At these concentrations 20 or 30 tons of rock must be processed to extract a single ounce of precious gold. As a result, gold can only be mined profitably where it is highly concentrated by natural chemical and physical processes. Gold occurs in many different geologic settings and its classification into deposit types is complicated.
Silver can also be found mixed with quartz and ruby crystal formations. Silver and gold are often found together since they exist in the same base ore material.
