The concentrated ore is then smelted to produce a nickel-iron sulfide matte, which undergoes further processing to remove impurities, resulting in higher-purity nickel. For laterite nickel ores, the process starts with crushing and grinding the ore, followed by high-pressure acid leaching (HPAL) to dissolve nickel and cobalt.
