Interpretation: The terms mineral, ores and metallurgy have to be defined.
Concept Introduction:
Occurrence of Metals:
Metals do not occur in their pure form naturally. Metals can only occur in the form of minerals. Ore is extracted from mineral and it is subjected to metallurgy in order to separate the desired metal from the ore and the separated metals are purified using various techniques. By this process, metals are obtained in their purest form.
Explanation of Solution
Mineral: A mineral is naturally occurring substance with a wide range of chemical compositions in it.
Ore: An ore is substance in which the mineral deposit is enough concentrated in order to economically recover the desired metal from it.
So, all minerals can be ores and no ores can be minerals.
Metallurgy: It is the scientific technology of separation of the desired metal from the ore or compounding alloys.
