FIELD: metallurgy.
SUBSTANCE: invention relates to hydrometallurgy, to extraction of organic solvent extractant phase from an emulsion, stabilised with solid particles, formed in a hydrometallurgical solvent extraction circuit. Disclosed method includes mixing a de-emulsifier comprising an effective amount of a polymeric aggregating agent with solid-stabilized emulsion. Emulsion is separated into its aqueous, organic, and solid phase components, and organic solvent extractant phase is removed from emulsion.
EFFECT: higher extraction of solvent, shorter emulsion processing time, reduced cost of extraction of valuable components.
