The tonnage factor or average in-place bulk density of the orebody is one of the most important variables in the calculation of the weight of product to be expected from a proposed mining operation. Errors in the determination of the in-place dry bulk density upon which the tonnage calculations of a deposit are based may completely overshadow ...
Mineral resource and ore reserve estimates are founded on two sources of data: tonnage and grade. The tonnage is a product of volume and density; both of which are estimates. Density impacts numerous operational factors, which include, but are not limited to, mine design, mine planning, equipment selection and operational …

The incorporation of bulk density uncertainty for Mineral Resource and Mineral Reserves (MRMR) steps is of great importance for successful mine planning process. In practice, most mining projects use an average density value for each lithological type of the deposit. However, density determinations require special …
Bulk density is a critical component of the resource estimate. For mineral deposits with low metal content and simple mineralogy, calculating an average of all bulk density measurements can be adequate with sufficient data and a meaningful average. However, each geological domain must be examined individually with a separate bulk density …

significant, indicating that the changes in bed bulk density did not have a significant effect on sinter porosity. The study was then extended to include a comparable blend and two hematite blends of higher bulk density. Decreasing green bed bulk density, bed shrinkage and sinter density did not have a detri-mental effect on sinter tumble strength.
Define and explain the differences among particle density, bulk density, and specific gravity. Describe the relationship between 1) bulk density and porosity and 2) particle density and porosity. Write a mathematical expression for these relationships. What is the typical range of bulk density values for mineral soils?
The bulk density of commercially available arginine was determined by measuring the volume of known mass of powder that had been passed through a screen into a volume-measuring device, and calculating the bulk density by dividing the mass by the volume.
Tonnage and grade are the principal reported components of mineral resource estimates but tonnage is a derivative of two more fundamental estimates; volume and bulk density. Typically, most of the effort in a resource estimation study is directed towards grade and volume, yet poor application of bulk density data to resource models can result in …

Mineral resource and ore reserve estimates are founded on two sources of data: tonnage and grade. The tonnage is a product of volume and density; both of which are estimates. Density impacts numerous operational factors, which include, but are not limited to, mine design, mine planning, equipment selection and operational performance.
The bulk density values of DDGS have been shown to range from 389 to 501 kg m −3 (Rosentrater, 2006). As of now, however, there is very little known about the influence of DDGS bulk density on its flow, or the effect of storage conditions on the resultant bulk density.
This study analyzes the effect of moisture content and compression pressure on bed void fraction in different materials. The void fractions of several materials, both spherical and non-spherical, solid and porous, with different particle sizes and densities, were evaluated as functions of moisture content and compression pressure.
Rock density information is needed for the estimation of ore tonnage, and also for determining the amount of contained metal; this is because mineralisation grades are usually reported as a ratio of the economically viable components, metals or minerals, to weight units (e.g. grams/tonne). Despite the obvious importance of rock density for …
This paper presents an analysis of all forces affecting the void fraction (VF) and density of a particulate bed. The bulk density of many materials, both spherical and non-spherical, with a variety of properties, including particle size and density, were measured in air and various liquids.
Specifically, variations in soil bulk density and water infiltration rate and the influences of coal mining and vegetation type on the properties during different subsidence stages were studied at the Shendong Bulianta mine. The results showed that, in the period before mining, soil bulk density occurred in the order A. ordosica[P.
MRMR estimates using a bulk density interpolated for each block of deposit are compared with the estimates that use the simple density samples mean. Methodology In order to properly evaluate the bulk density impact in mining planning stages, two scenarios were studied and their effect on MRMR estimation was investi-gated.
