Ni and Co are commonly extracted from laterite oresLaterite ore through sulfuric acidAcid leachingLeaching, and spent acidAcid is typically not recycledAcid recycle. Rather, acidAcid is often neutralized with limestone or hydrated lime, resulting in CO2 emissions and solid wastes. Bipolar membraneBipolar membrane electrodialysisElectrodialysis (BPMED) is an energy-efficient and safe method for acidAcid recyclingRecycling, but commercially available BPMED systems are designed for producing relatively dilute (up to 2 mol H+/L) acidAcid solutions. Higher concentration acidAcid streams are desirable in many metallurgical leach processes for decreasing reactor volumes and facilitating solid/liquid separations. To make acidAcid recyclingRecycling more feasible in Ni and Co extractive metallurgy, we are developing mechanisms for increasing output acidAcid concentration of BPMED systems toward 4 mol H+/L. Ore leachingLeaching experiments have been performed at bench scale to demonstrate the concept of process integrationIntegration with BPMED.
