In this survey, some methods of extraction of thorium such as selective extraction of thorium using phosphorodiamidate, selective cloud point extraction of thorium, extraction of thorium from sulfuric acid baking and leaching of monazite, extraction of thorium from chloride solution using Schiff base were discussed. The decomposition of monazite was manifested by sulfuric acid baking and leaching at an elated temperature. The recovery of thorium (Th) from various sources of rare earth and some selective extraction of thorium by using phosphorodiamidate as an extractant was also reported. Using a special synthesized surface-active ionic liquid extractant (SAIL), the cloud point extraction of thorium was analyzed. A synthesized Schiff base was applied for the extraction of thorium in the strategic solvent extraction method. Thorium, using α-amino phosphate extractant from bastnaesite, recovered by using Cyanex 572 and N1923, recovery of Th from industrial residues and recovery of Th from radioactive waste by using IREPO and monazite leached solution were discussed. In this study, the recovery of thorium from the industrial residue as well as from radioactive residue was also discussed.
