  • The Working Group on Mineral Exploration and Development (Other Than Coal & Lignite)
    REPORT OF THE WORKING GROUP ON MINERAL EXPLORATION AND DEVELOPMENT (other than Coal and Lignite) FOR THE ELEVENTH FIVE YEAR PLAN OVER VIEW VOL - I GOVERNMENT OF INDIA PLANNING COMMISSION January, 2007 1.0 REVIEW OF THE ACTIVITIES OF THE Xth PLAN 1.1 Geological studies carried out in past half-century have delineated vast area suitable for hosting mineral deposits. However, most of the exploration activity in the country even in the post-independence era remained confined to the stretches traditionally known to be locales of mining activities. Industrialization has led to manifold growth of mineral sector and fast depletion of known and near surface deposits would be the unavoidable result. During the Xth Plan, the need to adopt modern exploration techniques and beneficiation technologies was felt, mainly to locate the concealed mineral deposits and utilize the low-grade ores, which were hitherto being discarded as waste. 1.2 The Indian landmass measures 3.28 million sq.km., of which 2.42 million sq.km is constituted of hard rock. Out of the total hard rock area, approximately 7,00,000 sq km (5,71,000 sq.km. for Schedule Minerals) has been identified to contain geological associations and surface shows indicative of possible mineral occurrences. 1.3 During the Xth Plan (2002-2007) major thrust has been accorded to exploration for high value minerals like gold, diamond and platinum group of elements (PGE). Efforts for augmenting resource base for those mineral commodities having key role in sustaining industrial growth were also continued. Application of state-of-the-art technology for exploration and integrated multi-disciplinary approach were introduced during this period.

  • Microwave Energy Aided Mineral Comminution
    Proceedings of the International Seminar on Mineral Processing Technology - 2006, Chennai, India. pp.398 - 404. Microwave Energy Aided Mineral Comminution Ashish Kumar, Bala P. Kamath*, V.V. Ramarao* and D.B. Mohanty Central Research & Development Laboratory, Hindustan Zinc limited, Zinc Smelter, Debari — 313024, Udaipur (Rajasthan), India * Corresponding authors Email : [email protected] Abstract Mineral liberation during beneficiation is essentially through comminution. However, the fact that the major slice (up to 50 percent) in the pie for total energy requirements during beneficiation is occupied by comminution, dictates us to look into various possibilities to render comminution more energy-efficient. In the early 1900s, efforts for reduction in the crushing and grinding energies based on the concept, 'thermally assisted liberation' (T A L) were made but could not be commercially exploited. With the advent of microwave energy and applications in different commercial operations based on its property of heat generation in materials encouraged it in utilizing as an aid during comminution. Microwave energy heats individual phases in an ore matrix to different heat levels as per individual microwave absorption characteristics. Exposure to microwave energy over discrete time intervals prior to comminution results in development of micro fractures due to differential heating. Weakening of interspatial bonding in the ore matrix helps in lesser energy requirements. Numerous studies on microwave energy applications in the field of mineral processing and extractive metallurgy are undertaken in many parts of the world in recent years. With an ambition for implementing microwave technology at the production level in the beneficiation plant operations of Hindusthan Zinc Limited (HZL) as a platform change technology, Central Research and Development Laboratory has included in its road map a project to work on the concept.
