Cutoff grade estimation QueensMineDesignWiki

Mineral Classification. Cutoff grades are used to determine the point at which material becomes economically valuable. Therefore, they are necessary to define the amount of ore in a deposit. The classification of ore depends entirely on cutoff grade. Increasing the cutoff grade places a stricter requirement on what can be considered ore.
