How do we extract minerals? U.S. Geological Survey

Large tabular-shaped ore bodies or ore bodies lying more than 1,000 feet (300 m) below the surface are generally mined underground as well. The rock is drilled and blasted, then moved to the surface by truck, belt conveyor, or elevator. Once at the surface, the material is sent to a mill to separate the ore from the waste rock.

Iron ore extraction techniques - ScienceDirect

2015-1-1  Iron ore was won by drilling and blasting ().As mining technology generally developed, so did drilling techniques and the explosives used. Smith (1990) reported that the Cleveland deposit was associated with a very strong stone roof rock (known as “dogger”) allowing mine drivages to be self-supporting. However, he states that in later years where the mining had

How is Iron Extracted from Iron Ore Actforlibraries

The iron ore itself is not pure ore. It is also contaminated with a variety of rock, which will not necessarily melt at blast furnace temperatures and therefore could clog it up. For this reason, limestone, or calcium carbonate, is added to the initial furnace charge. The hot furnace reacts with the limestone to give calcium oxide.
