Ore grade, the second determinant, governs the quantity of tailings generated by a beneficiation plant. An operation with ore grading 1 percent by weight, for example, will generate ninety-nine pounds of tailings for every pound of metal, assuming complete metal recovery.
Read More· In 2018, Australia''s EDR of iron ore increased by 3% from 2017 to 49 604 Mt (Table 3). Similarly, there was a 4% EDR increase of contained iron to 24 122 Mt (Table 4). EDR attributable to magnetite deposits have decreased by 1%, likely due to re-assessment of projects and inactivity in the magnetite industry.
