Electrolytic copper purification

Electrolytic copper purification

You can refine copper - after extraction of raw materials - electrolysis, configuring ELECTROLYTIC cell where copper to be purified is the anode, while the cathode is a pure copper wire, and copper sulfate electrolyte (CuSO4) II, which dissolves in the solution

 - At the anode:

There are the following types H2O, SO42-a, pole of copper is pure (containing pole copper is pure impurities different each active him of such metals Zn, Fe and oxidized to cations Zn2 +, Fe2 + remains dissolved in the solution, and some less than active, such as metals, silver, platinum and gold, and that fall from the pole as a result of corrosion in the image of atoms in the bottom of cell analysis) and where that effort shorthand polar copper lower than water and sulfates, this oxidized atoms of copper electrode is pure and turn into cations dissolved in solution

B - at the cathode:

There are the following types H2O, Cu2 +, and where that effort reduction of water at the cathode =-0.41V, while effort reduced copper = + 0.34 V, and the most active metal cations of copper for this reduced copper cations to copper atoms deposited on the cathode

As a result purification electrolytic copper are:

Transmission of copper anode and deposition on the cathode

While turning zinc and iron impurities in the pole cations
