• All copper compounds are potentially toxic. Thus, we may be exposed to copper by breathing air, drinking water, food we eat through skin contact with copper or its compounds
• About 88 % of copper production comes from the processing of the minerals of this metal. The remaining of 12 % is provided by recycling of copper from wastes.
• The increasing demand of copper has made the production to increase quite a lot in the last
  years.
• Substantial savings can be obtained by reusing copper recovered from scrap.
• Substantial amounts of effluent of low copper content are generated in electrical and electronic parts manufacturing industries
• Hydrometallurgical process has been used for selective recovery of Cu, Ag, Au and Pd from waste printed circuit boards (PCBs)
• Copper recovery using leach/solvent extraction/electro winning technology is in practice for quite some time
• Electrochemical methods are becoming more frequently used in the prevention of environmental pollution
• Chemical dissolution process coupled with the electrochemical extraction is used to recover
  valuable metals selectively, such as Cu and Ni
• Recovery of metals by using Cathodic
  electrode position can be performed depending on the concentration of metal ions in the effluent
• The process, Electro dialysis by which electrically charged membranes are used to separate ions, the driving force of the process is a potential difference.
• Reactive electrodialysis, Electrochemical ion exchange, Electro coagulation, Electro flotation  are some of the other process used in specific situations
• Green process for cuprous chloride synthesis from waste printed circuit boards (PCBs) was developed
• The patented hydrometallurgical technologies are for the recovery of base and precious metals from sulphide and oxide feedstocks. It is based on the use of halide (chloride, bromide and iodide) chemistry to solubilise metals through the leaching process, followed by the recovery of high purity metals by electro winning or chemical salts.
