Het Uraan in een gronmosnsters wordt in oplossing gebracht door ontsluiting met een mengsel van salpeterzuur-Aluminiumni-traat. Het Uraan Wordt gestcheiden van de andere elementen op chromatografiepapier, waarna de kleuring volgt met een organisch reagents.
Orientation studies indicate that stream-sediment geochemistry is a potentially useful exploration tec~ique in the Kepala Burung region of Irian Jaya, Indonesia. Previously located uranium anomalies and small zones of known base-metal sulphide. mineralisation, are reflected in anomalous concen• trations of these elements in•the stream sedim…
Radioactive detrital heavy minerals are found in the beaches and coastal thelves of te Capoas-Erawan area, San Vicente, Palawan. Allanite, sphene, zircon and monuzite ae the min suspected to contain uranium, thorium and rare earths (e-g Ce, Y) Other heavy minerals, tope rutile, anatase, castiterite, muscovite, hornblende, orthoclase and plagioclase …
WORLD URANIUM RESOURCES, PRODUCTION AND DEMAND.
Reasonably assured resources of uranium in WOCA (World Outside the Centrally
Plannned Economies Area) countries recoverable at less than US $80/kg U increased by about 9%
between 1983 and 1985 and currently stand at 1.5 million tonnes. Uranium also exists in
si…
Experimental simulation of Colorado Plateau type uranium deposits is di- vided into seven parts. The first three summarize the essential features of geological occurrence for the ores. Details are omitted since they are avail- able in other reports to which reference is made. The last four parts out- line the results …
methods can thus often be based on the measurement of trace quantities of the metal itself in waters, soils, sedi• ments or rocks. In Canada, for example, centre-lake sedi• ments and lake waters have been widely used during the National Geochemical Reconnaissance survey (Cameron A new t…
