Iron ores are rocks and mineral deposits from which clanging iron can be reasonably extracted Iron ore mining is classified into two categories- manual mining and mechanized mining methods Haematite and magnetite are the most commonly found iron ore minerals Deposits of iron ore such as haematite containing iron oxide are found in sedimentary rocks from which the oxygen is removed from the .
Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide
On average the production of one tonne of steel results in 200 kg (EAF) to 400 kg (BF/BOF) of co-products These include slags, dusts, sludges and other materials Ironmaking and steelmaking slags More than 400 million tonnes of iron and steel slag is produced each year Slags are a mixture of silica, calcium oxide, magnesium oxide.
This partly explains why the average efficiency of the iron and steel industries in China, India, Ukraine and the Russian Federation are lower than those in OECD countri These four countries account for nearly half of global iron production and more than half of global CO2 emissions from iron and steel production
46) Limestone is added to the iron producing mixture in a furnace to A) add carbon to the mixture B) provide an additional reducing agent to extract all of the iron from the ore C) combine with silicates to remove impurities in the form of a slag D) produce a more corrosion resistant iron
