Abstract

Low-grade laterite which has nickel content 0.5% has been processed using solvent extraction and followed by electrowinning process. Cyanex which diluted in toluene was used as an organic solvent to separated cobalt from nickel solvent. In this work, nickel solvent which frees from cobalt was processed using electrowinning. Electrowinning was conducted using batch recycle methods to ensure the electrowinning performed well. Meanwhile, cylindrical cathode electrode was used to increase the performance of electrowinning, easy to operate and easy to harvest. The parameters which have a significant effect in batch recycle methods such as flow rate, voltage and process duration. Taguchi analysis showed the optimum condition and the parameter which has the highest effect towards the mass of nickel electrodeposits.
