Uranium and Thorium Resources in India: UNFC System Uranium and thorium resources in India: UNFC system P.S.Parihar Atomic Minerals Directorate for Exploration and Research Department of Atomic Energy Government of India 1 21/08/2013 Government of India’s Policy on Atomic Minerals The federal status of the DAE and the powers invested in it under the Indian Atomic Energy Act (1948 and 1962) as amended from time to time, bestow upon it several rights to facilitate atomic mineral exploration. The more significant ones are- . Exclusive rights to conduct exploration for uranium, thorium and other prescribed minerals such as beryllium, lithium, niobium, tantalum and rare-earth elements all over the country . Exclusive rights to buy prescribed minerals from private mine owners produced incidental to mining of other economic minerals. 30/10/2013 - . Rights to access to surface and sub-surface data on areas under exploration or mining/recovery for oil, coal, minerals and ground water by Government or Public Sector Organisations. The facility includes carrying out of gamma-ray logging of boreholes and checking of mine workings and collection of samples etc. 2 UNFC workshop, New Delhi workshop, UNFC Government of India’s Policy on Atomic Minerals Uranium exploration, production and utilisation are under the control of Central Government.

Two agencies, viz., Atomic Minerals Directorate for Exploration and Research (AMD) and Uranium Corporation of India Limited (UCIL) under the Department of Atomic Energy are engaged in the exploration and mining of uranium, respectively for its exclusive use as fuel in the nuclear power stations owned by Government of India. As per UNFC, reporting of resources are to be done by numerical coding on three axes (E,F&G). The geological details (G) and feasibility status (F) of almost 30/10/2013 - all the Indian uranium and thorium deposits have been widely reported, but the details related to the economics (E) is not reported. As a result, the classification with reference to E axis may be 5 UNFC workshop, New Delhi workshop, UNFC difficult for Indian deposits.

All the evaluated thorium resources in India is confined to the mineral monazite occurring in the beach sand heavy mineral suite of East and West coasts. Indian resources fall under the category “VI.

Though trade restrictions continue to impede completely free access to the worldwide uranium market, the uranium resources and production capabilities of the developing countries are becoming increasingly important in assuring the adequacy of uranium supplies to meet projected worldwide demand. Therefore, papers presented at this meeting provide an important overview of uranium production operations in developing countries as well as offering insight into future production plans and potential. Along with their increasing contribution to worldwide uranium supply, the environmental impact of uranium production in developing countries has come under increasing scrutiny

Charge consisting of oxides of titanium, iron, calcium and metallic aluminum is being heated to V) the temperature of 800-1000OC and set on fire with ignition mixture. Carbon can be used instead of aluminum. As the second option the following process is offered: titanium oxide is being mixed with any source of carbon (soot, coal etc.), heated and soaked at temperatures up to 1000 0C-25000 C. Then in the process of melting oxides of titanium, iron and/or metallic iron are being added. 00 00 (N, THE TECHNOLOGY OF PRODUCING FERROTITANIUM 00 0 Ferrotitanium is a metallic alloy of titanium and iron and it is widely used as an active alloying Cq addition in the production of stainless and interstitial free steels. Traditionally ferrotitanium is produced by using metallic scrap. However production of ferrotitanium by reduction of titanium V oxides did not find wide application due to the absence of robust technology that would allow to produce ferrotitanium with 70% titanium contents.

  • Heavy Mineral Sands in Brazil: Deposits, Characteristics, and Extraction Potential of Selected Areas
    minerals Case Report Heavy Mineral Sands in Brazil: Deposits, Characteristics, and Extraction Potential of Selected Areas Caroline C. Gonçalves and Paulo F. A. Braga * Centre for Mineral Technology (CETEM), Av. Pedro Calmon 900, Cidade Universitária, Rio de Janeiro 21941-908, Brazil; [email protected] * Correspondence: [email protected]; Tel.: +55-21-3865-7222 Received: 15 January 2019; Accepted: 6 March 2019; Published: 13 March 2019 Abstract: In Brazil, heavy mineral sand deposits are still barely exploited, despite some references to Brazilian reserves and ilmenite concentrate production. The goal of this project is to characterize and investigate the potential recovery of heavy minerals from selected Brazilian placer occurrences. Two areas of the coastal region were chosen, in Piaui state and in Bahia Provinces. In all samples, the heavy minerals of interest (ilmenite, monazite, rutile, and zircon) were identified by scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques and also quantified by X-ray fluorescence spectrometry (XRF) and Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). The total heavy minerals (THM) in the Piaui samples were 6.45% and 10.14% THM, while the figure for the Bahia sample was 3.4% THM. The recovery test of the Bahia sample, using only physical separation equipment such as a shaking table and magnetic separator, showed valuable metallurgical recoveries at around or greater than 70% for each stage, and the final concentrate of pure ilmenite was composed of up to 60.0% titanium dioxide after the differential magnetic separation. Another aim is to compile accessible information about Brazilian heavy mineral main deposits complemented with a short economic overview.
