Uranium beneficiation in Sillamäe started in 1948. A total of 22.5 tons of elemental uranium was produced from about 271,575 tons of graptolite argillite from an underground mine near Sillamäe town [].Due to low uranium concentration and primitive technology, a large part of the uranium was left in solid waste.

The uranium concentration decreases from 2.8 PPM to 1.8 PPM, thorium decreases from 13 PPM to 9.3 PPM, and radon decreases from 11.5 PPM to 10.5 PPM as the iron assay decreased from 13.2% Fe 2 O 3 to 0.5% Fe 2 O 3. These results show that the radioactive minerals are associated in this rock with the iron-bearing minerals.

Uranium processing, preparation of the ore for use in various products.. Uranium (U), although very dense (19.1 grams per cubic centimetre), is a relatively weak, nonrefractory metal. Indeed, the metallic properties of uranium appear to be intermediate between those of silver and other true metals and those of the nonmetallic elements, so that it is not valued for structural …
