Nickel is a silvery-white metal with a slight golden tinge that takes a high polish. It is one of only four elements that are magnetic at or near room temperature, the others being iron, cobalt and gadolinium.Its Curie temperature is 355 °C (671 °F), meaning that bulk nickel is non-magnetic above this temperature. The unit cell of nickel is a face-centered cube with the lattice parameter of

Although nickel is documented being used as far back as 3500 BC by Syrians who used a small amount and in 235 BC by the Chinese who minted coins from nickel, nickel mining itself is relatively new compared to other mined materials. Dating back to 17th century Germany, nickel was discovered in a red-colored ore that German miners believed was

Nickel mining in New Caledonia is a major sector of the New Caledonian economy. The islands contain about 7,100,000 tonnes of nickel which is about 10% of the world's nickel reserves. With the annual production of about 107,000 tonnes in 2009, New Caledonia was the world's fifth largest producer after Russia (266,000), Indonesia (189,000), Canada (181,000) and Australia (167,000).

Nickel is commonly present in two principal ore types—sulfide or laterite. Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt (Co), and often precious metals such as gold (Au) or platinum (Pt), palladium (Pd) and rhodium (Rh) (the platinum group metals or PGMs) (Naldrett, 2002, Hoatson et al., 2006).
