E Waste Scrap Precious Metal Extraction & Refining System

E waste scrap precious metal extraction & refining system is used for recovery and refining precious metals such as gold, silver, palladium and platinum from electronic waste containing precious metal chip components and anode mud.


Application: e waste scrap recycling, gold recycling, precious metal recycling


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 (PMs) in e-waste E-waste precious metal refiningsuch as gold (Au), silver (Ag), platinum (Pt), Gallium (Ga), palladium (Pd), tantalum (Ta), tellurium (Te), germanium (Ge) and selenium (Se) 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 Plantprinting house, photosensitive material factory and electronic equipment factory, etc. With over 300 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 300-350g/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.

Precious Metal Extraction & Refining Process

In fact, there is a good deal of metal in circuit boards, including copper(about 40%), gold, silver and nickel. The proportion of gold and silver in printed circuit board is much more than that in gold ore mineral. So this precious metal recycling plant is used to deal with waste circuit boards to make further economic benefits. In virtue of easy operation, people can use our precious metal refinery machine and patent chemical to strip gold from PCB surface, and extract gold from solution. And the process of gold stripping has no acid and some other harmful material for  workers and surroundings. Recycling of e-waste for metal recovery is also important from the perspective of saving energy.


1. High extraction technology and accurate evaluation.
2. It is a safe and eco-friendly system with short processing flow due to adopting cyanide-free environmental protection hydro-metallurgy technique, greatly reducing the pollution to environment.
3. Liquid waste can discharge to reach standard after processing.
4. The re-utilization rate of precious metal(gold, silver, palladium and platinum) can reach up to 97% – 99%.
5. The fineness of precious metal can reach up to 99.99%.
6. With highly automated operating process, our E-waste precious metal recycling plant can significantly cut down labor cost.
