19-2-2014Brazil hosts five of the world's biggest iron ore mines while the remaining six are located in Australia and Africa Mining-technology profiles the world's biggest iron ore mining operations based on recent estimates of proven and probable reserves
Increasing iron ore demand coupled with the depletion of high-grade hematite ores in the United States after World War II led to development of lower-grade iron ore sources principally the utilization of magnetite and taconite Iron-ore mining methods vary by the type of ore being mined
Australia's total production of iron ore for 2012 was 520 Mt with WA producing 505 Mt or 97% of overall production South Australia had a slight increase in its iron ore production from approximately 10 Mt in 2011 to 10 7 Mt in 2012 representing 2% of Australia's total iron ore production
Iron ore is a mineral substance which when heated in the presence of a reductant will yield metallic iron (Fe) It almost always consists of iron oxides the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3) Iron ore is the source of primary iron for the world's iron and steel industries
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
How to extract iron from its ore The method Three substances are needed to enable to extraction of iron from its ore The combined mixture is called the charge Iron ore haematite - often contains sand with iron oxide Fe2O3 Limestone (calcium carbonate) Coke - mainly carbon The charge is placed a giant chimney called a blast furnace The
The copper(II) ions in the chalcopyrite are reduced to copper(I) sulfide (which is reduced further to copper metal in the final stage) The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed Most of the sulfur in the chalcopyrite turns into sulfur dioxide gas
Iron ore as mined is a combination of iron with oxygen and various other unwanted substances generally known as gangue The first metallurgical step is to reduce iron ore to metallic iron a process which is mostly carried out in a blast furnace using coke as both a fuel and reducing agent
Recycling one ton of aluminum saves 8 tons of bauxite ore and recycling one ton of steel saves 2 500 pounds (1134 kg) of iron ore ton of coal and 120 pounds (54 kg) of limestone [1] By recycling one ton of steel 40% of the water used for production is conserved and 86% of air emissions and 76% water pollution are reduced [1]
