The method for the recycling of copper from copper chloride solution was developed.This process consists of extraction of copper,purification and particle size reduction.In the first,step,reductive metal scraps were added to acidic copper chloride waste enchants produced in the PCB industry to obtain copper powder. Composition analysis showed that this powder contained impurities such as Fe,Ni,and water.So,drying and purification were carried out by using microwave and a centrifugal separator.Thereby the copper powder had a purity of higher than g9% and spherical form in morphology.The copper powder size was decreased by ball milling.
