  Thinking of throwing your old cell phone?Think again.Maybe you should mine it first for gold, silver and other metals.It’s called“urban mining”, searching through the small pieces of metal in electronic products for gold, silver and other expensive metals.It is a growing industry around the world as prices for metal grow higher and higher.

  The gold and other precious metals from electronic products are melted down and then sold.The metals can be made into jewelry or circuit(电路)for mobile phones.“It can be precious, so we want to recycle whatever we can,”said Tadahiko Sekigawa, president of Eco-System Recycling Co.Ltd.

  A ton of ore(矿石)from a gold mine produces just 5 grams of gold on average, while a ton of mobile phones can give 150 grams or more, according to a study by Yokohama Metal Co-Ltd., another recycling company.The same amount of useless mobile phones also contains around 100 kg of copper and 3 kg of silver, among other metals.

  Recycling has become more important because prices of metals have hit record highs.Eco-Systems, opened 20 years ago near Tokyo, usually produces about 200 to 300 kg of gold bars a month, worth about $5.9 million to $8.8 million.That’s about the same as a small gold mine.
