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.

Nickel Ore - an overview ScienceDirect Topics

The smelting of ferronickel using lean nickel ores usually starts with roasting (calcining) of the ore mixture with limestone (~one third of the ore), anthracite (~1/10 of the ore amount), and recycled dust. Roasting is carried out in rotary kilns (~3 m in diameter, ~75 m in length, with a hot zone length of 9 to 12 m in the case of lean ore .

Enhanced methods for nickel recovery from low-grade ores .

Concentrating the nickel ores usually takes place close to the mine site, and involves chemical and physical processes to crush the ore and separate the nickel-bearing and gangue minerals. Mining nickel directly is the obvious route to obtaining pure nickel, however, nickel can also be recovered as a byproduct of other metals.

NICKEL AND COBALT ORES: FLOTATION

enriching the nickel content of the ore. This is com-monly carried out by magnetic separation, Sotation, or a combinationof both after the ore is comminuted to below 200 m in size. The enrichment depends upon the degree of rejection of the other sulRde and non-sulRde gangue. The maximum grade of nickel achieved by Sotation is around 28% Ni.
