Precious Metal Extraction from Electronic Components
|Printed Circuit Boards, Connectors and Components have high levels of precious metal content. Chemical extraction of gold, silver, platinum, palladium and rhodium can be extracted from such components.Removal and disposal of hazardous materials including Mercury, Cadmium, Beryllium Oxide and Batteries (NiCd, Lithium etc.) is also undertaken.Elements found in trace amounts include americium, antimony, arsenic, barium, bismuth, boron, cobalt, europium, gallium, germanium, gold, indium, lithium, manganese, nickel, niobium, palladium, platinum, rhodium, ruthenium, selenium, silver, tantalum, terbium, thorium, titanium, vanadium, and yttrium.
Almost all electronics contain lead and tin (as solder) and copper (as wire and printed circuit board tracks), though the use of lead-free solder is now spreading rapidly.
