Here, we draw on observations of the uniquely preserved El Laco iron deposit in the Central Andes to shed new light on the metallogenic role of explosive volcanism that operates on a global scale.

For every 1 ton of iron ore concentrate produced approximately 2.5–3.0 tons of iron ore tailings will be discharged. Statistics show that there are 130 million tons of iron ore discharged every year. If, for example, the mine tailings contain an average of approximately 11% iron there would be approximately 1.41 million tons of iron wasted annually. These tailings are also high in other useful metals such as copper, nickel, and cobalt, and they can be used for road-building materials

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

An explosive is a solid or a liquid substance or mixture of substances which change themselves instantaneously into a large volume of gases at high temperature and pressure when a flame, heat or sudden shock (detonation) is applied to it. The high pressure that is built up is capable of doing the work of breaking rock.
