Minerals and Energy Resources
Why is conservation of mineral resources essential? Explain any three methods of conserving mineral resources.
The geological processes of mineral formation are so slow that rates of replenishment are infinitely small in comparison to the present rates of consumption.
Mineral resources are, therefore, finite and non-renewable.
The methods for conservation:
(i) Improved technologies need to be constantly evolved to allow use of low grade ores at low coasts.
(ii) Recycling of metals, using scrap metals and other substitutes.
(iii) Usage of mineral resources in planned and sustainable manner.
