Uranium Mining in and for Europe

Uranium mill tailings still contain the largest share of the activity inventory of the original uranium ore, also in forms of decay products of the uranium like e.g. Radium, as well as heavy metals. They need to be stored in special pools for a long time.

Revalorization of Haveri Au Cu mine tailings SW Finland

The aim of this work was to make an estimate of the remaining metal resources of the Haveri tailings SW Finland that were deposited for 60 years ago. We used existing databases Cu, Zn, Ni, Co, As, Pb, Ag, Au, Fe, S of previous valorization performed in the 1980's with high sample density a total of 1201 tailings samples from 165 drill cores.

The concerns towards AMD rises when the waste rock and tailings are enriched in pyrite and/or pyrrhotite. The presence of trace of heavy metals bearing minerals increases the environmental hazard of such material. And the large volume of solid waste produced during operation leads to a high pollution risk. AMD is characterized by the release of acidic runoff water enriched in sulfate and

Isotope separation

18/2/2014· Isotope separation is the process of concentrating specific isotopes of a chemical element by removing other isotopes. The use of the nuclides produced is various. The largest variety is used in research e.g. in chemistry where atoms of marker nuclide are used to figure out reaction mechanisms. By tonnage, separating natural uranium into enriched uranium and depleted uranium is the largest
