Mar 29, 2016 · Iron is a common metal known to man since history. Its chemical symbol is "Fe" derived from its Latin name Ferrum. Metallic iron is widely used as a pure metal and alloy for tools, equipment's and arms. In its elemental and oxide forms it find larger appliions in life.
Jan 16, 2019 · (a) Give two methods to prevent the rusting of iron. (b) Name the ores of the following metals: (i) mercury, and (ii) zinc (c) Explain with the help of a diagram, how copper metal can be refined ? Label the important arrangements in the experimental set up.
May 21, 2014 · All ores are minerals while all minerals are not ores as some of them might have a large amount of unwanted substances such as sand, stones and earthly impurities. For example: Aluminium occurs in earth's crust in the form of two minerals bauxite and clay. Out of these, aluminium can be easily and profitably extracted from bauxite only.
Iron is extracted from its ores by smelting the ores in a blast furnace with coke, a lowash carbonaceous residue obtained from bituminous coal, and limestone (calcium carbonate, CaCO 3), which is used as a flux to melt impurities in the ore. The product of this process is "pig iron.
The world's resources are dominated by lowgrade ore, though current world production of iron ore is largely by supply from deposits of highgrade ore composed of either rocks of massive hematite or pisolitic goethite. World iron ore production in 2013 was billion tonne, with the major producers being China, Australia, and Brazil.
From the formula, it is clear that iron and sulfur have to be removed in order to produce copper. The roasting process: changes some of the CuFeS 2 to copper oxide; removes some of the sulfur as sulfur dioxide; This is done by heating the concentrated ore from froth flotation. It is heated to between 500 °C and 700 °C in air.
Nov 04, 2019 · Ore Minerals. An ore is a natural occurrence of rock or sediment which contains enough minerals with economically important elements, typically metals, that can be extracted from the deposit economically. The ores are extracted by mining for a profit from the earth; they are then refined (often by smelting) in order to extract the valuable ...

Give reasons for the following: (i) Carbonate and Sulphide ores are usually converted into oxides during the process of extraction of metals. (ii) Ionic compounds have generally high melting points. (iii) Hydrogen is not a metal, but it has been assigned a place in the reactivity series of metals.
This is similar to the porosity values of the commercial lump iron ores used in the blast furnace (% for MBR Brazil iron ore) and the direct reduction processes (–% for Orissa India iron ores) . Furthermore, sample Ug5, whose chemical composition is similar to that of samples Ug14 had a higher porosity value of %.
Cast iron has already been mentioned above. This section deals with the types of iron and steel which are produced as a result of the steelmaking process. Wrought iron. If all the carbon is removed from the iron to give high purity iron, it is known as wrought iron. Wrought iron is quite soft and easily worked and has little structural strength.

A METAL ORE is a mineral or mixture of minerals from which economically viable amounts of metal can be obtained. Two important ores to know: 1. MAKING IRON in the blast furnace. (A) List and describe the four principal raw materials (including air) which are used in the blast furnace. Carefully explain the function of each raw material used.
Oct 28, 2021 · The amount of iron oxide copper gold ore is about 10 million to 4 billion tons. IOCG ore contains copper with a grade of % to 5% and gold with a content of to grams per ton. Iron oxide copper gold ore tends to be conical on the edge of granite, or appears as long banded breccia or massive iron oxide ore in faults or shears. Brief ...

Jan 12, 2020 · History . Iron was likely originally discovered and extracted as a result of wood burning on top of ironcontaining ores. The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (presentday Iraq) between 2700 and 3000 BCE.
