Usually speaking, Nickel and copper mineral are mixed, beneficiation nickel from the mixed mineral demand the advanced beneficiation technology, Direct selective flotation or part selective flotation processing. When the copper content is higher than the nickel content in the ore, the selective flotation can be used to flotation the copper into concentrates. The advantage of this processing is that the copper concentrates have lower nickel content. Mixing floatation process: This process is used for the ore which the copper content is lower than nickel. The copper and nickel mixed concentrate is directly smelt into high nickel matte.
Liming heavy industry designed the Nickel mineral Mixing-selective flotation processing:
The mixing flotation is used to flotation the copper and nickel. Then the copper concentrate with low nickel and the nickel concentrate with copper are selected from the mixing concentrates. After smelted, the high nickel matte can be got and then goes through the flotation.
hpc 400 hydraulic cone crusher applied for the nickel beneficiation process plant:
In order to meet the nickel beneficiation process, Liming heavy industry designed the hydraulic cone crusher hpc400 as the secondary crushing machines or third crushing machines which is widely applied for nickel beneficiation plant, of course, it is also applied for gold beneficiation plant, copper slag beneficiation plant.

It has many different advanced features as follows:
1. High crushing ratio and production efficiency.
2. Less spare part consumption and low operation cost.
3. Between-layer pressuring crushing and better finished product shape.
4. Hydraulic protection and hydraulic cavity clearing, high automatization and less stopping production and repairing time.
5. Thin oil lubrication makes the life time increased.
6. Various crushing cavity.
7. Easy maintenance and operation.
