Occurrence of Metals: Metal Ores, Methods of Extraction ...

Most metals can’t 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 are obtained in the form of compounds and they need to be filtered from their impurities to be further used for various applications.
