Abstract
A system for denitrating a starting nitric acid solution by irradiation of microwaves to obtain oxide product of the solution comprises a receiver for receiving the solution, a rectangular oven vessel provided with a bottom plate on which the receiver is put, and a conveying mechanism located below the bottom plate for continuously conveying the receiver on the bottom plate throughout the oven vessel. A microwave generator is operatively connected to the oven vessel for generating microwaves to irradiate the content of the receiver when it passes throughout the oven vessel. The receiver may be rotated and vertically moved when it is subjected to denitration and calcination in the oven vessel.
