Electronic Printed Circuit Boards contain many materials that are complex in nature, and they need a large amount of energy and other materials to make. Vast quantities of metals like copper, nickel and lead can also be found in them. Though they may be toxic, they are all very valuable resources.
Firstly, the components are all dismantled, pulverised and then shredded. The blank board and its components is the output from the initial processing stage; these blank boards mainly consist of smelted and electro-refined copper to create 99.9% pure copper bars. All separated components are then organised and classed as either heavy or light chips. All components are smelted so as to obtain pure metals, and all plastic components are separated by density-based separation.
