Underground mining (hard rock) - Wikipedia

Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies. Soft rock mining refers to excavation of softer minerals such as salt, coal ...

Direct Reduced Iron (DRI) - Cargo Handbook - the .

Direct-reduced iron has about the same iron content as Pig Iron, typically 90–94% total iron (depending on the quality of the raw ore) as opposed to about 93% for molten pig iron, so it is an excellent feedstock for the electric furnaces used by mini mills, allowing them to use lower grades of scrap for the rest of the charge or to produce higher grades of steel.

Air classifiers - Metso

Centrifugal air classifiers use secondary air flow to separate particles ranging from 100 microns to 20 microns. This air flow, as well as the diameter of the coarse-particles opening, is adjustable – for a clear, accurate cut point. Secondary air flow is also crucial in the removal of near-size particles.

The dry process technologies combined produced a high-grade magnetic product of 62.00% Fe from a raw feed containing 54.55% Fe and yielded 71.56% by mass with around 82% iron units. This was achieved by considering 16.11% of the mass as rejects (air classifier fines and IRMS non-magnetics products) which included the main impurity units such as SiO2 (24.13%), Al2O3 (22.68%), TiO2 .
