In the purification process,our professional workers can control the electricity,the rate of circulation and temperature.And they also can put additive into the electrolyte.
  • In short ,We mainly adopt electrolytic refining method which is used to obtain high purity copper.The pocess is highly purified of electrolyte with a higher purity of copper electrolysis again.
  • Depending on the type of electrolyte, the system can be divided into three kinds. First, the copper sulfate solution;Second,copper nitrate solution;Third,copper sulfate solution and copper nitrate solution.
