Uranium Mineral Systems: Mineralisation, Resources Genetic Models and New Understandings of Deposits

Susan M Hall (USA)

The dramatic increase in cost of Uranium since 2005 has resulted in discovery of new occurrences and interest in uranium mineral system. Mineralogy and geochemical characteristics of these new occurrences have been studied extensively. Now the time has come when information generated by the understanding of such development should be discussed across the globe. Recently IAEA has published review on existing uranium deposits classification and proposed a classification scheme based on genetic understanding. This symposium therefore invites papers on

1: Uranium deposit types, genetic models and its understanding.

2: Mineralisation, geochemistry, mineralogy and classification of uranium deposits

Advances in Uranium Exploration and Exploitation

Michel Cuney


Economic uranium deposits resulted from original inhomogeneity’s of uranium distribution in the Earth’s crust that commonly persisted through long periods of time, and through a combination of orogenic, metamorphic, and sedimentary processes produced rocks with enriched uranium contents. The initial enriched uranium domain was successively remobilized and concentrated into new enrichments of one or more magnitudes above normal background forming uranium ore deposits. This symposium aims to discuss nature, origin, evolution, and distribution of U provinces. The modelling and exploitation related development will also be discussed.

Unconventional Uranium resources: A Global Perspective

Patrice Bruneton


This symposium intends to discuss unconventional uranium resources as recoverable resources associated with phosphate rocks, non-ferrous ores, carbonatite, black shale and lignite. They correspond to low to very low grade, generally very large geological resources where uranium can only be extracted as a co- or by-product. Mostly it is not possible with existing technologies to recover them rather they are the future resources due to development of technological advancement. Economics play a vital role in this process. The unconventional resources are associated with intrusive plutonic, polymetallic iron oxide– copper–gold breccia complexes (IOCG-U), volcanic-related, Au-rich palaeo-quartz-pebble conglomerate, placers, lignite–coal, phosphorite and black shale [6]. The largest unconventional resources are in seawater, with resources estimated at 4 billion t at an average ‘grade’ of 3.3 ppb (3.3 mg/m3).

Thorium, resources, technology, energy generation

The increased demand of carbon-free energy, requires the sustainable use of fuel resources such as uranium and thorium. Uranium though is the main-stay of the present generation of Nuclear Power Plants, with the anticipated steep growth in nuclear energy it will be necessary to introduce thorium too as a fuel. Thorium fuel cycle offers several potential advantages over a uranium fuel cycle, including greater abundance, superior physical and nuclear properties of fuel, enhanced proliferation resistance, and reduced plutonium and actinide production. Technically thorium has been well established and it behaves remarkably well in Light Water Reactors, High Temperature Reactors and Liquid Fluoride Thorium Reactors. Recognizing the potential contribution of thorium fuel cycle in nuclear energy, renewed R&D efforts is seen in much country. Geologically thorium deposits are found in alkaline complexes, pegmatites, carbonatites and heavy mineral sands with wide geographic distribution. Major resources of thorium are seen in Australia, Brazil, Canada, India, Norway, South Africa and USA. Thorium exploration is presently continuing in some countries such as India and USA. The present production of thorium is mainly as a by-product of processing of heavy mineral sand deposits for titanium, zirconium and tin.

The symposium is targeted to discuss latest information on the latest developments in geology, mineralogy, exploration, resources, production, ore processing, environmental studies, safety and social licensing aspects.

Nuclear Energy, Sustainable Development, Low Carbon Energy and Mine Tailing.

This symposium is planned to discuss sustainable development in the coming decade will be crucial for all countries, setting the stage for the rest of the 21st century. The 2030 Agenda for Sustainable Development set ambitious goals to ensure prosperity and security for the entire planet. All the 17 goals outlined in 2030 Agenda will require massive energy and material flows. Moreover, the goals encompass low-carbon foot-print and minimum impact to the environment during the production of energy and materials.

Nuclear energy will have a significant role in the low-carbon energy mix that will power the world on a sustainable path. Most of the energy scenarios for maintaining the 2°C increase above the pre-industrial levels in global temperature require a high share of nuclear energy. Large-scale utilization of nuclear power is foreseen in many countries, especially in the most populous India and China. Under the IAEA high case scenario nuclear power would see a 3-fold increase by 2050.

Uranium has to be seen as a low carbon fuel that can help realize many of the Sustainable Development Goals and climate commitments. Uranium resources to power the fleet of reactors are not only required in a timely manner but also need to be produced sustainably. The comprehensive recovery of uranium from unconventional resources including from wastes and tailings will be significant in future. In addition to new technologies for obtaining more uranium, the nuclear energy industry will have to examine practices in resource management including safe handling of mine tailings and long-term storage of spent fuel to ensure sustainability.

Geological aspects, exploration and economics of coal deposits

Coal is the second most important energy source, covering 30% of global primary energy consumption and is the leading energy source in power generation accounting 40% of globally generated power. Many of the developing countries, including India, is well endowed with coal resources and these countries are increasingly satisfying their growing energy demands with cheap coal in order to sustain their economic growth. Hence, despite its insidious influence on the climate and health, coal is unlikely to be replaced in near future as the major player in energy scenario in most of the countries.

Coal deposits of the world formed from plants that grew in and adjacent to swamps, mostly, in warm, humid regions. Under certain conditions this organic material continued to accumulate and was later converted into coal. There are distinct time spans during which most of the world coal deposits were formed which represent periods during which several favourable biological and physical processes occurred simultaneously. Study on paleogeography, tectonic framework, paleobotany, palaeoclimate and sedimentary history helps to understand the depositional environment that favoured coal formation.

This symposium will cater to all researchers related to the geological aspects, exploration and economics of coal deposits.

Coal, coal characterization, coal beneficiation, coal utilisation

Coal is likely to continue to be the major source of energy for many years to come but the manner in which coal is used must, and will, change. Advances in analytical techniques, modeling software with high power of computation system have resulted in improved partial representation of coal structure. but complete grasp on chemical constituents, their structure and their binding mechanism for the solid fuel is remain elusive.

Coal, with high carbon content than other fossil fuels, produces maximum CO2 when combusted. In addition, coal also contains a host of elements including Sulphur, nitrogen, mercury and heavy metals which pollute the environment when coal is mined or burnt.

Coal research has evolved to reduce all the disadvantages it has in conventional method. Today coal is seen in various ways of utilization with the help of many new and evolving techniques of characterization in molecular level. We have technologies in hand that will allow coal to be used in a more environmentally friendly manner. It seems that opportunities still exist for developing new processes and technologies, which need to be more economic, effective and efficient that may be unconventional in nature. This symposium therefore invites papers on Coal petrography, coal chemistry and beneficiation.
