Minerals recovery from the earth's crust and the subsequent processing of economic mineral deposits, ie, ores, constitutes a wide variety of steps.

What is a theoretical grade-recovery curve? An example ...

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 ...

THEORETICAL Limiting Grade Recovery Curve

To generate a limiting grade-recovery curve, three points are shown for each mineral. The left most end point of the curve represents the feed grade of the composite. The middle point of each curve represents the concentrate grade produced when all of the particles bearing target mineral are recovered. The far right end point represents the concentrate grade and recovery
