Separation of Copper-Nickel by Flotation and Magnetic Methods

Nov 23, 2018 · The separation of copper and nickel is achieved by differential flotation, if the mineral grains can be liberated by grinding. Normal practice is to depress the nickel sulfides by increasing the pH of the flotation pulp to between 9 and 11 and selectively floating the copper minerals. The Duluth Gabbro Complex ores are unique in that they ...

How to Recover Cobalt and Nickel from Copper

Dec 22, 2018 · If the average particle size was less than 8 µm (as a result of prolonged grinding), the flotation-separation deteriorated due to a slimes problem. Results of these tests ranged from a nickel recovery of 60 pct at a grade of 3.8 pct Ni to 24 pct at a grade of 7.2 pct Ni.

Recovery of Valuable Metals from Nickel Smelting Slag ...

Nickel smelting slag contains valuable metals including nickel and copper. Failure to recycle these metals wastes resources, and disposal of nickel slag in stockpiles results in environmental pollution.
