The national estimates for iron ore since 2010 are reported in two categories, namely: Million tonnes of iron ore, and; Million tonnes of contained iron. Total Australian Ore Reserves of iron ore reported in compliance with the JORC Code were estimated to be 23 106 Mt in 2018 (Table 1), representing 47% of Economic Demonstrated Resources …
Purpose In the mining industry, a run-of-mine (ROM) stockpile is a temporary storage unit, but it is also widely accepted as an effective method to reduce the short …
If a Grizzly is installed, position between two beams in a central position of the ROM Bin is always the best. Two technologies are available; Radar and Acoustic level transmitters. Both have the range capability in a dry application, but when Water Sprays are used to suppress dust, the water and dust build-up on the Radar will make it fail.

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.
