to the various nickel element of the raw ore, then nickel ore can be recoveried further from tailings after the copper and nickel been mixing flotation.
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 process has a vital advantage-receive copper concentrate with low grade nickel directly.
Nickel ore beneficiation can be applied to process copper nickel ore accompanied by pyrite and other gangue or nickel oxide ore.
There is a large plant of copper-sulfide nickel ore in Jilin Provice, China. Xinhai providing perfect beneficiation process of three-stage one close crushing, stage grinding, mixing-separating flotation, three stages dehydration of nickel concentrate and two stages dehydration of copper concentrate. This process characterized by easier operation, longer flotation time, fewer concentrate flotation and process concentrate ore from different stages of separation, which can recovery nickel ore as soon as possible in the flotation process. The solution of copper-sulfide nickel ore get nickel grade of 12% of high profit.
