The useful life of electrical and electronic equipment (EEE) has been shortened as a consequence of the advancement in technology and change in consumer patterns. This has resulted in the generation of large quantities of electronic waste (e-waste) that needs to be managed. The handling of e-waste
Electronic waste, or e-waste, is an emerging problem with developed nations as with developing nations. In the absence of proper collection and disposal systems, awareness, and proper regulations, the problem is rather more acute in developing nations.
The proper metal extraction from e-waste is an important issue from the point of view of mineral shortage and environmental care to avoid pollutants recycling methods. Nowadays, the hydrometallurgical methods available to recover
Management of metal pollution associated with E-waste is widespread across the globe. Currently used techniques for the extraction of metals from E-waste by using either chemical or biological leaching have their own limitations.
Environmental contamination due to uncontrolled e-waste recycling activities is drawing increasing attention in the world. Extraction of these metals with biodegradable chelant [S,S]-ethylenediaminedisuccinic acid (EDDS) and the factors influencing extraction efficacy were investigated in the present study.
Burning e-waste to extract metals emits toxic chemicals (e.g. PAHs, lead) from e-waste to the air, which can be inhaled or ingested by workers at recycling sites. This can lead to illness from toxic chemicals.
Electronic waste is defined as a mixture of various metals, particularly copper, aluminum and steel, attached to different types of plastics and ceramics. The samples for experimental research presented in this paper were milled PCBs
Every second, metals that form the components of our day-to-day electronics are thrown out. There are currently no efficient methods for recycling them, yet our need for these metals remains strong. Yale researchers have developed a solution that salvages metals at their "end-of-life" stage and allows them to be used once again. Megan O ...
generation by different countries, Indian scenario of E-waste, compositions of different metals in electronics components, recycling strategies, percentage recovery of precious, and heavy metals using different leaching agent including biological bacteria.
The useful life of electrical and electronic equipment (EEE) has been shortened as a consequence of the advancement in technology and change in consumer patterns. This has resulted in the generation of large quantities of electronic waste (e-waste) that needs to be managed. The handling of e-waste including combustion in incinerators, disposing ...
Shredded electronic waste with low metal concentrations is added at the start of the process, while higher concentration e-waste is added later. Zinc is removed at an earlier step with slag and then separately refined. During the refining process, precious metals such as selenium, gold, silver and palladium, are removed at separate steps than lead, and nickel. This leaves a high purity copper ...
Yet, challenges abound, and the level of difficulty and danger as well as lack of extraction resources may deter some. The most informal methods involve using harmful chemicals to extract gold as well as other precious metals from devices like computers and cell phones.
Feasibility study for the recovery of metals from electronic waste 1.0 ABSTRACT The useful life of consumer electronic devices is relatively short, and decreasing as a result of rapid changes in equipment features and capabilities.
E-waste is the shortened form of the term electronic waste and is the waste material generated from electronic products. It is also called e-garbage, e-scrap and Waste Electrical and Electronic Equipment. 
Electronic waste is usually processed by means of classical methods, i.e. in pyro- and hydro-metallurgical processes. However, new solutions for more economically and ecologically efficient recovery of metals are constantly being searched for.
This e-waste is a particularly rich source of precious metals – with concentrations 40 to 50 times more abundant than naturally occurring deposits. There are over 320 tons of gold and greater than 7,500 tons of silver used each year to make new electronic products around the world.
