In recent years, with the rapid development of the electronics industry, the update rate of home appliances such as mobile phones and computers is getting faster and faster, and many waste home appliances are discarded casually. Experts say that these discarded electronic wastes still have good use value. For example, some old mobile phones, computers and other parts can be picked out of gold-containing components to extract gold. Every year, hundreds of thousands of tons of gold-containing waste need to be processed. . In 1 ton of electronic boards, 0.45 kilograms of gold, 1 kilogram of silver, 130 kilograms of copper, and 20 kilograms of tin can be separated. "Electronic waste" has become an industry that hides huge profits.

Precious Metal Refining Machine

With our process, the recovery rate can reach 99% and the purity is 99.9%. According to our many years of refining experience, 1 ton of electronic boards can extract 350 grams of gold, 2 kilograms of silver, 120 kilograms of copper, 25 kilograms of tin, 10 kilograms of palladium capacitors, 10 kilograms of nickel-containing parts, 400 kilograms of light plates, etc. (with detailed content , price list), and the refining of gold and silver from scraps of electronics factories is even more impressive.

The raw materials for gold extraction are waste circuit boards and scraps from electronics factories, which are very rich and extensive, inexhaustible and inexhaustible, and have a long-term reserve. E-waste as a "secondary resource utilization" has attracted great attention from various industries, and recycling has become an industry that hides huge business opportunities. The new gold extraction process from Mount Tai adopts wet full or selective dissolution, and activated carbon adsorption recovers gold from electronic waste containing trace amounts of gold. This technology is a relatively complete new wet extraction technology for recovering precious metals such as gold and silver from electronic waste. (Silver) standard product. This technology treats electronic waste and can extract 30 kilograms of gold from more than 100 tons of electronic waste. worth more than 3 million yuan.

It has the characteristics of short process flow, convenient operation, no pollution, low energy consumption, low cost and strong adaptability; it can handle high and low content of electronic waste waste; simple equipment, low investment, easy to realize continuous industrial production; metal recycling If the unique gold and platinum purifying agent in this technology is used, its purity and recovery rate can reach 100%, and the waste slag after e-waste extraction can be mixed with sand and gravel in a certain proportion to make slag bricks, which will become high-quality slag bricks. Wall building materials, or powder made from PCB boards to make handicrafts, no solid waste discharge. The traditional electronic waste treatment results in a large amount of pollutant discharge. Using this process to extract gold not only protects the environment, but also has good economic benefits.
