  • How to Calculate Grade and Recovery with Examples ...

    What Is The Grade?What Is The Recovery?Grade and Recovery Calculation For A Jigging CircuitCalculation of Grade and Recovery For A Screening, Tabling, Flotation CircuitHead CalculationAn ore contains multiple minerals in combination; it’s a mixture of valuable components and gangue. The ore grade refers to the fraction of a useful element within the ore. It can also be used for gangue as the proportion of a non-valuable substance, but generally, when we use the term grade, we mean the grade of a valuable element. For example, a copper ore grade of 1% means that in 100 tons of the ore, we have 1 ton of copper. If tSee more on minerallurgyPublished: Mar 02, 2021
