The amount of tailings generated is dependent on the ore grade, (proportion of valuable minerals in the ore). For example, if the cut-off grade in the ore is 1 % Copper, 99 percent of the total ore would be deposited as tailings. Iron ores generally have higher grades than sulfide or gold ores, often going over 50 per cent or more.
