Abstract Solvent extraction plays a vital role in the production and processing of uranium and thorium for use as fuels in the front-end of the nuclear fuel cycle. The development of solvent extraction technology in the nuclear field in the last five decades has contributed to advances in the non-nuclear hydrometallurgy. In turn the large scale applications in the field of base metals such as

3.1.2 Toxic Elements and Other Chemicals in Tailings A number of toxic materials from ore or from chemicals used in processing have been found in both liquid and solid uranium mill wastes (Se75, FB76-78). The contaminants present depend on the ore source and the type of processing.

So potentially the uranium ore at the Rossing mine could produce an EROEI of 50,000. This is at a uranium concentration of 300 PPM. Now the thorium at Lemhi Pass is of a purity of between 25% to 63% of the ore. In other words a concentration many orders of magnitude greater than the uranium concentration of Rossing ore.

Recipes in Mining are listed under Smelting, a subskill which works exactly like any other crafting-profession. Although working like a separate profession, Smelting is part of Mining, and is automatically learned upon obtaining Mining. It's the ability which allows a player to process and refine raw ores into useful bars. Smelting is also often used to combine smelted metals into alloys.

U-233 does not occur naturally; it is formed when thorium absorbs a neutron undergoes a double beta decay to form U-233. U-233 is a superior nuclear fuel, producing enough neutrons through its fission

In the processing of monazite ore to separate uranium, thorium and rare earth elements composed in the ore, uranium is first extracted and precipitated in the form of sodium diuranate (Na 2 U 2 O 7) or yellow cake.This yellow cake requires further purification to remove thorium and traces of rare earth impurities from the cake.
