CARBONATITE DEPOSITS (MODEL 10; Singer, 1986a)
Nature of ore Ore minerals may be disseminated throughout a large volume of carbonatite, or may be banded and concentrated in certain intrusive, alteration, or breccia zones, or in carbonatite dikes and sills. Deposit trace element geochemistry Most deposits are enriched in Th, U, Ti, Zn, Nb, Y, Mo, Cu, V, P, Mn, S, La, Ce, Sm, Eu, Pb, Zr, and Ba.

Uraninite - Wikipedia
Uraninite, formerly pitchblende, is a radioactive, uranium-rich mineral and ore with a chemical composition that is largely UO 2 but because of oxidation typically contains variable proportions of U 3 O 8. Radioactive decay of the uranium causes the mineral to contain oxides of lead and trace amounts of helium.It may also contain thorium and rare-earth elements.

The Koenigsberger ratio Q peaks in the uranium ore with a value of ∼1.00. Using the systematic rock magnetic results to constrain the interpretation, the contribution of the intersection zone of diabase dyke and silicified fault to magnetic anomalies was further modeled, and the effects of the ore body are significant for magnetic exploration.

illustrates the southern extent of the Simandou Formation and therefore in the targeting iron ore has been considered as a possible commodity for further exploration. However, the radiometric images indicate a relatively higher concentration of uranium in the southern concession and therefore this is the primary commodity for exploration.

Uranium Enrichment | NRC.gov
Enriching Uranium. The nuclear fuel used in a nuclear reactor needs to have a higher concentration of the U 235 isotope than that which exists in natural uranium ore. U 235 when concentrated (or "enriched") is fissionable in light-water reactors (the most common reactor design in …

Magnetite - Wikipedia
Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of ...

Magnetic and Gravity Methods in Mineral Exploration: the ...
Magnetic methods are more popular in mineral exploration than gravity, not least because magnetic data can be quickly recorded from the air and in conjunction with other geophysical surveys. Land gravity surveys, by contrast, may require greater field efforts (Figs. 1, 5 and 6), more time, and more commitment of scarce capital.

Cameco U101 - Finding Uranium
Concentrations of uranium that are economically viable to mine are considered ore and range from about 1,000 up to 200,000 parts per million uranium. After targets have been identified the next stage of exploration is core sample drilling. Core samples are taken from the target location until a deposit is located or the anomaly has been explained.
