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 temperature in the range of approximately (5090 °C).
