PCB / WEEE Precious Metal Recycling

PCB recycling equipment and technology supplied by Metalcess can have a efficient recovery of Copper and precious metals such as Gold and Silver. Pyrometallurgy serves as the primary process in our recycling system. As a Chinese new high-tech enterprise in metallurgy industry, Metalcess can design and manufacture TBRC furnace and TSL furnace. Compared with hydrometallurgical processes, the pyrometallurgical process for PCB recycling achieves a higher recovery rate of precious metals and is more environmentally friendly.

Raw Material

Waste printed circuit boards (PCBs) and Electronic waste materials from Waste Electrical and Electronic Elements (WEEE) such as waste household appliance, computer, TV, cellphone, industrial control equipment and so on.

Output Quality

99.99% Cathode Copper, Iron, Aluminum, precious metals(Au, Ag, Pt, Pd, Rh and etc), Se, Te, plastics, soldering Tin and etc

Process Description

Technological Process of PCB Recycling

Waste circuit boards should be pre-treated first.
The soldering Tin is removed manually along with heating and the reusable components are taken off. Then, through methods such as crushing, gravity separation, magnetic separation and cyclone separation, Iron, Copper, Aluminum, precious metals and plastics can be obtained. After separation, 90% of the metals and plastics can be separated and recycled. About 10% of the remaining materials can be landfilled or incinerated depending on their composition and properties.
About 50% of the metal components in used circuit boards are Copper, and there is also a considerable amount of gold and silver. The method of smelting and refining Copper can help a effective recover of gold and silver.
The sorted metals enter the subsequent smelting furnace to produce black Copper. TBRC furnace, Blast furnace, Oxygen enriched side blow furnace can be used for this process.
Then the black Copper will be coverted and further fire-refined to produce 98% Copper anode(crude Copper). PS Coverter, TBRC furnace and TSL furnace can be used for this process.
The Copper Anode containing precious metals produced by pyrometallurgical smelting enters the Copper electrolysis system (electro-refining process) to produce 99.96% Cathode Copper. The precious metals enter the anode slime and can be purified in the subsequent comprehensive recovery system to produce high-purity gold, silver, etc., or the anode slime can be sold out directly.

Core Equipment for PCB Recycling

The TBRC furnace and TSL furnace manufactured by Metalcess for PCB recycling are two high-efficient pyrometallurgical equipment, in which smelting, coverting, and refining reaction can be carried out in the same furnace. They are especially suitable for the treatment of complex electronic waste containing precious metals.By them, PCB after crushing will be directly feed into furnace without further sorting and separation process, thus reducing the loss of precious metals in plastics.

The benefits of TBRC and TSL furnace includes:

High recovery rate: Copper recovery rate ≥ 98%, precious metal recovery rate > 99%, and high resource utilization rate of glass fibers.

Environmental friendliness: High-temperature oxidation smelting reduces the generation of volatile organic compounds and is equipped with an integrated flue gas treatment system to effectively control dioxin and heavy metal pollution.

Strong adaptability to raw materials: It can handle raw materials with low Copper content, complex composition, and those containing precious metals.

Low production cost: Oxygen-enriched self-heating smelting reaction requires no extra fuel addition, saving fuel costs. For precious metal recycling from PCB and catalyst, comparing with hydrometallurgy PCB recycling method, produce 90% less waste water. The waste water treatment cost would be much lower.
