## Refining process of copper blisters plant

Mar 24, 2021

The resulting copper from this step is known as blister copper. Blister copper undergoes further firing and purification to remove any remaining impurities. One of the main side effects of the copper smelting process is the production of waste. Refining copper results in three and a half times as much waste as the amount of copper produced
