The Nickel Mining Process - Luminos Mining

It’s not unexpected that the mining processes for nickel differ because nickel is found in two quite different forms of ore. Although some deposits were mined using open pits in the early phases, sulfide deposits are mainly mined using underground techniques similar to copper. Laterite mining is essentially an earth-moving activity, with big shovels, draglines, The Nickel Mining Process ...

Nickel / cobalt mining extraction procedures

The ore is mixed with calcium oxide and silica, producing a slag. This makes it possible to separate silver, a mixture of materials rich in copper, nickel and cobalt and a scorifiable residue. This mixture rich in copper, nickel and cobalt is what is technically called “speiss”. Getting from this mixture to the pure metal is a complex process.

Nickel: smelting, producing-Metalpedia

Flash smelting. Flash smelting (Finnish: Liekkisulatus) is a smelting process for sulfur-containing ores including chalcopyrite. The process was developed by Outokumpu in Finland and first applied at the Harjavalta plant in 1949 for smelting copper ore. It has also been adapted for nickel and lead production.
