Smallest Precious Metal Recycling Machine

Electronic waste is rich in Au, Ag, Pt, Pd, Li and other rare and precious metal resources. Recycling the rare and precious metals can not only solve the problems of environmental pollution of electronic waste, but also generate considerable economic benefits.

At present, pyrometallurgical and hydrometallurgical recycling technologies are the mainstream technologies for recycling rare and precious metals from electronic waste. Biometallurgical recycling technology will gradually mature, and in the future, it may be applied in the field of recycling of rare and precious metals in electronic waste on a large scale. Supercritical fluid recovery technology may eventually exist as a secondary recovery technology.

The recovery process of rare and precious metals in electronic waste is mainly divided into three stages: pretreatment, recovery and refining and purification. The pretreatment process includes the dismantling, crushing, sorting, conventional pyrolysis and microwave pyrolysis of electronic waste. The purpose of the recovery stage is to extract and enrich the rare and precious metals in the metal-rich body to prepare for subsequent refining and purification. The recovery process includes pyrometallurgical recovery, hydrometallurgical recovery, biometallurgical recovery and supercritical fluid metallurgical recovery technology. Refining and purification is the process of obtaining rare and precious metals with higher purity from recovered base metals or precious metal leaching solutions by means of pyrorefining, electrolytic refining and chemical refining.

Precious metal sorting, refining and extraction equipment is used to sort and refine precious metals gold, silver, palladium and platinum from electronic waste containing precious metal chip components and anode slime. The purity of precious metals can reach 99.99%.

Smallest Precious Metal Recycling Machine Workflow:

SUNY GROUP's work flow of precious metal sorting, refining and extraction equipment, chips, north-south bridges, memory chips, integrated circuits, and plastic packaging field effects that cannot be returned after dismantling are all components that contain gold and silver in the components. Ozone can be added for roasting, and the roasting slag can be leached with a solvent carrier, leaching copper, lead tin, and hydrochloric acid medium to leaching gold, platinum, and palladium, and extracting gold, platinum, and palladium. For chip capacitors with high silver and palladium content, silver and palladium are independently extracted. For gold-plated circuit boards and plug-ins, it is recommended to use an environmentally friendly gold stripper to quickly strip and extract gold.

For silver- and palladium-containing acoustic surfaces, metal-packaged triodes, and integrated circuits, use a special pin-cutting machine to cut off the metal shell and punch out the chip, and then extract valuable metals according to the chip and integrated circuit scheme. After crushing, metal aluminum is directly smelted. For Zener diodes, some varactor diodes, other glass-sealed components, and plastic-sealed luminous tubes, valuable metals are extracted after being crushed. Electrolytic copper is produced, palladium-containing circuit boards (double-sided circuit boards basically contain palladium, and palladium is used as a copper-plated substrate and contained in the conducting holes used as wires), and then palladium is leached with acid, and then palladium is extracted and extracted. There are many equipments in the whole refining process, which will not be described in detail here.
