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…

The nickel laterite challenge - Australian Mining

Nickel occurs in essentially two ore types; magmatic sulphides and ('wet' or 'dry') laterites. The sulphides typically are found hundreds of metres below ground with principle mineralisation including pentlandite (Ni, Fe)9S8. Major deposits such as those in Canada and Russia have historically provided the bulk of nickel production.

Microbial Recovery of Nickel from Lateritic (Oxidic ...

The nickel present in nickel laterites is in very complex form as well as the content of the metal is very less, hence the laterite ores have been neglected for nickel extraction. Because of such reasons the conventional mineral processing (pyrometallurgical and hydrometallurgical) techniques are not economically suitable for nickel extraction.

Enhanced methods for nickel recovery from low-grade …

Whether high-grade or low-grade, nickel ores need to be processed after mining, in order to upgrade their nickel content from 1-4% Ni to 10-20%. Concentrating the nickel ores usually takes place close to the mine site, and involves chemical and physical processes to crush the ore and separate the nickel-bearing and gangue minerals.
