ABSTRACT:
A process for recovering oil containing dissolved alkaline earth metal sulfonate from siliceous filter cakes containing such oils by mixing the filter cake with sufficient 0.5 to 16N sulfuric acid or phosphoric acid to bring the pH of the mixture to a level in the range about 2 to 7, settling the acid-filter cake mixture to separate an upper oil-sulfonate phase and recovering the upper phase.
