 javamanjoe rated 5 months ago- TURNING GARBAGE INTO GOLD MINDS. COOL. Thinking of throwing out your old cellphone? Think again. Maybe you should mine it first for gold, silver, copper and a host of other metals embedded in the electronics - many of which are enjoying near-record prices.

- From the page: "A tonne of ore from a goldmine produces just 5g (0.18 ounce) of gold on average, whereas a tonne of discarded mobile phones can yield 150g or more, according to a study by Yokohama Metal, another recycling firm."

- "The gold and other precious metals are melted down and sold as ingots to jewellers and investors as well as back to manufacturers who use gold in the circuit boards of mobile phones because gold conducts electricity even better than copper."

- Urban mining of cell phones and other objects with precious metals. It's like having a small gold mine.
 Tyrhaynes rated 5 months ago- What kind of tripe is this! Will people continue to fall for the recycling myth and extraordinarily bad science?
Best conductors in order: Silver, copper, and in third place...gold.
Barring Governmental subsidies the only recycling program that works well without prohibitive external costs (such as toxic waste byproducts for paper recycling) are aluminum cans, rechargeable batteries, and printer ink cartridges.
In a century or two there might be a real scarcity of metals but at the moment there is a false scarcity created by mining companies who limit their production to maintain higher prices and ignore mines full of copper because they would cost too much money to extract with "industrialized nation" labor wages. Think of it as similar to the rolling black outs and brown outs in California that Enron and Co created to increase electric prices by operating the plants at below full functionality.

- As the scarcity of metals starts to bite we must reconsider what we waste. This article shows clearly how we can not only curb waste but also adopt a real attitude to sustainability. Planet Earth can cater for our needs if we simply learn some very basic lessons.
