Obtaining High-Purity Tantalum Pentoxide in a Pulsed Column Operating in the Countercurrent Mode

摘要

The advantages of the purification of tantalum hydroxide in the continuous mode on a pulsed column have been studied. This method allows for the obtainment of a high and stable quality of tantalum hydroxide, a decrease in the losses of the final product yield, and a considerable increase in labor productivity.
