Recycling PCB scrap is a detailed process that begins with the physical dismantling of the boards. This involves drilling and sorting to remove various components such as capacitors, motors, and semiconductors. The boards are then cut into smaller pieces, facilitating the separation of metals from non-metals.

Following the initial physical separation, recycling firms may employ pyrometallurgy, which involves heating the PCBs to extract metals. This process can reach temperatures up to 1600°C, transforming metals into a liquid state for recovery.

Alternatively, hydrometallurgical processes use chemical solutions to leach metals from the PCB scrap. This method involves several steps, including solvent separation, material precipitation, and ion exchange, to recover valuable metals.

Electrochemical processes are also used, where metals are dissolved in a solvent and then electrically deposited onto electrodes. This method is particularly effective for separating metals from non-metallic substances like resin.

Innovative biotechnological methods are also emerging, utilizing microorganisms to bind and recover metal ions. These processes are part of a broader effort to ensure that PCB recycling is environmentally responsible and does not release harmful substances into the ecosystem.

The most valuable components of a circuit board include transistors, resistors, capacitors, and diodes. These elements are essential for the functionality of electronic devices. Additionally, the metals used in the construction of the board, such as copper, gold, and silver, can be of significant value depending on their purity and the quantity present. Integrated circuits (ICs) are among the most crucial parts of a circuit board, often containing valuable materials like memory chips or microprocessors. The recovery of these components and metals from PCB scrap not only supports environmental sustainability but also offers a potential revenue stream from materials that might otherwise be discarded.

High-quality PCB scrap is characterized by its composition and potential for recovery of valuable materials. A PCB consists of an insulating material board laminated with a layer of copper, with precious metals on the surface acting as conductive elements.
