Nickel: smelting, producing-Metalpedia

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.

Extraction of Nickel - QS Study

Extraction of Nickel . Main ore is Pentlandite; Nickel is extracted from ores through the Mond procedure, in which nickel oxides are purified throughout several steps into pure nickel metal. It is placed with hydrogen and carbon monoxide gases at 122 degrees Fahrenheit, which converts it to impure nickel.

Copper & Nickel Solvent Extraction

Three extraction stages resulted in >99-pct extraction of nickel, substantial copper extraction, and essentially no cobalt extraction from leach liquors. A crowd stage reduced the ammonia loading on the solvent by maximizing nickel loading. Residual ammonia was removed from the loaded solvent with a pH-controlled scrub.

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.
