Latest Patents
One of Rickelton's latest patents is focused on the regeneration of dithiophosphorus acid metal extractants. This invention provides a method for regenerating dithiophosphorus extractants, such as dithiophosphoric acids, from their sulfur-sulfur bonded oxidation products contained in an organic solution. The process generates active hydrogen, which is crucial for regenerating spent dithiophosphorus extractants. This active hydrogen can be produced by introducing a reactive metal into a liquid mixture or by using hydrogen gas in the presence of a catalyst. The generated active hydrogen effectively breaks the sulfur-sulfur bonds of the dithiophosphorus molecules, leading to the formation of the corresponding dithiophosphorus acids.
Another significant patent involves the recovery of indium by solvent extraction using trialkylphosphine oxides. This invention outlines a process for recovering indium from aqueous acid solutions, utilizing a combination of dialkyl phosphoric acid and trialkyl phosphine oxides to extract indium from acidic sulphate leach liquors.
