The Processes of Circuit Board Recycling

 · With all the precious metals that are hidden within circuit boards people aren’t always taking the safest approach to removing them. A good example of this are places like China and Africa. In both countries children and families work, with no safety equipment, to remove the lead, gold, copper and other metals from the e-waste that builds up .

Printed Circuit Board Recycling Methods 1. Introduction to Printed Circuit Boards The Printed Circuit Board (PCB1) manufacturing process is very complicated, involving many special chemicals and valuable materials. These materials discharge into the environment in the forms of wastewater, spent solution and solid waste.

PCBRec process: Waste Printed Circuit Board (WPCB

Every year about 400,000 tons of waste printed circuit boards (PCBs, see Figure 1 for an example) are collected in Europe representing a large resource of precious, critical and other metals such as gold, platinum, palladium, copper and solder; often in concentrations significantly higher when compared with their ores i.e. copper (0.5–1% copper), gold (1–10 g/ton gold).

PCBRec process: Waste Printed Circuit Board (WPCB

Recovering particle materials from discarded printed circuit boards can enhance resource recycling and reduce environmental pollution. Efficiently physically separating and recovering fine metal particles (−0.5 mm) from the circuit boards are a key recycling challenge. To do this, a new type of separator, an inflatable tapered diameter separation bed, was developed to study particle motion .

 · One metric ton of circuit boards can contain 40 to 800 times the amount of gold and 30 to 40 times the amount of copper mined from one metric ton of ore in the US. This e-waste is a particularly rich source of precious metals—with concentrations 40 to 50 times more abundant than naturally occurring in ore deposits.

Electronics Recycling- Rich Source of Precious Metals

 · A dismantled key-board A waste key-board falls under the category of small WEEE but it is an exception which is clearly visible when being dismantled. Almost whole of it contains plastic and polymer in the form of keys and cover but it contains a small PCB which is very small in size compared to other components.

Electronic Components (EC) Reuse and Recycling – A New

 · A typical recycling process converts large quantities of items made of a single material into more of the same. However, this approach isn’t feasible for old electronic devices, or “e-waste,” because they contain small amounts of many different materials that cannot be readily separated.
