Extracting a metal from its ore

Metals with low chemical activity, such a gold and silver are normally found in their pure state Copper, tin, lead, and iron are more reactive and must be heated with carbon to extract the metals Aluminum, calcium, sodium and other active metals are extracted using electrolysisThe 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.

505 EXTRACTION OF METALS- METALLURGY

The process of extracting pure metal from its ore is known as metallurgy Since, the nature of the ore and also the properties of different metals are different, therefore, it is not possible to have the universal scheme which may be applicable to all the metalsMetal extraction from ores occurs in many different ways involving physical, chemical and electrical means Even ores of the same metal sometimes require different methods of separation depending on the concentration of the metal and its chemical composition within the ore.
