How scrappers cash in on gold from your old computer

One ton of circuit boards from old e-waste can contain 100 times more gold than a ton of ore mined from the ground. Now, scrappers like Wade Cawley in Sydney, Australia, are cashing in. He’s partnered with Mint Innovation, a company that invented a safer and cleaner way to recover precious metals from electronics. In one day, Mint can salvage up to $85,000 in gold from recycled electronics.
