Open-pit mining is probably most advanced because of developments in mining low-grade copper deposits and iron ore. It is suitable for much of the resource if it is done on a large scale and will allow low-cost removal of most of the resource.

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...

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 progressed to the dip, this ...
