separation process for nickel ore

Separation and recovery of iron and nickel from low-grade

Nov 01, 2020· Two key issues for low recovery of nickel by the above process is that metallic nickel disperses in the ore and unreduced Ni 2+ are incorporated into the fayalite structure as substitutes. Therefore, the metallic reduction roasting process followed by magnetic separation provide an effectively method for laterite ores.

Nickel Metal: It's Properties, History, Production & Uses

Jul 28, 2019· 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
