Each percent increase in dilution and decrease in recovery negatively affects economic value of the reserve. These parameters are mainly controlled by the quality of the mine design and stoping practice. This study provides an approach developed for dilution and recovery/ore loss calculations.
the above equation approximates the estimated mine life 24 years because it reflects the mining reserve after dilution. the mining reserve given by company personnel at the time of evaluation was 260,000,000 st at % mos2. the data base reserves reflect this value after the recovery factor is applied and the feeds reflect the diluted grade.

Dec 10, 2018· Underground Mineral Resource is reported at a cutoff grade of g/t gold that is based on a gold price of CAD1,550 /oz. and a gold processing recovery factor of 95%. Appropriate mining costs, processing costs, metal recoveries, and inter ramp pit .
R. Garnett is the author of two related papers, |Dredge recoveries in North American placer gold mining' and |Components of a recovery factor in placer gold dredging'. Both discuss the R/E Factor, defined as the Recovered over the Expected (gold). Using historical production data, he shows that while the target average R/E factor of was ...

Recovery factor (coal) The percentage of total tons of coal estimated to be recoverable from a given area in relation to the total tonnage estimated to be in the demonstrated reserve base. The estimated recovery factors for the demonstrated reserve base generally are 50 percent for underground mining methods and 80 percent for surface mining methods.
