Abstract

See full text

Processes for recovering an organic solvent extractant phase from a solid-stabilized emulsion formed in a hydrometallurgical solvent extraction circuit are disclosed. One such process includes mixing a de-emulsifier comprising an effective amount of a polymeric aggregating agent with the solid- stabilized emulsion, thereby separating the emulsion into its aqueous, organic, and solid phase components; and removing the organic solvent extractant phase from the other components, thereby recovering the organic solvent extractant phase from the solid-stabilized emulsion.
