Extraction of Copper: Detailed Process

Zinc, nickel, iron, and other contaminants are accumulated as anode mud beneath the anode. Long-term exposure of copper pyrites to air and precipitation produces a diluted solution of copper sulphate. The addition of scrap iron can precipitate copper from this solution. The product is then refined electrolytically.

4.1.6.2: The Extraction of Copper

Metals above copper in the electrochemical series (like zinc) will form ions at the anode and go into solution. However, they won't get discharged at the cathode provided their concentration does not get too high. The concentration of ions like zinc will increase with time, and the concentration of the copper(II) ions in the solution will fall.

How is Zinc Extracted from Its Carbonate Or (Calamine)? Explain with

1. Concentrated carbonate of zinc is converted to its oxide by calcination. In this process, zinc carbonate ore is strongly heated in the absence of air to produce zinc oxide and carbon dioxide gas. 2. Zinc oxide is then reduced by coke (carbon). When zinc oxide is heated with coke, carbon acts as a reducing agent and reduces zinc oxide to zinc.
