Nickel mine
A nickel mine is a mine that produces nickel. Some mines produce nickel primarily, while some mines produce nickel as a side-product of some other metal that has a higher concentration in the ore.
Nickel occurs in two general types of ores, sulfides and oxides. The most important sulfide ore is pentlandite (Ni9S8) although many other nickel sulfides are known. Furthermore, nickel is often a constituent of iron sulfides such as pyrrhotite. The principal (i.e. economically most important) nickel oxides are nickeliferous limonite ((Fe1−xNix)O(OH)·nH2O). Pentlandite supplies an estimated 65% of the world's nickel but nickel laterites constitute the largest reserves.
Nickel content of its ores is often only a few percent by weight.
Sulfide ores are subjected to comminution followed by froth flotation. Pentlandite and related minerals separate with sulfides of copper, cobalt, and iron.
Two hydrometallurgical methods have been developed to extract nickel and cobalt from nickel laterites, these processes are called sulphuric acid leaching and reduction roast-ammonia leaching. For high-magnesium silicates in lower profiles laterites the exploitation method used is smelting.
According to the intergovernmental International Nickel Study Group, in 2017 the countries with the largest volume of nickel ore reserves are Australia (19.5 million metric tons), Brazil (10.5 million metric tons), Russia (7.5 million metric tons), New Caledonia (6.5 million metric tons), Cuba (5.5 million metric tons), and the Philippines (just under 5 million metric tons). As of 2017, 33 countries produced nickel ore. Nickel production increased from 2000 to 2013 (when it peaked), decreased from 2014 to 2016, and recovered from 2017 to 2018.
As of 2017, the largest nickel mine operators are (in descending order of kilotonnes mined):
Other large nickel producers include Jinchuan Group Ltd., the largest nickel producer in China, and Sherritt, a Canadian company from Canada that refines nickel from lateritic ores and has operations in Canada, Cuba, Indonesia and Madagascar.
