Question

Justify ----- 'all ores are minerals but all minerals are not ores'.

plzz give the appropriate answer..​

Answer 1

Explanation:

To be called an ore a mineral must be a viable raw material for the production of a particular metal or other product. For example galena is an ore of the metal lead and magnetite is a major ore of iron. On the other hand calcite is a mineral that that is not used for the production of metal and so is not regarded as an ore.

Minerals are the naturally occurring inorganic substances which contain one or more metals,in their native state or as their compounds, along with impurities. On the other hand, the minerals from which a metal can be conveniently and economically extracted are called ores of that metal. Obviously, all ores are minerals. But,we cannot extract metals from any mineral by convenient and cheap methods. Hence all minerals cannot be ores.

For example,both bauxite and china-clay are the minerals of aluminium. But only bauxite is considered as the ore of aluminium,not china- clay.
