e-waste or e-scrap (electronic waste and scrap) is an actual gold and silver mine for those who wish to reclaim their precious metals values! e-waste is extracting gold from e-waste: step by step guide for beginners: extraction of gold from e waste [pennie, cherlyn] on amazon.com.
the metal recovery was performed using cementation, precipitation, ion exchange and carbon adsorption. sheng and etsell (2007) extracted gold from computer
in order to extract gold from electronic waste, first, unwanted elements must be removed from the combination. thus, copper, silver, and
right now the urban mining of precious metals from e-waste is largely an to extract copper, gold, silver and other precious metals.
there are two standard methods for extracting gold from electronic scraps: burning off the gold using high temperatures, which is energy
also e-waste contains precious metals like gold, silver, copper, selenium, mercury etc. many of these products can be reused, refurbished, or recycled.
one tonne of e-waste contains more gold than 17 tonnes of ore, making it a rich alternative to traditional mining.
