- E-waste precious metal refining system is designed to refine and recover precious metals like gold, silver, palladium(Pd) and platinum(Pt) from electronic waste (e-waste) like circuit boards, including CPU, RAM, pins, and other computer components.
- E-waste is classified as hazardous material therefore should be managed properly. However, the presence of precious metals (PM) in e-waste E-waste precious metal refining such as gold (Au), silver (Ag), platinum (Pt), palladium (Pd) makes it attractive for recycling. Precious metals refining is an industrial process through which impurity present in electronic scrap material is eliminated and metals with a high purity are collected. The purity of refined precious metal can reach up to 99.99%.
- There are many common resources of scrap materials with precious metal in daily life, such as computers, equipment for information and communication technology like waste mobile phone circuit board, home appliances (e.g., TV, washing machines, air conditioners, and refrigerators, etc.), audio & video products and all of their peripherals, industrial offal in electroplate factory, electronic parts and components factory, E-waste Precious Metal Recycling Plant printing house, photosensitive material factory and electronic equipment factory, etc. With over 200 tonnes of gold used in electronic components such as IC, contacts and bonding wires each year, end-of-life electronic equipment offers an important recycling potential for the secondary supply of gold. For instance, gold concentrations could reach 290-345g/t for mobile phone handsets and 200-250 g/t for computer circuit boards, which requires specialized metallurgical processes treatment to recover gold and a wide range of other precious metals efficiently and in an environmentally sound way.
