Flow Diagram Copper Ore To Copper Sulphate

Copper electroplating fundamentals

Copper sulfate (CuSO4) provides a source of copper ions. Sulfuric acid (H2SO4) makes the bath conductive and acts as a charge carrier. Chloride ions (Cl-) combine with the organic species to form a complex that slows down plating rate on selective areas.

The Chemistry of Copper Electrolysis

purification of ores such as copper sulfide ore. Electrolysis uses an electrical current to move ions in an electrolyte solution between two electrodes. In copper electrolysis, when a current is applied, positively-charged copper ions (called cations) leave the anode (positive electrode) and move toward the cathode (negative electrode).
