mining of specific surface area

Specific surface area chemeurope.com

Specific surface area is a material property of solids which measures the total surface area per unit of mass, solid or bulk volume, or cross-sectional area. It is a derived scientific value that can be used to determine the type and properties of a material (e.g. soil).

Blast performance assessment in plexiglas models by

Attempts were made at CMRI to assess the blast performance by measurement of specific surface area (SSA). This was done by conducting experiments in Plexiglas models by incorporating various blast patterns like air decking, varying stemming material, stiffness, hole size and hole deviation.

What Is Specific Surface Area? wisegeek.com

Dec 12, 2018Specific surface area is a measure of a solid object. It compares the surface area of the object to either its mass, and is particularly relevant in materials such as soil, or with materials that are theoretically a smooth surface but actually have defects such as scratches.

TC Sensitivity of snow density and specific surface area

In order to extract quantitative characteristics of the microstructure, such as the specific surface area (SSA), from these data, the greyscale image first needs to be segmented into a binary image of ice and air. Different numerical algorithms can then be used to compute the surface area of the binary image.

Mineral Extraction The Environmental Literacy Council

Surface Mining. Surface mining is undertaken when the minerals are located near the surface of the Earth. As opposed to underground mining in which the overlying rock and soil are left primarily intact and tunnels are dug, surface mining involves removing the top soil, called the overburden, in order to recover the minerals.
