Nickel is typically found in two types of deposits: laterite deposits, which are the result of intensive weathering of surface nickel-rich rocks, and magmatic sulfide deposits. Nickel can also be found in manganese nodules and crusts on the deep sea floor, but currently these are not being mined, according to Geology.com. The main mineral sources of nickel are limonite, garnierite and pentlandite.
Few things are made of pure nickel. Instead, nickel tends to play a supportive and stabilizing role in industry materials; it is usually combined with other metals to produce stronger, shinier and more durable products. Nickel is commonly used as a protective outer coating for softer metals.
