Iron Mining in the 1890s used drilling and blasting to loosen extremely hard iron ore (drilling was also used to locate the ore) in the open pit mining process. A compressed air drill with a diamondtipped bit was used to bore holes three inches in diameter and about four feet deep; the holes were then filled with dynamite or nitroglycerin and the explosives detonated.

Produced from the direct reduction of iron ore (in form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. Directreduced iron is richer in iron than pig iron, typically 9094% total iron, as opposed to about 93% for molten pig iron, and 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.
