Lateritic nickel ore deposits - Wikipedia

The ore is stacked on impermeable plastic membranes and acid is percolated over the heap, generally for 3 to 4 months, at which stage 60% to 70% of the nickel-cobalt content is liberated into acid solution, which is then neutralised with limestone and a nickel-cobalt hydroxide intermediate product is generated, generally then sent to a smelter for refining.

A turpentine based product (TBP) increased the copper recovery by 1.5–2% in the bulk concentrate as compared to the results obtained with potassium butyl xanthate on a rebellious copper-nickel ore containing 2.15–2.3% Cu and 1.04–1.1% Ni. However, the poor nickel floatability into the bulk concentrate indicated that TBP can be an effective flotation reagent for
