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.

Sulfuric acid heap leaching of nickel The technique is an acid heap leaching process like that of the copper method in that it uses sulfuric acid instead of cyanide solution to liquefy the target minerals from crushed ore. The process has been urbanized by European Nickel PLC for the rock laterite deposits of Turkey and the Balkans.
PT Inco process employs the following steps: upgrading laterite ore to 1.8 Ni dewatering, calcining, reducing and sulfiding the dewatered material, smelting the sulfided calcine in an electric furnace to molten matte that contains about 26 Ni and converting to product matte that contains 78 Ni and is ready for refining.

Unfortunately, laterites do not easily lend themselves to heap leaching, the normally accepted method of treating low grade oxidic ores, although there are notable exceptions such as European Nickel in Turkey . For heap leaching to be successful, the ore has to have certain physical characteristics which allow it to be agglomerated and have the necessary integrity to form
