The tiny organisms then “chew up” the rock and expel the metals as waste. The metals are then piped into a refinery and separated. In nature, bioleaching is triggered spontaneously by micro-organisms in the presence of air and water. Commercial technologies modify this process so the metal can be recovered faster.
