    Ore grades as little as 0.5 parts per million (ppm) can be economical. Typical ore grades in open-pit mines are 1–5 ppm; ore grades in underground or hard rock mines are usually at least 3 ppm. Because ore grades of 30 ppm are usually needed before gold is visible to the naked eye, in most gold mines the gold …

    The rock is then dumped into an ore bin until being fed through ore bin gates into an ore feeder , then into the stamp mortar. When the rock runs through the stamp battery, the finely crushed mixture is washed over a series of copper plates coated with mercury (amalgamation tables) where the freed gold combines with the mercury to form what is called amalgam (the process of amalgamation).
