Nickel Laterite Ore Deposits: Weathered Serpentinites

Nickel laterite ores account for over 60% of global nickel supply. They are the product of intensive deep weathering of serpentinites under humid tropical conditions. Nickel is concentrated to over 1.0 wt% and is hosted in a variety of secondary oxides, hydrous Mg silicates and smectites.

Extraction of Nickel, Cobalt and Iron from Laterite Ores

Lateritic ores are formed by prolonged weathering of ultramafic rocks. The laterite deposits exhibit graded layers of ore, with high iron, low nickel ore on top and low iron, high nickel ore below. The low iron (< 15 % Fe) ores containing 1.7 — 2.3% Ni are treated by pyrometallurgical processes to produce ferronickel or matte.

ESG and Nickel Wading Through the Issues Benchmark

Nickel is produced from two primary resource types, sulphide ores and oxide ores more commonly referred to as laterites. Sulphide deposits tend to be located outside of the tropics (although there are a smattering of deposits in South America, South Africa and Australia).

Ni-Co Laterite Deposits of the World; Database and Grade

May 26, 2011· The United States has no active nickel mines or nickel reserves. Ni-Co laterite deposits provide one of two major natural sources of nickel and cobalt. The economic importance of this deposit type expands in direct relation with industrialization of developing countries. Until now, the world nickel supply has been predominantly from sulfide

Nickel-Cobalt Laterites—A Deposit Model USGS

Nickel-cobalt (Ni-Co) laterite deposits are supergene enrichments of Ni±Co that form from intense chemical and mechanical weathering of ultramafic parent rocks. These regolith deposits typically form within 26 degrees of the equator, although there are a few exceptions.

Nickel Statistics and Information USGS

The bulk of the nickel mined comes from two types of ore deposits: laterites where the principal ore minerals are nickeliferous limonite [(Fe,Ni)O(OH)] and garnierite (a hydrous nickel silicate), or magmatic sulfide deposits where the principal ore mineral is pentlandite [(Ni,Fe) 9 S 8 ].
