What is copper used for in everyday life?

Copper is the second most important non ferrous metal and is used in many industries ranging from healthcare to construction, machineries to electronics, and telecommunication. 

In order to overcome this issue, metallurgical industries have started utilizing metal-bearing solid wastes for the recovery of metals. Almost 15% of Cu is presently produced from secondary Cu resources such as alloys and scraps. Nowadays many waste materials (metallurgical sludges, residues and slags, etc.) are including extractive metallurgy of Cu.

Besides this,The precious metals that are present in PCBs,which has considerable material value, such as copper (%27) is available in high quantity.  Hence, effort is directed to recover precious metals from PCBs, through best convenient technologies, to reduce on primary metal resources. 

Which methods are most preferring on recovery of copper from PCB ?

Two major techniques, Pyrometallurgical and Hydrometallurgical, were widely used for recovery of copper from PCB.

Pyrometallurgy is a traditional technology for recovery of non-ferrous metals. Pyrometallurgy includes incineration, smelting in a plasma arc furnace or blast furnace, drossing, sintering, melting and reactions at      high temperature. Hydrometallurgy is another traditional technology for the recovery of precious metals from waste PCBs. Hydrometallurgy method has been preferred more in the last decade due to it’s pilot scale applicability, high metal recovery efficiency, no harmful gas outlet and no dust problem.

How do recovery of copper by electrorefining method ?

Firstly the anodes of impure copper are refined by electrolytic means to the pure cathode copper in the refining tank.  It is filled with a solution of electrolyte , in which the anodes and cathodes are interleaved and immersed between anodes are suspended starting sheets which are thin sheets of  electrolytic copper.

The cathode sheets remain in the tank until sufficient copper from the anode has been deposited on the cathode. Impurities which is below copper stay as metal and fall to the bottom of the refining tank as “anode sludge”. Operation cells and power adjustment units provides 99.99% purity copper and silver is recovers at this step.
