Nickel processing Extraction and refining Britannica
Nickel processing Nickel processing Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel
Nickel processing Britannica
With nickel found in two radically different types of ore, it is not surprising that the mining methods differ. Sulfide deposits are usually mined by underground techniques in a manner similar to copper, although some deposits have been mined using open pits in the early stages. The mining of laterites is basically an earth-moving operation, with large shovels, draglines, or front-end loaders
Nickel Mining and Processing: Everything you Need to Know
Nickel mining occurs through extractive metallurgy, which is a material science that covers various types of ore, the washing process, concentration and separation, chemical processes and the extraction process. One of the most well-known purification processes is called the Mond Process, which is an extracting and purifying process developed by Ludwig Mond in 1899.

Ores with high levels of magnesium are treated by the Caron process: using selective reduction of the ore, and ammonia leaching. This method is more energy intensive, and produces lower metal recovery.

Nickel ore has traditionally been mined by underground methods from deeply buried sulphide deposits that are amenable to conventional concentration methods. These deposits are steadily being depleted and new world-class sulphide nickel resources are hard to find. Laterite deposits, on the other hand, are relatively plentiful and generally massive-with some containing almost a billion tons of
