Anyang YDN EAF can treat Waste circuit boards to get copper and tin metal.
After melting and cooling, copper and tin naturally separate into distinct layers on discarded circuit boards.
The resulting metals exhibit high purity.
DC arc furnaces have emerged as the key equipment for resource recovery of waste printed circuit boards (WPCBs) due to their high efficiency, energy savings, and superior precious metal enrichment capabilities, driving the advancement of the electronic waste recycling industry. Their core value lies in the dual efficacy of non-hazardous disposal and high-value resource recovery.
Technologically, DC arc furnaces create a molten environment through high-temperature arcs, enabling direct processing of waste circuit boards. This facilitates efficient separation of metals like copper, gold, and silver, achieving 100% palladium recovery and over 99.8% recovery rates for both gold and silver. Compared to AC furnaces, its natural power factor reaches 0.95-0.98, eliminating eddy current and skin effect losses. This reduces overall power consumption by 15% and graphite electrode consumption by over 30%, significantly lowering processing costs.
In industrial applications, the equipment accommodates capacities ranging from 50kVA to 30,000kVA, serving both small-to-medium recycling plants and large-scale projects processing up to 30,000 tons annually. When integrated with exhaust gas purification systems, it controls pollutants like dioxins and heavy metals in incineration fumes within national standards, ensuring environmentally compliant emissions.
Currently, Anyang YND DC arc furnace has established a mature process for directly extracting non-ferrous metals from circuit boards. Its recovery rate far exceeds traditional hydrometallurgical methods, providing an efficient solution for the circular economy of electronic waste.
