Electronic Waste Precious Metal Extraction Equipment
E-waste often contains gold, silver, palladium, platinum, and other high-value precious metals, which are widely found in circuit boards, chips, communication modules, and other components. Compared with the direct mining of ores, the recovery of precious metals from waste electronic products is not only less costly, but also more environmentally friendly, and has become an important direction of resource recycling.
Extraction technology and equipment composition
The recovery of precious metals is usually divided into two stages: mechanical pretreatment and hydrometallurgy. Firstly, the raw materials are refined by a crusher and pulverizer, and with the help of magnetic separation, gravity separation, eddy current separation, and other technologies, the impurities such as iron, aluminum, and plastic are removed initially to enhance the enrichment degree of precious metals.
Subsequently, it enters into the wet metallurgy link, utilizing leaching tanks or stirring reactors to dissolve the precious metals in chemical reagents such as cyanide, sulfuric acid, or nitric acid. Through filtration, electrolysis, or precipitation equipment, the precious metals are efficiently extracted from the solution. The method has the advantages of a high recovery rate and adaptability, and is suitable for the recycling and treatment of many kinds of complex electronic waste.
Industry Trends and Future Prospects
With the tightening of environmental regulations and the development of the green economy, precious metal extraction equipment is being upgraded in the direction of intelligence and greening. Through AI intelligent regulation and automation control system, the extraction efficiency is improved and energy consumption is reduced; meanwhile, it is equipped with an exhaust gas treatment and waste liquid recycling system to realize the whole process of environmental protection and meet the standard.
SUNY GROUP automates and integrates the whole process from equipment dismantling, sorting, to precious metal purification, helping enterprises to realize resource reuse more efficiently.
