Sep 08, 2013  C = F/K = F (f — t) / (c-t) = the weight of the concentrate. Recovery % Represents the ratio of the weight of metal or mineral value recovered in the concentrate to 100% of the same constituent in the heads or feed to the process, expressed as a percentage. It may be calculated in several different ways, depending on the data available.

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 ...

Minimizing of fines and slimes during a grinding circuit is a routine task for successful processing and the increase of recovery. Ordinarily, the replacement of hydrocyclones and classifiers by vibratory screens is recommended for the recovery of friable, brittle, and heavy minerals (for example scheelite) in modern mineral processing plants.

designed and operated plants. This represents a gold recovery of 90–99% depending on the tenor of the feed solution. These high recoveries are achieved because the carbon is transferred countercurrent to the main pulp flow. Transfer is normally accomplished by pumping pulp and the associated carbon in a countercurrent direction. Due to the ...
