  • THE ANALYSIS OF THE MINE CALL FACTOR IN GOLD MINING

    The specific gravity of the ore at 2 VBOkg/m1 is overstated which results in the tonnage being overcalled as well as the grade overestimated It should be in the regior of 2700kg/m3 and can influence the gold called for by as much as ± 1C percent The combination of the aforementioned results in subsequent inaccurate estimations of the gold called for Diamond blade saws are being
