How to Calculate Grade and Recovery with Examples

2021-3-2  Grade and recovery are the most critical parameters in mineral processing. When we concentrate ore by a single process or a flowsheet of processes, we need to calculate both grade and recovery to ensure the operation’s success.

What is a theoretical grade-recovery curve? An

2009-10-26  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.
