Precious Metal Gold Extraction Equipment from E-waste
With the rapid development of science and technology, the replacement of electronic products is becoming more and more frequent, and electronic waste (E-waste) is also being produced in large quantities. If these discarded electronic devices are not properly handled, they not only take up space but also may release heavy metals, halogenated flame retardants, and other harmful substances. However, E-waste is not useless, it contains a lot of recyclable resources, especially gold and other precious metals. Compared with traditional mining, extracting gold from e-waste not only has a higher economic value but also effectively reduces environmental damage, which has important environmental significance.
Precious Metal Gold Extraction Equipment from E-waste
Electronic waste contains a large number of electronic components, such as motherboards, CPUs, gold fingers, connectors, etc., which are the key objects for gold recovery. Gold in most of the gold-plated layers, solder joints, or pins in the form of existence of gold, although the gold content of each component is tiny, the cumulative potential for gold extraction is huge. According to relevant data, from a ton of electronic waste can be extracted about 200 grams of gold, much higher than the amount of gold obtained by mining a ton of ore, so electronic waste is known as the “city mine”, its development and utilization prospects are very broad.
To achieve efficient and environmentally friendly extraction of gold in electronic waste, it is recommended to use a complete set of specialized recycling equipment. The first stage is physical pretreatment, including automatic dismantling machine (PCB board for accurate dismantling), vibrating sieve machine (the material according to the particle size classification), magnetic separator and electrostatic separator (separation of metal and non-metal), and high-efficiency milling machine (the components will be crushed to the size suitable for chemical reaction). In the chemical treatment stage, the gold is converted to a soluble state through a leaching reaction, which requires equipment such as a leaching reactor, agitation tanks, and an automated cyanide or environmentally friendly alternative leaching agent dosing system. To prevent secondary pollution, it is also necessary to configure the waste liquid treatment system to purify the harmful components in the wastewater.
After the formation of gold solution, it is also necessary to pass the efficient separation and purification link, recommended equipment such as activated carbon adsorption tower (can be highly efficient adsorption of gold ions in the solution), electrolysis gold extraction device (gold reduction to the metal state), as well as centrifugal concentrator (extraction of the remaining gold particles). When choosing the equipment, we need to consider the processing capacity and recovery efficiency, the degree of automation and ease of operation, environmental performance (whether it complies with international standards), investment and maintenance costs, and whether it is easy to integrate with the existing system. SUNY GROUP's high-efficiency, environmentally friendly, and automated equipment plays a decisive role in the whole recovery process, which not only improves economic efficiency but also promotes the recycling and green development of resources.
