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.
