Extraction of Metals Methods of Extraction of Metals
Such sources are called Ores. Extraction of metals. The process of extracting metal ores buried deep underground is called Mining. The metal ores are found in the earths crust in varying abundance. The extraction of metals from ores is what allows us to use the minerals in the ground The ores are very different from the finished metals that we see in buildings and bridges. Ores consist of the desired metal

The crust of the earth provides metals and it is a good source to procure metals. Mostly, the metals occur in nature in a combined state but sometimes they can also occur in the free state. A native metal is a metal found in its metallic state naturally, either in pure form or in the form of an alloy. Most metals cant resist natural processes like oxidation, corrosion, etc. Hence, only non reactive metals like gold, silver, platinum, etc are found in the native or free state. Most metals areRead More →

B. Extraction of Crude metal from the concentrated ore The extraction of crude metals from the concentrated ore involves the following steps Calcination In this process the concentrated ore is heated in the absence of air to a temperature below the melting points of metal. Calcination is done in a reverberatory furnace. In Calcination, a.
The process of extraction of metal from the concentrated ore depends upon the nature of the ore as well as the nature of impurities present in the ore. Before the concentrated ore is subjected to final metallurgical operations in order to get the metal in the free state, the preliminary chemical treatment may be necessary.
that contain sufficient metal to be of practical and economic use are called ores. Metals are usually extracted from ores using a combination of heating and reduction with carbon in the form of charcoal or coke. Not all metals can be extracted from their ores in this manner and may need to be extracted by a process called electrolysis.
the extraction of metals an introduction This page looks at the various factors which influence the choice of method for extracting metals from their ores, including reduction by carbon, reduction by a reactive metal (like sodium or magnesium), and by electrolysis.
