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).

Primary world nickel production in 2020 was 2430.7 kt Ni; 69% (1677.7 kt) of them came from oxidized nickel ores (laterites) and 31% from sulfides. Production-wise, 87.7% of the 1677.7 kt came from pyrometallurgical and 12.3% from hydrometallurgical processes. For a long time, Fe-Ni had a 20–40% Ni analysis, but in 2006 a new Fe-Ni quality came into the scene. This is the …
