  • Cutoff grade estimation MineWiki, Queen's Mine Design Project Wiki

    Feb 7, 2015 The internal cutoff grade assumes that the block in question must be mined and determines whether it should be sent to the mill. The breakeven cutoff grade assumes that the block does not have to be mined and classifies the material as ore or waste to mine or ignore respectively. Both methods utilize

    The grade or concentration of an ore mineral, or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth

    Mar 24, 2017 If both of these questions can be answered 'yes' then the threshold for what constitutes 'highgrade' will be dramatically lower. As a rule of thumb, open pit mining can process ore for $10 per tonne and, where the ore grade is more than double that at $20 per tonne, results would be economic. Consider
