Latest Patents

Cohen holds a patent for the "Recovery of alkali values from trona ore." This patent describes a cyclic method for recovering alkali values from mechanically mined trona ore or trona deposits. The process utilizes a solution mining technique with a solvent that comprises an aqueous solution of sodium sulfide. The ore is solubilized as sodium carbonate, which is then precipitated as sodium sesquicarbonate and/or sodium bicarbonate by treating the solution with hydrogen sulfide. The precipitated salt is separated from the mother liquor, and sodium sulfide and hydrogen sulfide are converted into sodium hydrosulfide, which is contained in the mother liquor. Heat treatment of the mother liquor regenerates sodium sulfide, allowing for recycling within the process.
