Background of the Equipment
Precious metal resources are scarce and costly, so scrap materials containing precious metals possess high economic value. Gold recovery from electronic waste boasts simple processes and low operation costs, which realizes turning waste into treasure. Hence, the recycling and reuse of secondary gold resources are of great importance for sustainable resource development and environmental protection. Gold‑stripping treatment equipment serves as vital facilities for secondary gold recovery.
Applicable Materials
Gold‑plated scrap comes from diverse sources. Common household waste includes discarded mobile phone circuit boards, computer CPUs, motherboards, VCD players, optical discs, televisions, game consoles, fax machines, telephones and various communication household appliances. Industrial raw materials cover leftover scraps from electroplating plants, electronic component factories, printing plants, photosensitive material factories and electronic manufacturers.
Product Features
- It causes no corrosion to nickel or tin layers. Base materials will not discolor, and their corrosion‑resistant performance stays intact.
- Fast stripping speed, with an average rate of 0.5‑2 mm per minute.
- The stripping solution is free of cyanide and other toxic substances.
- It achieves selective stripping for targeted separation of gold.
- High efficiency and complete separation. The gold separation rate reaches 99%, and recovered gold features high purity.
Working Process
- Prepare the special gold‑stripping solution.
- Place gold‑plated scraps into the solution. Surface‑layer gold dissolves into the liquid, whereas base metals including lead, tin, nickel and iron will not be damaged. This is patented technology.
- Filter out impurities to acquire gold‑rich solution.
- Reduction process: add reduction powder into the gold‑bearing solution. Gold will be reduced into black gold powder and precipitate, and crude gold can be obtained eventually.
Core Advantages
The gold‑stripping treatment equipment is developed for stripping gold from gold‑plated materials of waste electronic products. It is one of the optimal gold‑recycling solutions. Its gold recovery rate can reach 99%. High‑purity gold products can be obtained through subsequent smelting processing.
