Lead plates stacked in an electro winning tankhouse at Kansanshi copper mine, Zambia
Lead plates acting as giant anodes stacked in an electrowinning facility at Kansanshi copper mine, Zambia. This is the final step in which copper rich electrolytes are pumped through a series of tanks or 'cells' in the electrowinning tankhouse. Insoluble lead plates hang in the tanks alternating with sheets of stainless steel (blanks) or sometimes thin copper (starter sheets). Each lead plate acts as an anode of the electric circuit. Blanks or Starter Sheets serve as the cathode. A direct current DC passes from the anode through the electrolyte to the starter sheet or blank, causing the copper ions in the electrolyte solution to plate or attach onto the starter sheet or blank. After a week in the tankhouse, roughly 50 kg copper sheets that are percent pure and ready for market are removed and stacked.
