FIELD: metallurgy.
SUBSTANCE: method involves contact of an extractant and a solution, mixing of the mixture, sedimentation and separation of organic and water phases. Extraction is performed with vegetable oils. The process is performed at the ratio of water (WB) to organic (O) phase of W:O ≤ 7, pH 7-10 and adjustment of pH value during not more than 60 minutes.
EFFECT: high degree if efficiency of zinc extraction from water solutions with simultaneous economy and safety of the process.
