A New Process for Cobalt Nickel Separation

excellent cobalt-nickel separation primary leach liquor by Cyanex 272. However, manganese extraction from the leach liquor along with cobalt could not be avoided, thus increasing the cost of the process. For sulphide ores, there is another alternative; if the ore can be concentrated by flotation, matte smelting is used instead of leaching.

The beneficiation process of nickel ore,copper-nickel separation

Nickel ore is mainly divided into copper-nickel sulfide ore and nickel oxide ore, and their beneficiation and processing methods are completely different. The main method for beneficiation of copper-nickel sulfide ore is flotation, while magnetic separation and gravity separation are usually auxiliary beneficiation methods .

Metal Profile of Nickel

The separation process for nickel is highly dependent upon the type of ore. Nickel sulfides, such as those found in the Canadian Shield and Siberia, are generally found deep underground, making them labor intensive and expensive to extract. However, the separation process for these ores is much cheaper than for the lateritic variety, such as ...
