Rio Tuba Nickel Mining Corporation

Rio Tuba Nickel Mining Corporation started commercial operation in 1975. We export both saprolite and limonite ore to customers in Japan and China. Our customers use our ore for the production of ferronickel and nickel pig iron, both used to produce stainless steel, and for the production of pig iron used for carbon steel. We are also the exclusive supplier of limonite ore to the country's first hydrometallurgical nickel processing plant, Coral Bay. Coral Bay, as our partner, became operational in 2005 and currently operates at a capacity of 24,000 tonnes of contained nickel and 1,500 tonnes of contained cobalt per year in the form of a mixed nickel-cobalt sulfide. It has proven to be the world's most efficient facility using the high-pressure acid leach (HPAL) process.
