E-waste Precious Metal Separation & Refining Solution

E-waste precious metal refining recycling system provides an eco-friendly solution for refining and recycling valuable precious metals like gold, silver, palladium and platinum from electronic waste.

Features of E-waste Precious Metal Recycling Plant

• After proper treatment, waste water can achieve up-to-standard discharge.
• The recycling rate of precious metal (gold, silver, palladium and platinum) can reach up to 97% – 99%.
• The purity of precious metal is up to 99.99%.
• The operation process of E-waste precious metal recycling production line is with high degree of automation, saving human cost to a large extent.
• Adopting cyanide-free environmental protection hydro-metallurgy technology, the processing flow is short, greatly reducing the pollution to environment.

The fineness of precious metal can reach up to 99.99%. The equipment of e-waste recycling plant can be used to recycle all kinds of circuit boards, computer board, TV board, aluminum-plastic plate, copper board and printed circuit boards to make further economic benefits. As a matter of fact, there is much metal in circuit boards, for example, copper(about 40%), gold, silver and nickel. The proportion of gold,silver in printed circuit board is much more than that in gold ore mineral. Actually, there are many resources of e-waste containing precious metal in daily life, such as waste mobile phone circuit board, computer CPU, motherboard, VCD, CD, television board, game machine, fax machine, telephone board, mobile communication and other kinds of home appliances, industrial offal in electroplate factory, electronic parts and components factory, printing house, photosensitive material factory and electronic equipment factory, etc.

Two times mechanical pulverization makes PCB into the mixtures of metal and nonmetal powder. The air separation technology can realize the metal and non-metal complete separation and collection. The whole process can be realized in one production line, fully closed operation can ensure not creating any pollution. For instance, in the process of gold stripping, we use our patent chemical to strip gold from PCB surface, and extract gold from solution, which has no acid and some other harmful material for worker and environment. The equipment are easy to operation and use.
