Explanation: Ores and Minerals
What are Minerals?
Minerals are naturally occurring inorganic substances with definite chemical compositions and physical properties. They are formed by various geological processes and are found in various forms such as crystals, rocks, and ores. Examples include quartz, feldspar, mica, and calcite.
What are Ores?
Ores are minerals from which metals or other valuable minerals can be extracted profitably. They are deposits of minerals that are economically feasible to mine. Examples include iron ore, copper ore, and gold ore.
Why all the ores are minerals but all the minerals are not ores?
The reason why all ores are minerals but not all minerals are ores is that ores are minerals that have economic value and can be extracted profitably. On the other hand, minerals that do not have economic value or are too expensive to extract are not considered ores.
For example, quartz is a mineral that is widely distributed in the earth's crust and has many industrial uses. However, it is not an ore because it does not contain any valuable metals or minerals that can be extracted profitably.
Similarly, feldspar is a common mineral that is used in the production of ceramics, glass, and enamel. However, it is not an ore because it does not contain any valuable metals or minerals that can be extracted profitably.
Therefore, all ores are minerals, but not all minerals are ores.
