In the following article extraction of iron from its ore in the blast furnace is described in light of these three quintessential steps. Extracted iron is used in Iron Extraction. The common ores of iron are its oxide, hematite, Fe 2 O 3, and magnetite, Fe 3 O 4. They can be reduced to iron by heating them with carbon in the form of coke. The coke burns in an exothermic reaction. At the high temperatures, the carbon dioxide reacts with more coke to

Extraction of Iron from oxide. Oxide ores of iron, after concentration through calcination/roasting (to remove water, to decompose carbonates and to oxidise sulphides) are mixed with limestone and coke and fed into a Blast furnace from its top. In this case, the oxide is reduced to the metal. One of the main reduction steps in this process is The process of extracting iron from ore produces great quantities of poisonous and corrosive gases. In practice, these gases are scrubbed and recycled. Inevitably, however, some small amounts of toxic gases escape to the atmosphere. A byproduct of iron purification is slag, which is produced in huge amounts.

Solution. The correct options are. A Carbon reduction of the oxide. C removal of iron impurities. D removal of copper impurities. The ore - tin stone or cassiterite contains SnO2 among many other impurities. After grinding into fine particles, the ore is washed and subjected to gravity separation. Cast iron is different from pig iron. It has slightly lower carbon content (3%) and it is extremely hard and brittle. Further Reductions-Wrought iron or mallecable iron is the purest form of commercial iron and is prepared from cast iron by oxidising impurities in a reyerberatory furnace line with haematite.

Iron Extraction Manufacturing Process - Blast Furnace Method. Iron is extracted from different ores exist in the world. Hematite (Fe 2 O 3) is reduced to iron metal in the blast furnace under several steps. Limestone and coke are used as other raw materials to generate heat and reducing agents. EXTRACTION OF IRON IN A BLAST FURNACE Iron is also below carbon in the reactivity series, so therefore carbon can be used to reduce it (note reduction can also mean to remove the oxygen from a compound). This is done in a blast furnace. The most common ore of iron is called haematite (iron(iii) oxide). Its formula is Fe 2 O 3.

One stream contains a hydrochloric acid solution of a sufficient concentration to extract iron from ilmenite and is recycled to the extraction step. The other stream contains water or a very weak hydrochloric acid solution in water and is recycled for washing the solid residue from the separation step. A process for the extraction of rare earth elements, including yttrium, from a rare earth element-bearing ore or concentrate, comprising the steps of leaching the rare earth element-bearing ore or concentrate with a lixiviant of hydrochloric acid and magnesium chloride at atmospheric pressure at a temperature of from 90C to the boiling point of the solution and at an Eh of at least 200 m V .

Cast iron is obtained from pig iron by melting pig iron with scrap iron and coke using hot air blast. It contains slightly less carbon content around 3% and it is hard an brittle. Question 6.16 Differentiate between minerals and ores. Answer Minerals are the naturally occurring substance which contains some amount of metals. Hint In the process of extraction of pure iron, from ores, cast iron is obtained from pig iron. The less pure form of the iron among these two is malleable. The iron obtained from blast furnaces has more carbon content than other types of iron mentioned in the question. Complete step by step solution - Lets see what pig iron and cast iron are.

Dec 04, 2019 (ii) Reduction of the oxide is an important step in extraction of metal. In case of iron, Fe 2 O 3 3CO 2Fe 3CO 2 Al 2 O 3 cannot be easily reduced, hence it is subjected to electrolysis. Aluminium is collected at the cathode. (iii) Iron ore contains impurities of silica and sand. These are removed by magnetic separation. One step in the manufacture of lead is the reduction of lead oxide with carbon. Lead and ... Iron ore contains the compound iron oxide, Fe 2 O 3.

The product contains about 99.5% lead, the remaining 0.5% being mostly antimony and silver with smaller amounts of other metals, including gold. Because it contains silver and gold at this stage, the lead is referred to as bullion lead. The fluxes form a molten slag of with iron reduction method 16 and the process parameters were optimized on laboratory scale to obtained maximum recovery of antimony metal. 2. Experimental Methodology 2.1. Ore Samples Stibnite ore of Kharan area of Pakistan was employed for the extraction of metal which contains 66% antimony sulfide content.
