Abstract:
A recovery method of nickel according to the present invention comprises pretreatment step to prepare a solution for electrolysis by adding hexanesulfonate salt to a treatment solution including nickel, and nickel recovery step to recover nickel in a metal form by electrolysis of the above solution for electrolysis. The present invention can produce nickel in high purity with simple process with low cost, and can recover and reproduce nickel in a metal form with at least 99.5% of high purity and at least 90% of recovery rate.
