Nickel - Wikipedia

Nickel is commonly found in iron meteorites as the alloys kamacite and taenite. The bulk of the nickel is mined from two types of ore deposits. The first is laterite, where the principal ore mineral mixtures are nickeliferous limonite, (Fe,Ni)O(OH), and garnierite (a mixture of various hydrous nickel and nickel …
