FIELD: metallurgy.
SUBSTANCE: invention relates to extraction of metals from flow rich in hydrocarbons and carbon residues with the help of treatment section. Proposed method comprises feeding of said flow to extraction by its mixing with appropriate hydrophilising agent to kill hydrophobic properties of said flow. Mix of said flow and said agent are fed so separation of liquid phase containing major portion of hydrophilising agent and hydrocarbons precipitated from solid phase. Separated solid phase is dried at 350°C to remove medium-light hydrocarbon components. Separated solid phase, preferably dried, is fed for leaching by alkaline solution in the presence of air and/or oxygen, possibly, in the presence of emulsifier or its precursor. Then, leached mix is fed for separation to remove solid residue from leach liquor.
EFFECT: higher yield of valuable metals and hydrocarbons.
