Separation and recovery of iron and nickel from low-grade

Nov 01, 2020· The magnetic separation efficiency of nickel from the laterite ore was evaluated using the recovery ratio of nickel R ni using the formula: (1) R Ni = m Ni × β Ni M Ni × γ Ni × 100 % where m Ni is the mass of the magnetic product, g; β Ni is the nickel content in the magnetic product, wt.%; M Ni is the mass of the reduction product, g

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

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.
