  Gold, Silver, Platinum and Precious Metals facts

  Gold''s average concentration in the Earth''s crust is parts per million. A lower grade gold ore would contain something like 5 grams per tonne (5 parts per million). So gold ore needs to be concentrated by about 1,000 times above the average to become viable. The process of gold concentration happens both above and below the surface of the ...
