Leaching method selection for Caldag lateritic nickel ore

Aug 01, 2017 The AHP results show that HL is determined as the most appropriate leaching method for the lateritic nickel ore. In addition, the AHP results were analysed using sensitivity analysis. The sensitivity analyses show that the rankings of alternatives transform from HL to HPAL when the economical main criteria decreases from 76.1% to 16.3%. Based

CSMS GEOLOGY POST: GARNIERITE: LATERITIC GREEN NICKEL

I have seen other references that indicate some garnierite is chrysoprase, a nickel-enriched chalcedony. The best that I can do is quote the “official” explanation from MinDat: “[Garnierite is the] generic name for a green nickel ore which has formed as a result of lateritic weathering of ultramafic rocks (serpentinite, dunite, peridotite)

Enhanced methods for nickel recovery from low-grade ores

An excellent example the use of PAL on low-grade lateritic nickel ores is the Ambatovy mine in Madagascar, a joint venture between Sherritt, Sumitomo, and Korea Resources. This is one of the largest lateritic nickel mines in the world, and has the capacity to produce 60 000 tonnes of refined nickel a year, for at least 29 years. This mine also

Laterite - Wikipedia

Bauxite ore is the main source of aluminum.: 65 Bauxite is a variety of laterite (residual sedimentary rock), so it has no precise chemical formula. It is composed mainly of hydrated alumina minerals such as gibbsite [Al(OH) 3 or Al 2 O 3. 3H 2 O)] in newer tropical deposits; in older subtropical, temperate deposits the major minerals are boehmite [γ-AlO(OH) or Al 2 O 3.H 2 O] and some
