wt% copper, 004 wt% gold, 015 wt% silver, and 001 wt% palladium The extraction of these metals from PCBs is both profitable and environmentally worthwhile Hence, this study aims to design a commercial process to extract these four metals from PCBs of computers and mobile phones This paper discusses the relevantLater, the gold can be collected and recycled Methods currently used to extract metals involve toxic solvents and cremation and, therefore, release harmful substances into the atmosphereNew Technique Extracts Gold From Discarded SIM Cards

Extraction of Gold

When the gold has solidified, the molten silver chloride collected on the surface is run off, carrying with it a small proportion of gold When silver is the chief impurity in the gold, as in that found in Australia, the process is specially applicable The gold has a degree of purity of 991 to 997 per centGold Processing Methods & Gold Ore Extraction Of all the methods of extracting gold & processing it from its ore, I used a few to evaluate two principalGold Processing Methods & Gold Ore Extraction
