    2015-12-1 · It is estimated that 1000 kg of waste mobile phones can yield about 300–350 g of gold along with other metals. The interesting fact here is that a ton of ore from a gold mine contains only about 5 g of gold (Hagelüken and Corti 2010). Owing to this fact leaching out gold and other precious metals from mobile phone waste in an environmental friendly manner has become a major research area.
