From copper concentrates. The smelting and converting of copper sulfide concentrates result in a "blister" copper that contains 97 to 99 percent of the silver present in the original concentrate. Upon electrolytic refining of the copper, insoluble impurities, called slimes, gradually accumulate at the bottom of the refining tank. These ...

DECARBONIZING THE COPPER SECTOR
The copper production value chain consists of several processes with various GHG emissions sources (see Exhibit 2). The mining and concentration processes together contribute 65%–80% of the total emissions from mine-to-copper cathode production. More than one-third of the total emissions come from the use of electricity at mine sites

Open-pit copper mining, smelting, and production | Britannica
The heavy copper plates that have been shaped are called anodes. In the final extraction step—refining—any remaining minor impurities are removed from the anodes. The result is almost 100 percent pure copper. This metal will be sent to other plants to be made into products such as copper pipe and copper wire.

Copper Life Cycle
After mining, copper is produced by one of two process routes, pyrometallurgical (dry) or hydrometallurgical (wet). Smelting is a process of heating and melting ore to extract a metal like copper. Refining refers to any process that increases the grade or purity of the metal. After completing refining processes, copper cathode is generally 99.9 ...
