This experiment, designed to illustrate the simplicity of copper extraction from sedimentary-hosted mineralization, was recorded at Aurania’s Ecuadorean field office during a visit from Ecuador’s Vice-Minister of Mines, Fernando L. Benalcazar. Aurania’s President Dr. Richard Spencer shows how to go from field rocks to pure copper in a matter of minutes. Ingredients: crushed, copper-bearing sedimentary rock, a bit of sulphuric acid, a couple of nails attached to a flashlight battery with electrical wire and voila, copper extraction pure and simple.
