FIELD: metallurgy.SUBSTANCE: reduction is performed with hydrogen generated in solution; at that, reduction is catalysed with reduced metal itself, which is contained in finely dispersed state. Reduction process is performed in multi-pass reactor at variable pressure that is changed with frequency of 1-5 Hz from maximum to minimum values of 8 kg/cmto 0.25 kg/cm. Extraction plant of metals capable of hydrogen absorption from solutions includes dosing device, modified displacement pump, electrolyser for hydrogen generation and multi-pass reactor in the form of labyrinth.EFFECT: simplifying the process and improving the purity of extracted metal.10 cl, 9 dwg, 8 tbl, 4 ex |
