Abstract: In this research paper we are proposing a method for extracting Thorium from rare earth minerals in the form of Thoria. It is found that the occurrence of Thorium in the earth is abundant than Uranium, then also the rate of extraction of Thorium, is minimal now a days. There are chemical reactions that can yield almost hundred percentage of Thorium as an extracted process but there is no formal industrial level of extraction process happening nowa days. In this paper we are proposing a process which can achieve almost 99.99% of thorium extraction from the earth minerals in industrial level.
