Ore grade number refers to certain metals useful components contained in the ore, generally expressed as a percentage (%). Some use gram per ton or cubic meter of ore expressed in grams per gram (g / ton), (g / m3 ). Such as the grade of gold ore, the gold ore is expressed in grams / ton, sand gold is commonly used "g / m 3 " to indicate the grade of ore. The ore grade should be obtained by sampling test results.
In the process of mineral processing , it is necessary to constantly grasp the changes in the ore grade, concentrate grade and tailing grade, in order to better analyze the problems in the ore dressing production.
Product grades are usually expressed in Greek letters: alpha (read alpha) for ore grade; beta (read beta) for concentrate grade; θ (read west) for tailing grade.
