Usually, the process operation conditions are defined to control the balance between a high recovery of the desired metal and a high grade value of the metal in the product outflow (Méndez et al., 2009a). These processes usually include multiple stages that are interconnected (forming circuits) to maximize recovery and concentrate grade.

The theoretical graderecovery 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 graderecovery can be readily used to quickly identify potential recovery ...
