Nickel mining process

The Nickel Mining Process. 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

    Nickel element extraction, mining technique – flash

    The extraction from the sulfide ores is a huge process involving froth floatation, smelting and electrolysis. Firstly, the sulfide ores are crushed and ground to liberate nickel containing minerals from the waste material by floatation process where the ore is mixed with certain reagents and disturbed by mechanical devices that produce air bubbles which rise above the mixture and are collected
