Dump Mining In Africa Methodology

The correct measurement of dry bulk density to account for moisture content is often overlooked in tailings dump Mineral Resource estimation. Often an overly simplistic method is used to estimate the bulk density and this can cause significant errors in tonnage estimation and consequently an over estimate of metal content.
