mining calculations and formulas at a gold mill

Cutoff Grade Calculation, Example 2 The operating costs for a gold mine are 55 $/ton. The recovery at the mill is 90% and the mining dilution is 10%. At a gold price of $400/oz, what is the break-even cutoff grade in oz Au/ton? One ton of run-of-mine ore at 10% dilution contains 0.9 tons of ore and 0.1 tons of waste. The mill

Calculate and Select Ball Mill Ball Size for Optimum

To accelerate the math or calculation you can use the shortened formula:Dm <= Km * d^0.5where Km =6 (log dk) is taken from Figure 5 according to the fineness of the finished product dk. These formulas are applicable to the case of feeding a mill with only single-sized balls and not a mixture without consideration for ball wear.
