In a 10 year period, the gigantic Consolidated ia Mill processed over 800,000 tons of gold and silver ore worth around sixty million dollars. This description of the amalgamation process is very simplified as I have failed to mention many other steps and equipment (see the epilogue for a first person account of a milling setup).
