How do you turn electronic waste like this into gold?
如何把這樣的電子垃圾變成黃金？
The Royal Mint, whose job it is to make coins for the UK, has found a way to do exactly that. First, they take the electronic components from laptops and phones and place them in a secret solution.
英國(guó)皇家鑄幣廠負(fù)責(zé)為英國(guó)鑄造硬幣，他們找到了一種方法可以 “點(diǎn)石成金”。首先，要從筆記本電腦和手機(jī)中取出電子零部件，放入一種神秘溶液中。
The chemicals extract what’s inside and produce this brown powder. It’s then heated for 30 minutes at more than 1,000 degrees Celsius. The end result is pure gold!
這種化學(xué)物質(zhì)會(huì)提取里面的東西，從而產(chǎn)生這種棕色粉末。然后，在超過(guò)1000攝氏度的溫度下加熱30分鐘。最終結(jié)果是純金！

We’re hoping to recover all of the metals on the board. Primarily gold to start with, but we are looking at copper, nickel, tin, particularly tin, and some silver.
