Claims (6)

1. Способ очистки содержащих металлы растворов, включающий нейтрализацию раствора, восстановление присутствующего Fе(III) и удаление входящего растворенного цинка, отличающийся тем, что входящий содержащий металлы раствор нейтрализуют с использованием магнетита и/или металлического железа, входящее железо (III) восстанавливают до железа (II) с помощью добавления металлического железа, входящие тяжелые металлы осаждают добавлением осаждающего количества сульфида, таким образом осажденные сульфиды металлов восстанавливают с помощью фильтрации, раствор по выбору подвергают операции ионообмена для перевода входящего цинка в несвязанную в комплекс форму, после чего цинк выделяют в виде карбоната цинка, железо (II) в оставшемся растворе окисляют до железа (III), после чего раствор используют как таковой или подвергают дальнейшей обработке в целях повышения содержания металла для использования раствора в нужных целях.1. A method of cleaning metal-containing solutions, including neutralizing the solution, recovering the present Fe (III) and removing the incoming dissolved zinc, characterized in that the incoming metal-containing solution is neutralized using magnetite and / or metallic iron, the incoming iron (III) is reduced to iron (II) by adding metallic iron, incoming heavy metals are precipitated by the addition of a precipitating amount of sulfide, so the precipitated metal sulfides are reduced by a filter In this case, the solution is optionally subjected to ion exchange to convert the incoming zinc into a form unbound in the complex, after which zinc is isolated in the form of zinc carbonate, iron (II) in the remaining solution is oxidized to iron (III), after which the solution is used as such or subjected to further processing in order to increase the metal content to use the solution for the right purpose. 2. Способ по п. 1, отличающийся тем, что способ осуществляют при температуре 10 - 80oС.2. The method according to p. 1, characterized in that the method is carried out at a temperature of 10 - 80 o C. 3. Способ по пп. 1 и 2, отличающийся тем, что кристаллы гептагидрата железа (II) используют в качестве исходного материала, содержащего металл раствора. 3. The method according to PP. 1 and 2, characterized in that the crystals of iron (II) heptahydrate are used as a starting material containing a metal solution. 4. Способ по п. 3, отличающийся тем, что способ осуществляют при температуре 60oС.4. The method according to p. 3, characterized in that the method is carried out at a temperature of 60 o C. 5. Способ по п. 1, отличающийся тем, что гептагидрат железа (II) добавляют с целью повышения содержания железа в очищенном растворе. 5. The method according to p. 1, characterized in that the iron (II) heptahydrate is added in order to increase the iron content in the purified solution. 6. Способ по п. 1, отличающийся тем, что раствор нейтрализуют до рН около 4,5. 6. The method according to p. 1, characterized in that the solution is neutralized to a pH of about 4.5.
