Cut-off grade estimation - QueensMineDesignWiki

In the case of multiple processing options, cut-off grade is used to determine which process or destination the ore will be sent to, by using the following equation: Where U1 is the utility of sending ore to process 1, and U2 is the utility of sending ore to process 2. Utility is defined as the value (economic or otherwise) of selecting a process.
