Using Low Density Explosives In Iron Ore Applications
IRON ORE MINES Dyno Nobel developed BlastLite® and TITAN® as cost effective solutions for blasting weak to medium strength rock in Iron Ore mines. The key to BlastLite lies in its ability to form a homogeneous blend without the need to use an emulsion matrix as a binding agent. The result is a low density explosive (LDE) of high

Davis of the University of Minnesota, along with other scientists and engineers, conducted years ...
Mass, Weight, Density or Specific Gravity of Bulk Materials
As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/cu.ft (pounds per cubic foot) and if we know that ammonium nitrate has a sg of 0.73 then we can calculate that its density is 0.73 x 62.4 = 45.552 lbs/cu.ft. Note, kg/cu.m divided by 16.02 = lbs/cu.ft.
