Eddy current sorter is designed by using the principle of induced current generated by conductors in high frequency alternating magnetic field. When working, a high frequency alternating magnetic field is generated on the surface of the sorting magnetic roller, and when a non-ferrous metal with electrical conductivity passes through the magnetic field, an eddy current is induced in the non-ferrous metal, and this eddy current itself generates a magnetic field in the opposite direction of the original magnetic field, and the non-ferrous metal (such as copper, aluminum, etc.) will leap forward along its transportation direction because of the repulsive force of the magnetic field to achieve separation from other non-conductors or non-metallic substances to achieve The purpose of sorting.
The raw material for gold refining, used circuit boards and electronic factory trimmings, is very rich and extensive, inexhaustible, and has a long-term retention. Electronic waste as a "secondary resource utilization" by various industries of great concern, the recycling process has become a hidden huge business opportunities of the industry. Runda's new gold extraction process uses wet total dissolution or selective dissolution and activated carbon adsorption to recover gold from electronic waste containing trace amounts of gold. This technology is a complete set of new wet refining technology to recover gold and silver and other precious metals from e-waste, through dissolution, adsorption, refining, drying and smelting processes, to obtain products containing gold (silver) can exceed the national standard gold (silver) standards. This technology treats electronic waste and can refine 30 kg of gold from more than 100 tons of electronic waste. The value is more than RMB 3 million.
The special equipment and tools and reagents used by Xingmao to refine gold and silver are very common and cheap, and can be bought in chemical stores everywhere. There are many methods to refine gold and silver from electronic waste and circuit boards: aqua regia method, thiourea method, hydrogen peroxide method, chlorination method, electrolysis method, etc. All of them have corresponding extraction methods according to the materials. Only if the methods properly correspond, can we improve the recovery rate. All other methods are practical, and we teach trainees an economical and practical technical method that corresponds appropriately during the training.
Circuit board crushing and recycling equipment characteristics are short process, easy operation, no pollution, less energy consumption, low cost, strong adaptability; can deal with high and low content of electronic waste; equipment is simple, investment saving, easy to achieve continuous industrial production; metal recovery rate is high, if the use of the unique gold, platinum purifier in this technology, its purity and recovery rate can reach 100%, electronic waste refining finished waste residue can be in accordance with a certain The finished electronic waste can be mixed into sand and gravel to make slag bricks according to certain ratio, which can become high quality wall building materials, or use the powder ground into PCB boards to make handicrafts, without solid waste emission. Traditional electronic waste treatment has caused a large number of pollutant emissions, the use of the process of gold, not only to protect the environment, economic benefits and good, the country and the people, killing two birds with one stone, this method is particularly suitable for small and medium-sized enterprises and individual practitioners.
