Nickel characteristics - The All I Need

Historically most sulfide nickel ore bodies have had grades of 1% to 2% Ni, mined underground at relatively low production rates and with high operating costs. Laterite nickel deposits can be bulk mined, but the nickel can't be concentrated, so that both capital and operating costs are typically higher than sulfide projects.
