Sodium dithiophosphate is the salt Na3PS2O2. This salt is used as a flotation agent in molybdenite mineral concentration from ores where it is usually known as Nokes reagent. The salt is generated by the reaction of phosphorus pentasulfide with sodium hydroxide often using impure reagents to obtain a mixture of the desired salt and related thiophosphates and oxidized species. Molybdenite particles which are normally hydrophobic become hydrophilic in the presence of this salt.
