Because it is naturally occurring, it must be mined from deep within the earth instead of synthetically created in a lab. Called nickel ore, there are two main types of ore deposits: laterites, which are mainly composed of nickeliferous limonite and garnierite, and magmatic sulfide deposits, which are primarily composed of the ore mineral pentlandite.
In general, nickel has a silvery-white color, high toughness, is ferromagnetic and has excellent resistance to corrosion and rust. Some of its additional beneficial properties include its malleability, ductility, alloy-ability and high heat resistance—it has a melting point of 1453 degrees Celsius.
