A lot of people have begun to sell their phones on after they have finished with them. Often, this is via the use of recycling websites such as Envirophone and Mazuma Mobile (there are many more) or even a highstreet store like Albemarle Bond. Now people are also starting to sell their mobiles on to get the value of the small amount of gold that can be used in the phones. Recycling your old phones can be useful in many ways. They can be taken apart and their various bits and pieces used to make other things. It also means you come away with a little extra cash in your pocket while being a lot more economical.
Gold can be used for micro voltages as they are a highly conductive metal – hence their use in a lot of things. One of the best uses of gold is that they don't corrode very easily, meaning the demand for it is a lot higher than you would think. The very small percentage of gold put into each mobile phone seems a minuscule amount, but put all this gold together, and there is a vast amount. Around one billion mobiles are made every year, each of them containing around 50 cents in gold. A lot of these aren't recycled, so it is a waste of the gold (and money) in this respect.
Gold is one of the most important of metals in the industrial sector, particularly when it comes to electronics. Devices such as our mobile phones use such little currents and voltages and gold is the conductor used to try and carry the currents around your mobile and stop the corrosion from happening. This also means they are a lot more reliable. Devices such as televisions and calculators also have a bit of gold in them. You can also recycle these electronics although there aren't as many services readily available to do so.
