Nickel Statistics and Information | U.S. Geological Survey

Statistics and information on the worldwide supply of, demand for, and flow of the mineral commodity nickel. Nickel (Ni) is a transition element that exhibits a mixture of ferrous and nonferrous metal properties. It is both siderophile (i.e., associates with iron) and chalcophile (i.e., associates with sulfur).

Nickel and Cobalt Production - ScienceDirect

Flow sheet for smelting moist 1.5–2.5% Ni, low-Fe laterite concentrate to ferronickel. Reduction is production of metal by removing O from the metal's oxide mineral, e.g., NiO + C → Ni + CO. Ferronickel electric furnaces are round (15–20 m diameter) or rectangular (10 m wide, 25–35 m long). They each produce 100–200 tons of ferronickel/day.
