How to use our reagent to get pure copper from copper ore?

2020-06-11

1.      Crush: Crush copper ore to particles:

 

 

2.      Leaching: use dissolve sulfuric acid to leach out the metal ions. This can use heap leaching or pool leaching, should base on the content of copper.

 

3.      Extraction: The leached ions should have Cu+, Fe+, Zn+, Mg+, Mn+, Ca+ etc. but our copper extraction reagent only extracting Cu+ out. The producing process is mixing and separation, now the copper ion is extracted to the organic phase (copper extraction reagent).

 

4.      Reverse extraction: Use 180 g/L Sulfuric acid to reverse extraction copper ion out to get pure CuSO4.


5.      Electrolyzation: Electrolysis the copper sulfate to get cathode copper:


6.      Our DZ988N’s selective of Cu:Fe is 2500:1, so the purity can over 99.96%. In practical, our engineer designed plant can get 99.9982% cathode copper.
