In 2013, an estimated 1.2 billion metric tons of coal were used by the steel industry. China is the world's largest producer and consumer of coking coal, accounting for about 527 million metric tons in 2013. Australia and the United States follow, producing 158 million and 78 million metric tons, respectively.

Coal does three things in this process: it is burned to supply the huge amounts of heat required, it supplies gases to strip oxygen from the iron ore and roughly 1% of the coal ends up as carbon in the steel. …
From the data in Table 1 and Fig. 3 it is apparent that the production of hot metal or pig iron is the most energy intensive process for steel production at roughly 13.5 × 10 9 joules per ton (1000 Kg) of pig iron produced. The basic oxygen furnace is the second most energy intensive process at 11 × 10 9 joules per ton or steel produced. The Electric arc furnace …

Steel is produced via two main routes: the blast furnace-basic oxygen furnace (BF-BOF) route and electric arc furnace (EAF) route. The BF-BOF route is used for 71% of steel produced, whilst the EAF route accounts …
Metallurgical (met) coal (or coking coal) is a naturally occurring sedimentary rock found within the earth's crust. Categories of met coal include hard coking coal, semi-hard coking-coal, semi-soft coking coal and pulverised coal for injection (PCI). These apply to the different quality grades of met coal, all of which are used to make steel.

Metal Recycling Scarp. Today, it is estimated that the global steel industry used about 2 billion tonnes of iron ore, 1 billion tonnes of metallurgical coal and 575 million tonnes of steel scrap to produce about 1.7 billion tonnes of crude steel. Recycled steel (also called scrap steel) is one of the industry's most important raw materials.
how much coal it takes to make 1 tonne of iron Mining. Nov 18, 2012· How much iron ore it takes to make 1 tonne of steel? Runescape Answer: You would need around a 1000 iron and 1000 coal. 1 Steel = 1.81kg »More detailed. steel production, coking coal World Coal Association. How many tons of iron ore is required to produce 1 ton of sponge
Steel is around 95% Iron. Steel is around 95% iron. The amount of iron ore it takes to produce 1 ton of steel is dependent on the iron content of your iron ore. The most heavily referenced iron ore indices (TSI, Platts) take to a 62/63% iron ore standard. Primitive Skills; Making Steel From Iron Ore.
Extrapolated, this theoretically displaces 22.5 million tonnes of coke (equivalent to around 33.75 million tonnes of metallurgical coal, as it takes about 1.5t metallurgical coal to make 1 tonne of coke). For context, Australia currently supplies around 200 million of the worlds 320 million tonnes of metallurgical coal.
