Concentrate Grade
where C is weight of concentrate (or more precisely flowrate, e.g., t h −1), F the weight of feed, c the grade (assay) of metal or mineral in the concentrate, and f the grade of metal/mineral in the feed. Provided the metal occurs in only one mineral, metal recovery is the same as the recovery of the associated mineral. (Example 1.2 shows how to deal with situations where an element …

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 …
