Question

What is an example of a common oxide mineral?

Answer 1

1. Minerals are the natural substance from which metals or their compounds are found on the earth.
2. Some minerals may have a large percentage of metals in them or some have less percentage depending on the objectionable impurities present in them that hamper the extraction of metals.
3. Similarly, those minerals from which metals can be extracted very easily or conveniently and profitably are known as ores.
