The agricultural and industrial sector is strongly dependent upon the mineral deposits which are limited in nature- only one percent of the earth crust. The geological process of formation of a mineral is very slow as compared to the rate of consumption. The minerals are finite and Non Renewable. The use of improved technology needs to be developed to allow the use of low-grade ores at a low cost. Other steps to conserve mineral resources are recycling of metals and using scrapped metals and other substitutes.
