Minerals are naturally occurring chemical substances containing metals. They are found in the Earth’s crust and are obtained by mining. Ores are rocks and minerals viable to be used as a source of metal.
For example, there are many minerals containing zinc, but zinc cannot be extracted profitably (conveniently and economically) from all these minerals. Zinc can be obtained from zinc blende (ZnS), calamine (), Zincite (ZnO) etc.
