Rock and Mineral Resources Geology

Nickel deposits are generally found in two forms, either as sulfide or laterite. Sulfide type nickel deposits are formed in essentially the same manner as platinum deposits. Nickel is a chalcophile element which prefers sulfides, so an ultramafic or mafic rock which has a sulfide phase in the magma may form nickel

Enhanced methods for nickel recovery from low-grade ores

Low-grade ores, like nickel sulfide, are abundant on Earth. Nickel sulfide deposits contain high levels of magnesium silicate gangue minerals (MgO) and can be difficult to process with conventional flotation and smelting technologies. MgO is hydrophilic, which interferes with flotation of sulfide minerals, and reduces flotation recovery. In

Nickel Sulfide Versus Laterite The Hard Sustainability

Nickel is commonly present in two principal ore typessulfide or laterite ores. Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt, and sometimes other precious metals such as gold or platinum and palladium (generally grouped as platinum group metals or PGMs).

PENTLANDITE (Iron Nickel Sulfide)

Pentlandite is an important ore of nickel. However, it does not produce good crystals and is generally only found in massive form. It is commonly associated with other sulfides such as pyrite, chalcopyrite and pyrrhotite in basic igneous rock intrusions. These sulfide ore bodies are probably produced through magmatic segregation.
