Nickel: smelting, producing-Metalpedia

Nickel: smelting; Extraction and purification; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.

Nickel mined from lateritic ore is mined from various depths beneath the surface using large earth-moving equipment. The other nickel containing type of ore, sulfidic ore, is usually found in combination with copper ore and is mined underground. Nickel from lateritic ore

Oxide Nickel Ore Extraction

A second advantage is that sulfide ores often contain important amounts of other values, particularly copper, cobalt, platinum group metals, and gold and silver, and the established technology makes their recovery profitable. In contrast, the laterites cannot be significantly upgraded; a tonne of ore is a tonne of feed to the extraction process.

Nickel Extraction and Purification Mond Process

Mond Process. The Mond process, sometimes known as the carbonyl process is a technique created by Ludwig Mond in 1890 to extract and purify nickel. The process was used commercially before the end of the 19th century. It is done by converting nickel oxides (nickel combined with oxygen) into pure nickel.

Copper-Nickel Ore Processing

Hydrogen sulphide and chlorine were used to remove zinc (and residual copper) and cobalt impurities respectively. Flotation The ore was an altered basic rock containing concentrations of magmatic sulphides. The sulphide phase contained the copper and nickel values and consisted of the minerals pyrite, pyrrhotite, pentlandite and chalcopyrite.
