Precious metals are metals that are resistant to corrosion and the oxidizing effects of moist air. The price of precious metals is typically high, mostly due to their rare occurrence in the earth’s crust.
Precious metals, in addition to being chemical elements, are a group of rare metals that have a high (economic) value. They are less chemically reactive than the other elements. They are brighter, more glittery, softer or more fictile, easier to shape. They have a higher melting point compared to other metals. Historically, precious metals have been of great importance as money (as a currency), but today they are most important as investment and industrial commodities.
Gold is one of the most popular precious metals and the second best power line, which is why it is suitable for making circuits and motherboards. Although the separation of gold from their electric gadgets is still carried out by a chemical process, a study by Truecost * also shows that recycling is still 99% more environmentally friendly than extraction from mining. A ton of used motherboard contains 800 times more gold than a ton of gold ore. In e-waste recovery factories, copper is used to extract gold, silver, palladium, platinum and rhodium, and lead is used to extract bismuth, indium, selenium and tellurium.
Our company extracts all reusable precious metals from e-waste and after cleaning, re-markets them.
