Extracting copper. Extracting copper.

2014-6-13  Many metals are impure when they are extracted from their ores. Impurities have to be removed. Copper is purified by electrolysis. In this process copper is transferred from an impure anode to the cathode of an electrolytic cell. The insoluble impurities fall to the bottom. The copper produced by this process is 99.99% pure copper.

Extraction Of Copper Mining, Concentration,

The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. \(Cu^{2}S + O^{2} → 2Cu + SO^{2}\) The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2 leaves. This causes the final product to have a very blistery appearance and hence it is called Blister Copper;

Extracting Metals from E-Waste Yale Scientific

2018-1-30  Dissolved copper, for example, needs about two volts of potential to maximize recovery. O’Connor discovered that although two volts works well for copper, different voltages work well for other metals. This finding means metals can be individually retrieved from waste streams according to the type of voltage applied.

Current Status and Future Perspective of Recycling

2016-1-1  Electronic waste, especially waste print circuit boards contain large amounts of copper, which not only bring greater ecological threat, but also cause a serious waste of copper resources. Therefore, the study on clean, effective copper leaching technology has a very important practical significance to reduce environmental hazards of waste print circuit board and resources recycling.
