=>Here is ur Answer<=
Amount to 2.05 kilograms of gold 1950 kilograms of silver Olympic gold medals are about 92.5 per cent silver plated with six grams of gold and 903 kilograms of copper. A little more than 1.5 percent of each gold medal was made with metals harvested from cathode ray tube glass, computer parts, circuit boards and other trashed tech. Each copper medal contains just over one percent e-waste, while the silver medals contain only small traces of recycled electronics.
This is the first time that recycled materials have been added to Olympic medals, which historically have been made from mined mineral deposits refined for commercial use.
