Top five iron ore producing companies of the world

01.09.2020  Pig iron for the manufacture of steel accounts for 98% of all iron ore production, with about 1.6 tonnes of the material needed to manufacture one tonne of the alloy. Comprising nearly 5% of the earth’s crust, iron ore is mostly found in the form of haematite (which gives out the reddish tint in iron ore) and magnetite (lodestone).

01.01.2015  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 ...

Iron Ore Mining Techniques Metal Extraction

These ores can extract iron by heating them with the carbon present in the coke. Heating coal in the absence of air produces coke. Coke is cheap and acts as the heat source and is also the reducing agent for the reaction. Hot air is blown into the bottom of the furnace and heated using the hot waste gases from the top at a temperature of about 2200K. It is important to not waste any heat ...
