Laterite Ore - an overview ScienceDirect Topics

Michael S. Moats, William G. Davenport, in Treatise on Process Metallurgy: Industrial Processes, 2014 2.2.3.1 Laterite Ore Upgrading. Laterite ores are upgraded before smelting or leaching. The upgrading entails gently crushing and/or grinding the ore and then separating the resulting small, soft, low-density Ni-rich laterized mineral particles from large, hard, dense, Ni-lean, unlaterized ...

A hydrochloric acid process for nickeliferous laterites ...

2016-3-15  To minimise reactor size and costs the nickel tenor from leaching should be as high as possible. To enable this to be achieved together with high extraction could require some sort of counter-current washing process. A New Caledonia serpentinite ore was leached at 80 °C and 30% w/v solids with 6 mol/L HCl containing 20 g/L Ni.

How to Recover Chromium Nickel Cobalt Laterite

2021-1-6  Research led to the development of a processing procedure that allowed recovery of up to 53 pct of the chromium values in the laterite as a concentrate containing 22.9 pct Cr (33.4 pct Cr2O3) with a 1.6:1 Cr-Fe ratio. The processing scheme that was devised takes advantage of several physical characteristics of the laterite materials.
