Zinc processing, the extraction of zinc from its ores and the preparation of zinc metal or chemical compounds for use in various products. Zinc (Zn) is a metallic element of hexagonal close-packed (hcp) crystal structure and a density of 7.13 grams per cubic centimetre. It has only moderate
Extraction of Iron quiz for 10th grade students. Find other quizzes for Chemistry and more on Quizizz for free!
The first step in the production of steel or cast iron alloys is the reduction of iron ore, which contains iron oxide and gangue or mineral impurities, to unrefined hot metal or pig iron. The blast furnace is currently the key tool for ironmaking.
Iron processing - Smelting, Refining, Alloying: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron …
The primary product of the smelting process outlined above is a carbon-saturated ferroalloy containing 76 to 80 percent manganese, 12 to 15 percent iron, up to 7.5 percent carbon, and up to 1.2 percent silicon. It can be produced by two methods.
The high contents of iron and calcium in the zinc extraction residue make both elements necessary for the iron ore sintering process. This similarity in chemical composition presents a promising method for treating zinc extraction residues through the iron ore sintering process.
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 steel-making 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.

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.
Iron extraction is an extremely important process as it deals with building a bridge, house et cetera. Iron extraction is one of the main parts of metallurgy. Iron Extraction Procedure. Iron extraction is considered as an extremely lengthy process that starts from concentration and ends through calcination roasting.
If another extraction is to be done, return the bottom layer to the conical vial, add fresh solvent and repeat the extraction and separation.

Prof. Robert J. Lancashire ( The Department of Chemistry, University of the West Indies) The Extraction of Iron.
In the smelting reduction process, pelletized iron oxide ore or fine ore powders are pre-reduced in a fluidized bed or reduction shaft. The reduced iron along with coal and lime is fed to a gasifier-melter, which completes the reduction process and produces pig iron or hot metal of the same quality as a blast furnace.
Iron processing - Ores, Smelting, Refining: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and …
