    This free concentration of minerals can be seen as an “avoided cost” with regard to mineral processing and refining. When high-ore-grade mines are depleted, as is currently happening,there is a reduction in this free bonus. This leads to extensive exergy consumption for extracting a similar quantity of metal from a lower-ore-grade mine.
