ABSTRACT. The extraction of nickel (Ni) from sulfide resources commences with flotation to produce a concentrate which is then smelted to produce a nickel-enriched phase called matte, and further refined to produce pure Ni products as well as by-products, such as cobalt (Co), copper (Cu) and precious metals.
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 …

The DNi Ni Process™ The DNi Ni Process™ is a unique technology which can process the full laterite ore profile (limonite, saprolite, and transition zone) with nitric acid, and which extracts all the metals contained in the feed. Boasting a 99% nitric acid recovery rate, our DNi Ni Process™ minimises environmental impact.
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 …
also limited to concentrate the nickel. The mined ores (1–4% Ni) are processed to upgrade the metal content with 10–20% Ni in the concentrates. Thus, the preconcentration of nickel ores is an important unit operation to upgrade the nickel before commencing any extraction steps. Ni is mined from sulfide ores, Nickel ferrolaterite and serpentine.
Looking Ahead: The exploration of deep-sea nickel deposits and the development of bio-mining technologies, which use microorganisms to extract nickel from low-grade ores, represent the frontier of nickel production. These innovative approaches could revolutionize how nickel is produced, making it even more integral to our push …
The demand for nickel and cobalt continues to rise due to their essential roles in a wide range of industrial applications. Although laterites account for 70% of global nickel reserves, the extraction of nickel from laterite ores is complex and requires different methods for each layer of the ore body due to differences in mineralogy.
After identifying a viable iron ore deposit, the extraction process begins. The extraction methods used depend on factors such as the depth of the deposit and the geology of the surrounding area. Here are two common extraction methods: a. Open-Pit Mining: Open-pit mining is employed when the iron ore deposit is close to the surface …
