why gold is used in sim
how much gold will come out of sim card
But a very small amount of gold is present in the SIM card. If you collect thousands of SIM cards and extract gold from them, then only a few grams of gold will be extracted from them. In such a situation, it is not going to be a profitable deal. The process of extracting gold from the same SIM card is also very complicated. However, together with Angela Serpe and Paola Deplano, they have found an easy way to extract gold from the SIM card. She works at the University of Cagliari, Italy.
what will be the advantage of it
Gold can not only be recycled by the process of extracting gold from the SIM card. Rather, the e-waste of the SIM card can be disposed of. With this, medical devices can be made, due to which the cost of medical devices will come down. Extracting gold from the same mine will help to some extent in preventing damage to the environment.
