SEATTLE (Waste Advantage):At least $10bn worth of gold, platinum and other precious metals are dumped every year in the growing mountain of electronic waste that is polluting the planet, according to a new UN report. A record 54m tons of “e-waste” was generated worldwide in ...
Electronics– Silver is a natural thermal and electrical conductor and is therefore used in numerous electronics such as electrical switches, superconductors, batteries, televisions, etc. Platinum Platinum is widely considered the most practical of the precious metals, and it has been used industrially ...
The present study aimed to determine the content of precious metals such as gold and silver and one hazardous metal (lead) in selected components of e-waste (RAM and PCB of computers and mobile phones). Hydrometallurgical process was adopted in this experimental research. The results indicated ...
