Nickel Metal Rocks

Nickel is commonly found in iron meteorites as the alloys kamacite and taenite. The bulk of the nickel mined comes from two types of ore deposits. The first are laterites, where the principal ore minerals are nickeliferous limonite (Fe, Ni), O, (OH) and garnierite (a hydrous nickel silicate) (Ni, Mg), Si, O, (OH).
