ABSTRACT:
An improved solid-liquid separation step for use in connection with the Stretford process introduces a small amount of an additive which is then emulsified and mechanically treated in a colloid mill or processed through an air dissolver before introduction into a flotation cell. The process uses dissolved air and/or dispersed air to float the elemental sulfur while simultaneously regenerating the Stretford solution for recirculation.
