    That's good For gold miners. In gold-rich ore deposits, there are concentrations of gold at one or two parts per million, That equates to 1g or 2g per tonne. And the idea that 41 handsets contain 1g of gold stems from a UN report on electronic waste. a tonne of old phones (weighed without their batteries) yields about g of gold. In the cochlear implant, the RF link(antennas present in the internal and external unit) are used for DC power supply and data transmission. So, my question is related to the data transmitted.

    Chemistry Questions & Answers: Gold and silver are extracted from their respective ores by _______.   Find waste products to extract silver from. You can contact hospitals and imaging companies or place an ad in the local newspaper to collect used film rolls, X-rays and waste photographic chemicals. (Hypo and fixers both contain silver.) You can expect to generate about grams of pure silver from each roll of exposure film.

    The Silver Extraction Process. The Silver Extraction Process. The ore used to extract silver was not a silver ore but Lead Sulphide (formula PbS), known as Galena or Galenite (named by the Roman Pliny) which contains 87% lead. The local variety of Galenite is silver-bearing and is known as Argentiferous Galenite (formula ()S) and the lead. Isolation of elements in Chemistry class 12 aims to teach the students about various processes of extraction of metals from ores. Very few metals such as the noble metals, i.e., Gold, Silver, and Platinum etc. are present in their original metallic forms in nature. Metallurgy is the field of science which deals with the extraction of metals.
