The Goro Nickel mine is the largest mining projects in New Caledonia. Around 4 million tonnes of dry ore are expected to be removed each year at the Goro Nickel site in New Caledonia. Equipment for the Goro Nickel plant is being supplied by , ABB, Cimprogetti. Haulage is undertaken at the site in New Caledonia by a fleet of dumper trucks.
The laterite ore is leached as a slurry in a pressure acid leach containing an excess of aqueous sulphuric acid at high pressure and temperature, excess free acid in the leach slurry is partially neutralized to a range of 5 to 10 g/L residual free H 2 SO 4 and washed to yield a nickel and cobaltcontaining product liquor, the product liquor is subjected to a reductant to reduce any Cr(VI) in solution to Cr(III), the .
Nickel (Ni) ore processing Rigaku Global Website. Background In the processing of nickel, typically lateritic ores or sulfidic ores are first crushed and milled to a fine powder. Water is added to create a pumpable slurry, which is treated with reagents during the flotation process in order to concentrate the nickel.
