Recovery of Nickel and Iron from Lixivium of Nickel Laterite Ores

Abstract:

The joint technics on sodium jarosite process and solvent extraction technique for lixivium of nickel laterite ores has been investigated. The results indicate that a Fe₂O₃ product with Fe grade of 58.12% could be obtained by precipitation separation and roasting, the total recovery of iron reaches 94.87%.Under the conditions of extracting temperature for 30°C, phase ratio 1:1, blance time 10min, pH = 5.5, the percentage extraction rate of Ni reaches 99.04%. When the 3 mol/L H₂SO₄ solution was used as stripping agent, the stripping rate of Ni reaches 97.52%. The total recovery of nickel reaches 94.56%.
