Oct 25 32 The Lake Grassmere salt works in Marlborough produces the metal compound known as sodium chloride from ‘salty’ seawater Metals can be produced smelted from their ores by a variety of methods Aluminium is produced from its ore bauxite by passing a very large electric current through a molten mixture of the ore and a compound called The process of extracting the metals from their ores and refining them is calledmetallurgy The choice of the process depends upon the nature of the ore and the type of the metal The metal content in the ore can vary depending upon the impurities present and chemical composition of the ore Some common steps involved in the extraction of
اکنون پرس و جوMetals and their Us Like woods each metal has its especial uses and it will depend largely on what you are going to make as to the kind of metal you should make it of There are five chief metals and a couple of alloys which are formed by melting and mixing two or more metals together which you will find the most useful and I shall Aug 02 32 Steel and alloys top the list for overall strength Steels alloys of iron and other metals are much harder than any one type aloneThe following are the strongest metals in the world Carbon Steels have a carbon content up to 21 percent by weight a yield strength of 260 megapascals MPa and a tensile strength of 580 MPaThey score about 6 on the Mohs scale and are extremely impact

اکنون پرس و جوThe metal ores that are found in veins within plutons typically occur a by themselves as pure mineral assemblages b together with other ores but with no other minerals c alongside abundant calcite d alongside abundant quartzSome different types of ores and their uses are bauxite which contains aluminum stibnite which contains antimony chromite which supplies chromium chalcopyrite which provides copper and wolframite and scheelite which provide tungsten
اکنون پرس و جوHow do we extract reactive metals that cannot be obtained using carbon Why do we need to use electrolysis to obtain certain metals from their ores eg how do we extract aluminium from its bauxite ore containing aluminium oxide How do we extract sodium from salts like sodium chloride All the electrolytic process are described complete with the electrolysis electrode equationsHematite is sometimes found in vein like deposits which are not usually large enough to be important Such ore bodies have been found near Kitchener BC and in the Matachewan area Ontario Deposits of considerable size have been found at the contacts of igneous intrusions generally basic with crystalline limestone dolomite and limey shale the ore is usually of the specular variety and
اکنون پرس و جوIsolation of elements in Chemistry class 12 aims to teach the students about various processes of extraction of metals from or Very few metals such as the noble metals ie Gold Silver and Platinum etc are present in their original metallic forms in natureNov 21 32 Below is a summary of the most common heavy metals their sources and the burden they add to the human body as provided by Doctor’s Data IncDoctor’s Data Inc DDI is a premier clinical laboratory with over 30 years experience that specializes in essential and toxic elemental testing
اکنون پرس و جوMetals react differently with different substanc It gives a descriptive detail on metal reactions with the extraction of metals from ores and with acids and water In other words the most reactive metal is presented at the top and the least reactive metal at the bottom The ore grade or concentration of an ore mineral or metal as well as its form of occurrence will directly affect the costs associated with mining the ore The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore
اکنون پرس و جوGeochemical exploration relies on the fact that metals in ore deposits will undergo dispersion by weathering erosion and transport process A geochemical anomaly is a concentration of metal above its normal background value A dispersion occurs when small amounts of metals are spread out around the ore deposit by surface processApr 13 32 What metals are extracted by electrolysis What is a metal that is extracted by the process known as electrolysis Extraction from the metal ore involves reduction of the metal and electrons can reduce any metal ion This can be seen in isolating copper compound from its ore An ionic compound is dissolved with an appropriate solvent
اکنون پرس و جوJun 02 32 Best Answer Same as the old method reduction smelting Iron is found oxidized so you need to steal those oxygens You do this by adding coke purified carbon from coal to iron and heating The carbon grabs the oxygen becomes CO and CO2 the iron reduces to An ore is usually a compound of the metal mixed with impuriti When the metal is dug up a method must be used to separate the metal from the rest of the ore This is called extracting the metal The method of extraction depends on how reactive the metal is The more reactive the metal the more difficult it is to extract from its compound
