Question

Any rock containing metallic mineral is called an ore. True or false?


Solution

False. Any rock containing metallic mineral is not an ore as it depends on the quantity of metal in the rock. If the quantity of metal in the rock is less, it cannot be extracted profitably. Thus, rocks containing metallic minerals in adequate quantity, from which metals can be extracted profitably, are called ores.
