Iron ore extraction techniques ScienceDirect
Iron ore was won by drilling and blasting (Figure 7.1).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 Itabira Iron Ore is created. In order to replace Brazilian Hematite, in 1911 the Itabira Iron Ore Company is organized, which receives authorization from the Brazilian government to operate. Itabira Iron Ore was headquartered in London History Center Vale
