Using Low Density Explosives In Iron Ore Applications

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 weight strength compared to existing LDE products, offering a powder factor reduction compared to ANFO of around 25 per cent in the process

Iron ore Wikipedia

Usable iron ore production in million metric tons for 2015 The Some chemicals are deliberately added such as flux which makes a blast furnace more efficient. Others are added because they make the iron more fluid, harder, or give it some other desirable quality. The choice of ore, fuel, and flux determine how the slag behaves and the operational characteristics of the iron produced

PRIMING OF EXPLOSIVES FOR EFFICIENT BLASTING

14/05/2013· PRIMING OF EXPLOSIVES FOR EFFICIENT BLASTING By: Partha Das Sharma 1. INTRODUCTION: The massive use of blasting agents such as ANFO, Heavy ANFO etc., in rock breakage has brought about an important development of initiation and priming techniques. This is due to, on one hand, the relative insensitivity of these compounds and, on the other

How is Iron Ore Mined Pediaa.Com

Mining of iron ore can be manual or it can be mechanized depending upon the size of the mine and the reserves of iron ore to be extracted. Drilling is carried out with the help of giant drill blasters and then explosives are placed inside the holes to remove the overburden. These explosives are usually gunpowder and gelatin cartridges. The iron ore that is blasted is stacked and loaded upon
