Many of the sulfide deposits occur at great depth. Laterites are formed by the weathering of ultramafic rocks and are a near-surface phenomenon. Most of the nickel on Earth is believed to be concentrated in the planet's core. Nickel is primarily sold for first use as refined metal (cathode, powder, briquet, etc.) or ferronickel.
