Occurrence of Metals: Metal Ores, Methods of Extraction

Occurrence of MetalsOresGangue Or MatrixExtraction of MetalsSolved Example For YouThe 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 can’t resist natural processes like oxidation, corrosion, etc. Hence, only non-reactive metals like gold, silver, platinum, etc are found 在toppr上查看更多信息

The metals at the bottom of the activity series are least reactive. They are often found in free state. E.g. Gold, silver, and copper. But copper and silver are also found in combined state as their sulphide or oxide ores. E.g. copper which is found as Cu2S in nature can be obtained from its ore by just heating in air.
