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 ...

cumulative recovery in flotation

The outcome of a kinetic batch flotation test is a series of cumulative recoveries of assayed elements as a function of time. The element recoveries are further converted to mineral recoveries. The benefit of the conversion is that the gangue kinetics can be calculated and the total mass recovery is obtained from the mineral recoveries.
