Minerals Sector Presentation - 12th Plan (2012 - 2017)
Minerals in India- Key Strategies in the 12th Five Year Plan
MINERAL WEALTH AND MINING– Mineral assets play a direct role in the growth and prosperity and hence substantial investments is essential for exploration of these assets through different agencies having the requisite skills– India having 2.4% of the global area, sustains 17.5% (Census-2011) of the world population.– Our per capita consumption of minerals and its products is one of the lowest in the world.
• India has vast mineral potential but insufficient exploration technology.• The demand for various metals and minerals will grow 4-5 times over the next 15 years (9- 11% growth per annum).• The aspiration of the mining sector in the GDP is to increase from the current contribution of 2.3% to around 7-8% over the next 20 years.• The mining sector needs to play a major role if India has to realize the potential growth of 9% per annum in the coming years.
Key Objectives Under the TwelfthPlan• The mining sector is strategically very important for India. The key goals that need to be met for this space are:• Raw material security: for all the user industries• Enhanced co-production of by-product metals for technology metals and energy critical metals• Ensuring sustainability of the environment
Key RecommendationsA. Strengthening of Institutions• Equip and position public agencies like the Mineral Exploration Corporation Limited, Directorates of States and other organisations to conduct detailed exploration at the State’s expense to enable the State Government to adopt a bidding route for exploration to a larger extent.• Position GSI to emphasise on geospatial and multi- disciplinary work for the benefit of science, society and the nation.• An overarching mechanism to provide policy direction for geosciences is a must.
B. Encouraging R&D and Technology Development• Engage IBM to drive process of giving special focus in select areas of mining.• Strengthen the Mineral Process Laboratories of IBM and other research organisations must before the development of processes for beneficiation, elemental analysis of ores.• Inspire concessionaires to undertake deposit-specific process R&D.
C. Institutional Mechanism• Develop an institutional mechanism for the direct lab scale research to commercialisation for the production of materials of high purity,• Reorient focus of organisations like Non- Ferrous Technology Development Centre, Jawaharlal Nehru Aluminium Research• Development and Design Centre on process R&D for Technology and Energy Critical Metals.
• Creation of Infrastructure• Skill Development• Ensuring Full and Productive Coverage of Survey and Exploration• A Database of Mineral Resources Needs to be Developed• Ensuring Availability of Financial Resources• Policy Changes in Line with the Overall Strategy
Ensuring Environmental Sustainability of Mining• Promote a scientific and efficient process of small scale mining of small deposits• Regulations related to safeguarding the ecology must be ensured and their compliance strengthened.• A cluster approach must be adopted with a single lease model for multiple small deposits within a defined area• Undertake all mining undertaken within the parameters of a comprehensive Sustainable Development Framework• Under such a framework, no mining lease should be granted without a proper mining plan including an approved environment• management plan.• For this purpose, the IBM must acquire the expertise to approve Environment Management Plans and conduct• Environmental Impact Assessments. Thus, the IBM should be able to position itself as the internal environmental regulator as well as the official mining regulator for the sector.
