Answer:

good, you dont want carbon to extract iron from iron ore, you wish to have it to make iron into metal, through reinforcing the molecular chain, to get iron from iron ore, its convenient, you soften it, scoop off the slag that floats to the highest, and bam, iron.
May it not completed, and I hope it can help you! Iron is the most widely used. Iron ore is mainly used for iron and steel industry, smelting iron and steel according to the different carbon content. The so-called iron ore deposits are the main target of industrial development and utilization. Iron ore beneficiation plant is generally divided into several stages, crushing, grinding, classification and separating. How can we design our iron ore processing plant? Maybe a professional manufacturer and supplier is one of the best choices. Before we talk about designing of iron ore processing plant, we need learn the working flow of iron ore processing first. Raw iron ore will be sent to primary crushing equipment first. In primary crushing equipment, we can crush them into small particles. After primary crushing, the secondary and tertiary crushing equipment will crush iron ores into the finesse size which is below 12mm.
A. Iron ore is generally mined from huge open pit mines using explosives, huge excavators huge dumper trucks. B. Haematite is the main iron ore produced (Fe2O3) which is easier to process than the higher iron content, magnetite (Fe3O4). Production in 2011 was estimated to have been 2,800 million tonnes. As yet unused resources are estimated to exceed 800 billion tonnes of iron ore. C. There are vast resources of iron ore particularly in Africa and Latin America which remain unexploited. D. Iron ore is used to make iron which in turn is alloyed with small quantities of other metals, in particular nickel, chromium and molybdenum to make different types of STEEL. Steel is primarily used for providing the strength in high rise building construction but is also used in motor car manufacture many other engineering applications. E. Iron ore deposits have to be very large in order to be worth mining so as to reduce the unit cost to as low as possible. F. In order to transport such vaste amounts of iron ore, from the mine to a deep water port, railways are generally constructed. At the port, the ore is transferred onto ships which then take the iron ore to their destination country (generally China) where it is smelted into iron then made into steel. G. There is work for geologists to evaluate the iron ore deposits to ensure that they mined as efficiently as possible, for mining engineers, for dumper truck drivers, for all those involved with railway construction. There is also work for ships and for those working in the construction industry in China. H. Those seeking to explore mine iron deposits in Africa, those involved with railway construction.
