Estimating Bulk Density For Mineral Resource

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 value ...

Specific Gravity and Bulk Density SGS

“Specific gravity” is the density of a material relative to water. Since rocks are comprised of several distinct mineral phases, they do not have a fixed specific gravity. Instead, a rock’s “bulk density” arises as a result of the percentage of all minerals in a sample multiplied by the specific gravity of each.

How Do You Calculate Bulk Density? - Reference

2020-3-30  Bulk density is useful for determining the density of a mixture that has many different compounds and elements in it. It is the simplest way to represent a mixture that has solid, liquid and gaseous components. Soil contains dirt, minerals, air and moisture and is usually rated based on bulk density.

Bulk Density - an overview ScienceDirect Topics

Bulk density —is the density of a volume of soil as it exists naturally, it includes air space, organic matter, and soil solids. Natural root growth is restricted as BD becomes greater than 1.5 g cm −3 in fine-textured (clay and silt) soil and at 1.7 g cm −3 in course-textured soil (sandy) ( Lyle, 1987 ).
