Presence of trace amounts of gypsum either with alumina or kaolinite is found to markedly increase the sulfonate uptake by these minerals. It is shown that in kaolinitegypsum and aluminagypsum mixtures, the total abstraction at high sulfonate levels is due to adsorption on alumina and kaolinite and precipitation caused by gypsum.
