【 摘 要 】

Laterite with low-grade nickel (2SO4 then was extracted using Cyanex 272 in toluene as an organic solvent. In this research, the effect of a voltage, a duration time of operation, a concentration of boric acid and a temperature on EMEW process were studied and were optimized using Taguchi method.
