Manufacturing process

  1. Prepare an acid copper sulphate electrolyte solution inside glass-lined special electrolysis vessels.
  2. Perform electrolysis where copper is deposited on electrodes as a fine powder using aluminum cathodes and copper or pure lead anodes.
  3. Detach the copper powder from the electrodes periodically using wooden-handled aluminum scraps so it falls to the bottom.
  4. Centrifuge and wash the removed powder with water until it is free of copper sulphate.
  5. Dry the cleaned powder on trays in an electrically heated oven with forced air circulation at 60°C to 100°C.

Market

The indigenous production of copper powder is around 7000 tonnes per annum against an estimated demand of 15000 tonnes per annum, indicating significant market potential.
