    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 25.3 Crushing and milling Mining of mineral resources,Iron ore, coke and lime are added to the top of a furnace. Hot air is blown in from the bottom. The furnace operates at a high temperature (around 1200°C). Iron ore reacts with carbon/coke to form iron metal and carbon dioxide. The iron is tapped off at the bottom of the furnace.
