Each of the holes is detonated just a millisecond apart, resulting in a pile of crude iron ore that is broken apart to a minus 2 m x 2 m size. The wide holes in the ground created by drilling, blasting, and ore removal are referred to as 'open pits'. Following blasting, the fractured ore is known as run of mine (ROM) ore.

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.

Such stockpiles will only grow as large as the operator allows them to grow. At any time the operator can process the material and deplete the stockpile. Be aware that mining operations might still be mining other ore types, then those ores may need to be stockpiled during the campaigning. That means even more ore stockpiles at site. 2.

About ore blending & stockpiles: Since the function of the stockpile is to act as an ore reservoir rather than as an ore processor, the action of forming a stockpile should have as little effect as possible on the material. Several undesirable effects are produced by discharging the material from too great a height above the stockpile.
