Mine Waste as Resource: Indian Mining Scenario of Coal and Non Coal Mining Sector
The International Journal of Recent Technology and Engineering (IJRTE), 2021 Mother Nature has bestowed India with huge resources of coal, iron ore, bauxite, manganese and limestone. India has one of the lowest per capita availability of land due to population of more than 1.3 billion. The transformation from under developed to developed economy warrants enormous increase in mineral production.
