Study on the Oxidative Leaching of Uranium from the

Abstract. Na 2 CO 3 /NaHCO 3 mixtures with different oxidants were used to leach uranium in the lignite which was obtained from Lincang, Yunnan province. The experimental results showed that the optimal solid/liquid ratio and / ratio for uranium leaching were 1 : 20 (g/mL) and 2 : 1, respectively. With the increase of carbon concentration from mol/L to mol/L, the leaching efficiency of

Extraction and Recovery of Radium, Uranium and Vanadium

After the product had been put through a ball mill and leached with water, the filtrate contained most of the vanadium that had been in the original sodium uranate, and this was recovered in the usual way. The leaching also washed out the soda which was

Photo of the Week: Ball and Tube Knocking System

This week's photo highlights a ball and tube knocking system. Knocking systems are often implemented to combat build-up inside of a rotary dryer. The systems are usually externally fitted on the inlet end of the dryer, where the incoming material is most wet and sticky. As the name suggests, knocking systems "knock" off any material build

Integral transform analysis of radionuclide transport in

Conventional mines generally contain milling facilities where the ore is crushed, placed in leaching platforms, and then leached with sulfuric acid to dissolve the uranium oxides. The uranium content of ore is often only between % and %, which means that large amounts of ore have to be mined to produce a justifiable amount of uranium.

Heavy metals - Wikipedia

Heavy metals are generally defined as metals with relatively high densities, atomic weights, or atomic criteria used, and whether metalloids are included, vary depending on the author and context. In metallurgy, for example, a heavy metal may be defined on the basis of density, whereas in physics the distinguishing criterion might be atomic number, while a chemist would likely be
