The plant processes the nickelferrous ores (laterites) we mine to produce ferronickel with an 18%-24% nickel content. This is the raw material for the industrial production of stainless steel in Europe. The total quantity of ore processed per year is 2,500,000 tonnes, equating to an annual ferronickel production of around 18,000-20,000 tonnes.
