of ore with 1.8% Ni and moisture 25% are needed. (75 000 tons dry ore x1.8%Ni = 1 350 tons Ni). This means 3 300 tons of ore per day is being processed (130 trucks of 25 tons each). 1 350 t nickel, that is 45 t nickel per day, are produced from this quantity of ore. However, our product is not only nickel, but an alloy made of 20%Ni and 80% Fe.
