MINING AND PROCESSING : The mining methods differ with respect to the type of ore being mined. Since nickel is composed in two types of ores, both of them are mined differently. The sulfide ores are mined using underground mining methods though open-pit mining can also be done in early stages. The laterite ores are mined through applying earth-moving operation techniques.

Extraction of Nickel Nickel Ore Mining Mining ...

The extraction of nickel process generally consists of crushing, sieving, washing, re-selection, grinding, and slurry concentration, or the nickel leaching method. The target element nickel distribution varies with the nature of the ore, mostly contained in fine-grained grades. For example, the nickel minerals of the Ramu laterite mine in Papua New Guinea are mainly enriched in fine mud of -53

Nickel processing - Extraction and refining Britannica

Nickel requires higher smelting temperatures (in the range of 1,350 °C [2,460 °F]) in order to produce an artificial nickel-iron sulfide known as matte, which contains 25 to 45 percent nickel. In the next step, iron in the matte is converted to an oxide, which combines with a silica flux to form a slag. This is done in a rotating converter of the type used in copper production. The slag is drawn off, leaving a matte of 70

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. This procedure removes the sulphides to obtain nickel (II) sulfate and cobalt (II)

This process was patented by Ludwig Mond and has been in industrial use since before the beginning of the 20th century. In the process, nickel is reacted with carbon monoxide at around 40–80 °C to form nickel carbonyl in the presence of a sulfur catalyst. Iron gives iron pentacarbonyl, too, but this reaction is slow. If necessary, the nickel may be separated by distillation. Dicobalt octacarbonyl is also formed in nickel
