Solvometallurgy: An Emerging Branch of Extractive Metallurgy
The uranium ore is crushed to a particle size of less than 10 mesh, mixed with concentrated H 2 SO 4 and a small amount of water, and cured for about 1 h to dissolve the uranium in the form of uranyl sulfate and to neutralize any of the lime that the ore might contain. The amount of acid used in this step is equivalent to that required for a ...

Uranium ore beneficiation
Ore beneficiation is the extraction of higher grade fraction from the mined uranium ore, by physical means such as kinetic processing and/or sorting. It is used for low-grade uranium ore to considerably reduce the amount of material that has to be processed in a uranium mill, while losing only a minor fraction of the contained uranium.

The basic concept of the invention is a froth flotation process to beneficiate uranium economically from both low grade tailings dump ores or high grade ores; by upgrading into a concentrate. The total flotation time required is approximately 74 minutes (depending on feed grade, flotation kinetics and cut-off grade required) with multiple ...
