Track 8. Uranium from unconventional resources
ORAL
INTRODUCTION
Unconventional resources are defined in the 2016 version of the Red Book as “Resources from which uranium is only recoverable as a minor by-product, such as uranium associated with phosphate rocks, non-ferrous ores, carbonatite, black shale and lignite” [1].
Unconventional resources of uranium are recorded in UDEPO, the IAEA Uranium DEPOsit Database [2, 3]. They correspond...

Abstract
From the early days of the nuclear power industry, Australia witnessed a “Yellowcake Rush”, with prospectors scouring our countryside for uranium resources. Large resources of the metal were identified and a relatively buoyant market led to investment and a uranium export industry, despite a challenging political environment. A prevailing weak market for Uranium since the March...

While the initial search for uranium dates back as early as 1954, it was only in 1977 that the systematic exploration approach for uranium was started under the International Atomic Energy Agency (IAEA) Technical Cooperation (TC) project PHI/3/04 “Uranium Geochemical Prospection” [1]. This was tied up with the decision of the Philippine Government at that time to establish the Philippine...

INTRODUCTION
The Amazonian Craton (South America) hosts several favourable areas for uranium exploration that are still barely acknowledged. The most significant of the recognized resources are in the Carajás Province, the oldest known Archean crustal fragment in the craton. Identified uranium resources are unconventional, hosted by the world-class IOCG deposits from the Carajás Copper-Gold...

The phosphate fertilizer industry is one of the key player in sustaining and the continuing development of the vastly agricultural Philippine economy. Since 2002, phosphate-based fertilizers have become one of the most important and consumed fertilizer next to nitrogen-based fertilizers [1]. About 60% of produced and imported fertilizers are consumed by major and staple food crops such as...

Phosphate rocks are widely exploited for the manufacturing of phosphoric acid and fertilizers but they contain uranium (30-300 ppm). Therefore, recovering this uranium would enable the decontamination of phosphoric acid while valorizing uranium for the nuclear industry. New extractant molecules were investigated in the past few years to develop a new solvent extraction process. An...

A leaching reagent (LR) has been successfully used (for environmental importance) to leach - (remove) - uranium from input phosphate ores prior to processing for production of phosphatic fertilizers (and phosphoric acid), without dissolution of any amount from the phosphate mineral. In (traditional) phosphate industry, rock phosphate is digested with sulfuric acid for production of...

The ocean contains a large quantity of dissolved uranium (over 4 billion ton U) and has long been regarded as an inexhaustible uranium resource. However, due to its low concentration in seawater (3.3 parts per billion), developing a cost-effective recovery method remains a challenge. In October 2010, the U.S. Department of Energy, Office of Nuclear Energy (DOE-NE) held a workshop on...
