7.3 Nickel Ore Processing and Refining. Primary nickel is produced from two very different ores, lateritic and sulfidic. Lateritic ores normally are found in tropical climates, where weathering, with time, extracts and deposits the ore in layers at varying depths below the surface. Lateritic ores are excavated using large earth-moving equipment ...

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.

leaching (HPAL), Caron process, and direct nickel process (DNi) are the most common processes to treat lateritic ore [4]. HL process can be processed at ambient temperature, but it is a kinetically slow process, and the yield is low compared to AL and HPAL [5]. AL requires 1 bar pressure and tem-perature in the range of approximately (50–90 °C).
