With the continuous depletion of high-grade nickel ores, nickeliferous laterites have become the major source for nickel production. This study investigates the effectiveness of calcining low-grade nickeliferous laterite followed by wet magnetic separation for nickel recovery. The calcination alters the crystalline structure of iron species, enhancing their magnetic properties and allowing selective concentration of nickel. The methodology involved varying calcination temperatures, pulp densities, and magnetic field strengths during the separation process. Experimental results demonstrated that nickel recovery can reach up to 48%, with the concentration of recovered nickel increasing from 1.5% to 2.9% after calcining the ore at 500 °C for 1 hour. The findings emphasize the impact of these parameters on the efficiency of nickel recovery, highlighting the potential of this environmentally friendly technique for processing low-grade laterite ores.
