mining laterite nickel ore
Lateritic nickel ore deposits - Wikipedia
Nickel laterites are a very important type of nickel ore deposit. They are growing to become the most important source of nickel metal for world demand (currently second to sulfide nickel ore deposits). Nickel laterites are generally mined via open cut mining methods. Nickel is extracted from the ore by a variety of process routes. Hydrometallurgical processes include high-pressure acid leach (HPAL) and heap leach, both of which are generally followed by solvent extraction - electrowinning (SX-EW) for rec

Impacts of Laterite Mining of Nickel and Iron Ores on ...
p. 2 Impacts of Laterite Mining of Nickel and Iron Ores on Watersheds PREMISE Open pit, contour or strip mining of laterites involves removing 1 to 2 meters of topsoil to be able to extract the laterite, limonite and saprolite deposits which occupy the soil strata from 3 to 25 meters below the ground.

Dealing with Nickel-Cobalt Laterite Deposit Complexity
Most of the world's nickel reserves are in form of lateritic nickel ore deposits. Historically these were also the first source of commercially mined nickel sulphide ores, so that currently most of the nickel which has ever been produced came from nickel sulphide ores. Strong weathering of ultramafic rocks at the earth's surface in humid conditions causes nickel resources to form inside nickel laterites. Laterites are formed by the breakdown of minerals which then leach into

Two-thirds of the global nickel output can be attributed to the rotary kiln-electric furnace process. Due to the high contents of MgO and SiO 2 in laterite, a high temperature (∼1600 °C) and corresponding energy (approximately 14 GJ/t-ferronickel) are required during the electric furnace smelting. This work verifies the feasibility of decreasing the smelting temperature by controlling the ...
