FIELD: metallurgy. ^ SUBSTANCE: invention refers to method of extraction of at least one metal compound and/or its element out of liquid mixture or out of mixture containing catalyst and/or residuals of catalyst after homogeneous catalysed reaction. The method includes contacting of the said mixture with heteropolyacid or with anion of heteropolyacid, at that volume of heteropolyacid or anions of heteropolyacid consists at least 0.1 of equivalent with obtaining a sediment, at that, this sediment is practically non-soluble in the said reaction mixture and containing heteropolyacid or anion of heteropoliacid and compound of metal and/or its element; the method also includes reduction of the reaction mixture. ^ EFFECT: upgraded efficiency of process. ^ 41 cl, 3 ex |
