Nickel is concentrated to over wt% and is hosted in a variety of secondary oxides, hydrous Mg silicates and smectites. The formation, mineralogy and grade of the deposits are controlled by the interplay of lithology, tectonics, climate and geomorphology.
Nickel is a silverywhite 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 Curie temperature is 355 °C (671 °F), meaning that bulk nickel is nonmagnetic above this temperature. The unit cell of nickel is a facecentered cube with the lattice parameter of ...
