In November 2011, the lower house of the Australian Parliament passed the Mineral Resource Rent Tax (MRRT), which replaced the previously proposed Resource Super Profit Tax (RSPT) and would require a tax of 30% on profits above certain levels from coal and iron ore mining starting 1 July 2012. The Senate is due to debate the bill in 2012

Mar 01, 2016 In the ironmaking process, the blast furnace process extracts iron from crude iron ore (Fe 2 O 3) by heating the ore and melting the metal fractions to liquid pig iron. An efficient reduction reaction is required, in order to extract the O 2 from the iron ore. This is achieved by adding a reducing agent, usually coke, to the blast furnace

Oct 10, 2017 Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities. The iron ore is dressed or crushed into 0.5-1 in. chunks, which increases surface area for reactions. Magnetic separation is used to remove some of the undesirable minerals or gangue in the crushed ore
