Question
What is a mineral? How does it differ from an ore ?###Differentiate between mineral and ore.

Answer

Minerals are those substances which are extracted from earth crust by mining. For example, Petroleum metallic compound etc.
Ores are those mineral from which metals can be extracted profitably i.e., all ores are minerals but all minerals are not ores. For example, haematite $ (Fe_{2}O_{3}) $.
