Mining process of nickel

Nickel Ore Mining Process. Nickel ore mainly consists of copper-nickel sulfide ore and nickel oxide ore, beneficiation and processing of both methods is completely different. Copper-nickel sulfide ore beneficiation methods: The most important is the flotation. The magnetic and the gravity separation is usually secondary dressing method

    Nickel matte remains after the mining and processing of either lateritic or sulfidic ore. Using the fluid bed roasting procedure, a 95 percent pure nickel can be achieved after additional refinement. Electric cells provide for a more efficient refining process. The remaining impurities are removed from the nickel using electrical cells with

    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

    Sherritt Gordon Process. The nickel and cobalt metallurgy processes begin with an initial treatment of the mineral, re-concentrating it through crushing and flotation/gravity and obtaining a “speiss”, rich in cobalt and nickel. The process begins by adding the sulfide-associated mineral to a reactor with sulfuric acid and pressurised air

    Copper-nickel mining (also known as non-ferrous mining ) in northern Minnesota is not a new issue for the state. Copper-nickel deposits have been known to exist in northern Minnesota since the 1800s, but it was not until 1948, when deposits were discovered near Duluth, that serious interest in mining these metals developed in the region

    Encyclop dia Britannica, Inc. Various processes are used to treat nickel matte. One process is the ammonia pressure leach, in which nickel is recovered from solution using hydrogen reduction, and the sulfur is recovered as ammonium sulfate for use as fertilizer. In another, the matte may be roasted to produce high-grade nickel oxides; these are subjected to a pressure leach, and the solution is electro
