Electronic waste precious metal extraction equipment

For the current society out of scrap electronic waste, electronic circuit board cards and other electronic components contain a large number of precious metals, the equipment uses mechanical crushing crushing physical sorting and other technical processes. The non-ferrous metals and precious metals are separated effectively and cleanly, and high value metals such as copper, aluminum, tin, lead, gold, silver, palladium, platinum and tantalum can be obtained. The whole process is low noise and dust-free, which is a very good production line for recycling circuit boards at present.

In the reality of the application of gold, silver, palladium and platinum, will produce a large number of scrap and old products, due to the nature of waste, types and shapes vary widely, for the treatment of gold-containing scrap, requires a higher degree of technology and equipment targeted extraction, only then can we obtain a better recovery rate and emissions up to the economic and technical indicators.

For precious metal sorting refining extraction equipment workflow, first disassembled can not return to the chip, north and south bridge, storage chip, integrated circuit, plastic field effect are in the components containing gold and silver amount of collective materials in line with the unified treatment of components, available plus ozone roasting, roasting slag using soluble carrier, leaching copper, lead and tin, hydrochloric acid medium leaching gold platinum palladium, extraction of gold, platinum, palladium. For chip capacitors containing high silver and palladium independent extraction of silver and palladium, the gold-plated circuit boards, plug-ins recommended the use of environmentally friendly degolders rapid degold extraction of gold.

For silver and palladium sound surface, metal encapsulated triode, integrated circuits with special pin cutting machine to cut off the metal shell to punch out the chip after refining valuable metals according to the chip, integrated circuit program, for high aluminum electrolytic capacitors after dry laminating, crushing directly after melting out the metal aluminum, for voltage regulator diodes, part of the varactor diodes, such as glass sealed components, plastic sealed light-emitting tubes after laminating broken to refine valuable metals, for circuit boards Organic acid cycle leaching by liquid electrolysis output electrolytic copper, palladium-containing circuit boards (double-sided circuit boards basically contain palladium, palladium as copper plating base material contained in the guide hole as a wire) and then acid leaching palladium, and then extracted to refine palladium. The entire refining process has a lot of equipment, so I won't go into detail here.
