Advantages of equations for extraction of iron

extraction of iron (examples, answers, activitiesiron oxide + carbon monoxide iron + carbon dioxide fe 2 o 3 + 3co 2fe + 3co 2. iron from the blast furnace is an alloy of about 96 per cent iron with carbon and some other impurities. it is hard, but too brittle for most uses. so, most iron from the blast furnace is converted into steel by removing some of the carbon. show videoextraction of iron flashcards and study sets quizletbrowse 6 sets of extraction of iron flashcards. study sets diagrams classes users. terms. ic3dew. extraction of iron. hot air, limestone, coke, iron ore. source of oxygen. reacts with impurities and removes them. form of carbon, displaces the iron.roasting (metallurgy) roasting is a process of heating a sulfide ore to a high temperature in presence of air. it is a step of the processing of certain ores.more specifically, roasting is a metallurgical process involving gassolid reactions at elevated temperatures with the goal of purifying the metal component(s). often before roasting, the ore has already been partially purified, e.g. by froth flotation.international gcse chemistry pearsonmay 29, · 2 iron and aluminium are two important metals extracted from their ores on a large scale. (a) in the extraction of iron, three different raw materials are put into the top of a write the two ionic halfequations that can also be used to represent this extraction.
