Urban extraction of precious metals from electronic waste, such as printed circuit boards (PCBs), is not yet feasible due to the lengthy insulation process.
Recycling precious metals
involves a wide variety of starting materials. Recovering them also requires a wide variety of specialized knowledge, and not just technological knowledge.Precious metals
are found all over the world and must be transported to a recycling partner.The objective is to make them available for reuse in the production process as quickly as possible, preferably even in parallel with recycling. Above all, performance must be maximized and sampling must be reliable and transparent. Representation, purchase per pound plans, easy-to-read settlement reports, and a variety of payment plans, such as tolling, hedging and metal exchange programs, are value-added service options available to all precious metals refining customers. The use of electrical and electronic devices increases the amount of electronic waste worldwide, thus driving demand for recovery of electronic waste from precious metals.
Precious metals such as gold, silver, platinum and palladium are used in electrical and electronic devices for their properties such as malleability, high corrosion resistance, high conductivity and others. Recycling precious metals from waste provides a promising solution; however, conventional metallurgical methods entail high environmental costs and high energy consumption. In addition, selective extraction of precious metals is also a major challenge in the metal ion reduction process. Finding the right recycling process to maximize the return of your precious metals will help boost your business.
SLS has maintained a leading position in precious metals refining and asset recovery for more than 50 years. Companies in the precious metal electronic waste recovery market are focusing on innovative practices to recover precious metals from electronics more efficiently. More than 99% of the target elements in waste sources can be dissolved and precious metals can be recovered after a simple reduction reaction showing high purity (¥ 98%). The main types of electronic waste recovery from precious metals include palladium, copper, gold, silver, nickel and platinum.
The precious metal electronic waste recovery market consists of sales of precious metal waste recovery by entities (organizations, individual traders and associations) that recover precious metals from electrical or electronic devices. We believe that the dissolution of precious metals in the recovery process is the most difficult to complete (especially for platinum group precious metals), which is attributed to the chemical inertness of precious metals. Therefore, conducting ecological selective extraction of precious metals is the main direction of innovation for future scientists. We mainly analyze the mechanisms of recovery strategies through coordination theory and redox theory and explore the essence of selective recovery through the different potentials of the electrodes and the capacities of ligands of precious metals.
