### effect of bulk density bulk density on ore mining

effect of bulk density bulk density on ore mining THE IMPORTANCE AND TESTING OF DENSITY / 3.3 Bulk Density by measurement For uniform rectangular refractory shapes the simplest way of measuring Bulk Density is by dividing Dry Weight by Bulk Volume which is calculated from measured dimensions.

More### effect bulk density bulk density on ore mining

Bulk density is a measure of mass per unit volume of ore in which pure barite has a density of ~4.5 g/ml compared with quartz which has a much lower density Bulk samples may be obtained if trial mining or production is already in progress at a site.

2012-9-12 The bulk density plays an important role on mine tonnage estimates as well as on the grade estimates. A current practice consists of using an average bulk density over a given geological domain or lithotype determined from a few samples collected from it. This practice has shown that for long-term reconciliation the expected tonnage is similar to the obtained tonnages. Conversely, for short-term
