Copper is electrorefined from anode by means of electrolysis process using SS-blank as cathodes.

Copper anodes and SS blanks are inserted in altenatively electrorefining cells. By applying direct current to this cell, copper in anode is dissolved and deposited onto the SS-blank surface. Cu % in cathode is more than 99.99%. By products at Refinery are anode slime and copper telluride.
