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 ...

It is one of the most widely used processes for extracting minerals like nickel from their ore – the natural rock or sediment that contains them. At the end of the flotation process, the nickel sulphides can be skimmed off and dried. Now at around 18% nickel, the concentrate is driven to Deception Bay, around 100km north of the mine.

The sulfating roasting process of nickel sulfide ore is essentially a process of selective oxidation of metals in minerals. In this process, air or oxygen-enriched air is generally used as oxidant, and a multiphase reaction takes place between solid phase and gas phase. After roasting, valuable metals such as nickel, cobalt, and copper are ...

Due to the relative ease of mining and processing, the high-grade mafic Ni sulphide ores have been depleted (Fig. 3) and processing the Ni-bearing laterite ore processing is expensive and challenging (Bobicki et al., 2015, Bobicki et al., 2012). Therefore, low-grade ultramafic sulphide ores represent an attractive Ni resource.

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).
