Copper Electrowinning Machine

With the worldwide exploitation of copper resources, the high-grade and easy-to-treat copper resources are decreasing day by day, and the proportion of low-grade and difficult-to-treat complex copper resources in the reserves of copper resources is increasing sharply. The pyrometallurgical copper smelting process not only requires high quality of copper resources, but also pollutes seriously. The copper electrowinning equipment of our company adopts hydrometallurgical copper smelting technology, suitable for low-grade copper ore. Low cost and no air pollution, and the purity of copper extracted can reach 99. 99%

1.Leaching: Using sulfuric acid leaching agent, copper in copper ore is leached in the form of copper sulfate solution.

2.Extraction: divided into first stage extraction and second stage extraction, using a unique extraction agent, only copper can be dissolved in the extraction agent, separated from other Impurities.

3.Stripping back extraction: Copper sulfate solution and extractant are obtained by stripping copper with sulfuric acid solution. The extractant can be recycled

4.Deironing: Remove base metals, such as iron, from copper sulfate solutions. Get a pure copper sulfate solution

5.Electrowinning: electrowinning treatment. The anode is made of lead alloy and the cathode is made of stainless steel plate

6.Copper attached to the cathode stainless steel plate, after removed and cleaned, then obtain copper with a purity of 99. 99%

1.Low investment and production costs, the production cost is lower than that pyrometallurgy method, and it has strong market competitiveness

2.Treating low-grade copper-containing materials, unique technical superiority

3.No pollution, in line with environmental protection requirement
