However, with the right technology, this waste could become a sustainable source of precious metals. Such a solution requires selectivity towards the precious. It's true that there is often silver, platinum, palladium and gold in our damaged or outdated electronics, not to mention plastic, glass and other materials that have some scrap value. The main reason is that precious metals conduct electricity much better than alloys.
They also have properties such as corrosion resistance and hardness that are important in electronic devices.
Precious metals
such as silver and palladium are used in many industries. For example, silver is used in nanomedicine and electronics, and palladium is important as a catalyst. Demand for these metals increases as natural resources are depleted, so recovering them from waste is an ideal solution.Recycling metals also reduces pollution, since silver and palladium ions are toxic to living organisms. 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. Precious metals such as gold, copper, silver, platinum and others are widely used in electronic applications in mobile phone PCBs, computer motherboards and connectors, due to their high conductivity, low ampere current carrying, high sensitivity and corrosion resistance. These precious metals are reprocessed and reused.
As described in Sections 2 and 3, technologies for recycling precious metals from spent e-waste and catalysts have been improved with the goal of increasing the recovery rate and reducing environmental pollution. In order to achieve environmentally friendly and sustainable recycling of precious metals with a high recovery rate, several considerations have been proposed. The recovery of precious metals can be successfully carried out from waste, which are considered secondary sources of raw material. The main types of electronic waste recovery from precious metals include palladium, copper, gold, silver, nickel and platinum.
Nitrogen in the form of NH4Cl was successfully recovered from the PL, which was significantly influenced by the initial pH. CRT monitors contain hazardous materials and must be processed by a specialist to safely recover recyclable metals (such as lead extraction from leaded glass). The ammonia leaching process was often used to separate precious metals from rare earths during their recovery through hydrometallurgy, resulting in the generation of nitrogen-rich leachates. Therefore, it is necessary to summarize the current state of technologies for recovering precious metals from spent e-waste and catalysts.
Innovative practices in precious metal recovery are a key trend that is gaining popularity in the precious metal electronic waste recovery market. 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. You have outdated or outdated IT equipment that is ready to be discarded, and you've also heard that there are gold, silver, and other precious metals in electronic devices. It seems that the hydrometallurgical route will be a key player in the recovery of base and precious metals from electronic waste.
Precious metals are used in a wide range of applications, both in electronic and communication equipment, spacecraft and jet aircraft engines, as well as for mobile phones or catalytic converters. Apparently, recovering precious metals from e-waste and spent catalysts is crucial from the perspective of economics and environmental protection (Bigum et al. Companies in the precious metal electronic waste recovery market focus on innovative practices to recover precious metals from electronics more efficiently. .
