What is a theoretical graderecovery curve? An example ...
Oct 26, 2009 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 ...

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 ...

2 Hydrometallurgy is the recovery of metaIs from ores using waterbased solutions. As early as 6000 B. C., native copper–the pure metal—was foundas reddish stones in the Med iterranean area and hammered into utensils, weapons, and tools. Around 5000 B. C., artisans discovered that heat made copper more malleable.
