Similarly, if the purest mineral grain that contains the metal of interest is removed, this will be the maximum grade that can be produced by a physical separation, and so the 0% recovery end of the curve terminates at an assay less than or equal to the assay of the purest grains available in the ore

    What is a theoretical grade-recovery curve? An example

    Oct 26, 2009 The theoretical grade-recovery curve for an ore is a definition of the maximum expected recovery by flotation of a mineral or element at a given grade. This is defined by the surface area liberation of the value minerals and is consequently directly related to the grind size utilised in the process. The theoretical grade-recovery can be readily used to quickly identify potential recovery

    How to Maximize Grade and Recovery Curve- Case of

    Generally, we plot the grade and recovery in the form of a curve to illustrate their dependence variation among the process. The maximum recovery is 100%, which refers to the raw material or the ore before beneficiation. But the ultimate grade of a substance in the ore is its value in the pure mineral. For example, the lead grade in PBS is 86
