Uranium: How is it Mined?

Autunite is a radioactive orthorhombic mineral which results from the hydrothermal alteration of uranium minerals. Used as a uranium ore, it was first discovered in France in 1852. Autunite is one of the more attractive and popular radioactive minerals. To state the obvious, the uranium in its chemical formula provides this radioactivity.

This mine is the largest reserve of uranium in the country and its economic viability depends on the associated phosphate exploration. This means that the uranium extraction is subject to the production of phosphoric acid-raw material used in the production of fertilizers (agroindustry).

Uranium Mining Overview

Source: USGS 2020 1. Phosphate rock (phosphorite) is a marine sedimentary rock which contains 18-40% P 2 O 5, as well as some uranium and all its decay products, often 70 to 200 ppmU, and sometimes up to 800 ppm.The main mineral in the phosphate rock is apatite, and most commonly, fluorapatite – Ca 5 (PO 4) 3 F or Ca 10 (PO 4) 6 (F,OH) 2.This is insoluble, …

Most of the uranium ore deposits at present supporting these mines have average grades in excess of 0.10% of uranium – that is, greater than 1000 parts per million. In the first phase of uranium mining to the 1960s, this would have been seen as a respectable grade, but today some Canadian mines have huge amounts of ore up to 20% U average grade.

Uranium from Phosphates | Phosphorite Uranium

• Uranium can be recovered as a by-product from phosphate fertilizer production and from the mining of other minerals including copper and gold when the ores contain economically exploitable quantities of uranium. In such situations, the treatment process to recover uranium may be more complex.
