Today, gold mining is as much about chemistry of solvents as it is about the rough physics of a shovel and pick axe. This is because today gold is now primarily found in very low concentrations—less than 10 grams per ton. Therefore, the only way to extract gold found in such small quantities is to create large open pit mines through blasting.
