The ore grade or concentration of an ore mineral or metal as well as its form of occurrence will directly affect the costs associated with mining the ore The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth miningSeparation and recovery of iron from a low grade carbonate bearing iron ore using magnetizing roasting followed by magnetic separation Jianwen Yu Yuexin Han
