ABSTRACT

Separation/recovery of valuable metals such as nickel or tin from copper based alloys has recently attracted from the viewpoints of environmental protection and resource recycling. In this report, preliminary study on concentration and separation of nickel from copper based alloy dross using selective adsorption by chelate resin was performed. The chelate resin used in this study has absorbed copper ions more easily than nickel ions in the metal solution, which could allow the concentration/separation of the nickel from the copper base alloy solution. The final molar ratios of Ni and Cu ions in the two concentrated solutions were 70 and 99 % respectively after three-time flowing the solution through the chelate resin column.
