Hoffman's Formula As initially developed, his formula is intended for .308 Match Cartridges, either the 168-gr. BTHP round, or its cousin, the 175-gr. round. His formula has three basic steps: 1. Make an accurate range estimate and preliminary wind speed calculation as if it were a 10 MPH full-value wind 2.

fractions. The long residence time of the gold within the grinding circuit can cause some of the GRG to become non-gravity recoverable due to smearing on to grinding media, mill liners and gangue minerals. This effect is minor as more than 98% of the GRG entering the ball mill remains gravity recoverable after grinding (LaPlante, 2000).

As a result, the copper and gold net smelter returns for copper concentrate sold to Smelter A are equal to $511 and $515 per tonne of concentrate, or $48.01 and $48.37 per tonne of ore. When these numbers are divided by the mill feed grade, the copper and gold NSR factors are equal to $20.69 per % Cu and $18.97 per gram of gold.
