Gold Facts – 11 of the best from Chemicool

That’s 1 ounce of gold in every 264 billion gallons of water. If you could process seawater equal in volume to draining Lake Ontario, you would capture 48 kg of gold, worth less than $3 million at today’s gold price. You cannot put that amount of water – 1600 cubic kilometers – through any chemical extraction process for $3 million.
