Gold plated circuit board
Notice the gold dotting this connector board, making it a very valuable (and heavy) piece of equipment to recycle. There's gold in ordinary cell phones, along with copper and silver, and the gold is easy to extract. Cell phones yield up to 150 grams (15.3 ounces) of gold per ton, compared to five grams per ton of ore, according to Urban Mining.
