Claims (5)

1. Способ комплексной переработки металлургических отходов производства, включающий слив отработанного расплава титановых хлораторов в воду, концентрирование пульпы путем циркуляции, обработку высокомолекулярным флокулянтом, сгущение пульпы, осаждение из осветленных растворов оксигидратов металлов последовательно в три стадии: на первой при рН 3,5-5,0 с отделением образующегося осадка гидроксида хрома, алюминия и скандия от раствора, проведения на второй стадии осаждения в присутствии окислителя при рН 2,5-3,5 в течение 20-50 ч с отделением осадка, и на третьей стадии - при рН 9,5-11,0, отличающийся тем, что в пульпу при ее циркуляции и концентрировании вводят сульфит натрия в количестве 5-15 г/дм3, после циркуляции обрабатывают раствором хлорида бария в количестве 10-20 г/дм3, а перед осаждением оксигидратов металлов на третьей стадии раствор предварительно смешивают с медь(II)-содержащим раствором от выщелачивания плава процесса очистки технического тетрахлорида титана от окситрихлорида ванадия медным порошком, осадок отфильтровывают, промывают, сушат и прокаливают при 400-700°С.1. A method of complex processing of metallurgical production wastes, including the discharge of the spent titanium chlorine melt into water, pulp concentration by circulation, treatment with a high molecular weight flocculant, pulp thickening, precipitation of metal oxyhydrates from clarified solutions in three stages in succession: in the first at pH 3.5-5 , 0 with the separation of the precipitate of chromium hydroxide, aluminum and scandium from the solution, conducting in the second stage of deposition in the presence of an oxidizing agent at a pH of 2.5-3.5 for 20-50 hours with separation of cage, and in the third stage - at a pH of 9.5-11.0, characterized in that sodium sulfite is introduced into the pulp during its circulation and concentration in an amount of 5-15 g / dm 3 , after circulation it is treated with a solution of barium chloride in an amount of 10 -20 g / dm 3 , and before the precipitation of metal oxyhydrates in the third stage, the solution is pre-mixed with a copper (II) -containing solution from leaching the melt of the process of purification of technical titanium tetrachloride from vanadium oxytrichloride with copper powder, the precipitate is filtered off, washed, dried and calcined at 400 -700 ° C. 2. Способ по п.1, отличающийся тем, что сгущенную пульпу после ее циркуляции, концентрирования и обработки растворами Na2SO3 и BaCl2 фильтруют, осадок промывают раствором и/или суспензией, содержащей 150-200 г/дм3 MgCl2, высушивают с минеральными веществами, содержащими оксид магния, после чего термообрабатывают, прессуют и формуют.2. The method according to claim 1, characterized in that the thickened pulp after its circulation, concentration and treatment with Na 2 SO 3 and BaCl 2 solutions is filtered, the precipitate is washed with a solution and / or suspension containing 150-200 g / dm 3 MgCl 2 , dried with minerals containing magnesium oxide, after which it is heat treated, pressed and molded. 3. Способ по п.1, отличающийся тем, что осаждение оксигидратов металлов ведут раствором гидроксида натрия с концентрацией 80-120 г/дм3.3. The method according to claim 1, characterized in that the deposition of metal oxyhydrates is a solution of sodium hydroxide with a concentration of 80-120 g / DM 3 . 4. Способ по п.1, отличающийся тем, что сульфит натрия вводят в пульпу при ее циркуляции в виде водного раствора с концентрацией 50-100 г/дм3.4. The method according to claim 1, characterized in that the sodium sulfite is introduced into the pulp during its circulation in the form of an aqueous solution with a concentration of 50-100 g / DM 3 . 5. Способ по п.1, отличающийся тем, что осаждение оксигидрата железа на второй стадии ведут до остаточной концентрации железа(II) в растворе 3-10 г/дм3.5. The method according to claim 1, characterized in that the deposition of iron oxyhydrate in the second stage leads to a residual concentration of iron (II) in a solution of 3-10 g / DM 3 .
