How is Nickel Mined - Want to Know it

Nickel is often extracted from its ore by roasting at high temperatures. In some cases this is enough to separate the nickel in other cases strong chemicals are used to separate the ore. Nickel is also refined using electro refining. In this process the ore is placed in a nickel salt solution and an electrode placed in the mixture.

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.

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 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 nickel content of laterites varies widely: at Le Nickel in New Caledonia, for example, the ore delivered to the smelter in 1900 contained 9 percent nickel; currently it contains 1 to 3 percent. Mining. With nickel found in two radically different types of ore, it is not surprising that the mining methods differ.

Nickel is an important component of "ni-cad" batteries. Biological Benefits. Nickel is a necessary trace element to many species. It interacts with iron in oxygen transport. It also stimulates the metabolism, as well as being a key metal in several plant and animal enzymes. Rats raised on a nickel-poor diet tend to develop liver damage.

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 ...
