    Why is conservation of mineral resources essential? Explain any three methods to conserve them.

    Answer:

    Minerals are important for every country for it?s development and they need to be conserved because industry and agriculture depends upon minerals and the substances manufactured from them. Mineral resources are fund resources and require millions of years to be renewed. The natural rate of replenishment is very small in comparison to the present rates of consumption. Mineral deposits in our country will get exhausted in the future. In search of good quality, they come from great depths so, the cost of mineral extraction is increasing. Minerals can be conserved by the following measures:
    (i) Use of improved technologies need to be constantly evolved to allow use of low-grade minerals at low costs.
    (ii) Recycling of metals is a good way in which the mineral resources can be conserved.
    (iii) Usage of mineral resources should be planned in a sustainable manner.
