Изобретение относитс к области гид рометаллургии цинка и может быть использовано в процессе гидрометаллургической переработки окисленных цинксодержащих материалов свинцово-цинкового производства: вельц-окисей, ишаковозгонов , свинцовых пылеи, окисленных цинковых руд, цинковых кеков.The invention relates to the field of zinc hydrometallurgy and can be used in the process of hydrometallurgical processing of oxidized zinc-containing materials of lead-zinc production: Waelz oxides, ishakovsgons, lead dust, oxidized zinc ores, zinc cakes.
известен способ переработки окисленных цинксодержащих материалов евин цово-цинкового производства, например цинковых кеков, включающий приготовление пульпы исходного продукта и выщелачивание путем контактировани с ионитом с последующей десорбцией цинка 1, вл ющийс наиболее близким по технической сущности и достигаемому эффекту к предложенному способу . По этому способу пульпу miHKOвого кека контактируют со слабокислотнкм карбоксильным катионообменником КВ-2-7П при рН 4,4-6,0, а затем цветные металлы дёсорбируют сернокислым раствором.There is a known method for processing oxidized zinc-containing materials for evinous zinc production, for example, zinc cake, which includes preparation of raw material pulp and leaching by contacting with an ion exchanger followed by zinc desorption 1, which is the closest in technical essence and effect to the proposed method. According to this method, the miHKO cake slurry is contacted with weakly acidic carboxylic acid KV-2-7P cation at pH 4.4-6.0, and then non-ferrous metals are adsorbed with sulphate solution.
Этот способ обеспечивает извлечение водораствори1«;1Х форм цветных металлов и частичное извлечение кислото растворимых форм, однако, так как максимальна емкость карбоксильного катионита реализуетс при рН 4,46 ,0, то требуетс значительный расход нейтрализатора (до 25% от веса кека) дл поддержани высоких значений рН и, кроме того, снижаетс извлечение кислоторастворимых форм цинка , кадми и меди из кеков.This method provides for the removal of water-soluble 1 "; 1X forms of non-ferrous metals and partial extraction of acid-soluble forms, however, since the maximum capacity of the carboxyl cation exchanger is realized at pH 4.46, 0, a significant consumption of neutralizer is required (up to 25% by weight of cake) to maintain high pH values and, in addition, the recovery of acid soluble forms of zinc, cadmium and copper from cakes is reduced.
Целью изобретени вл етс повышение степени извлечени кислоторастворимых форм цинка, кадми и меди The aim of the invention is to increase the recovery of acid-soluble forms of zinc, cadmium and copper.
10 и удешевление процесса за счет снижени расхода нейтрализатора.10 and cheaper process by reducing the consumption of the neutralizer.
Поставленна цель достигаетс тем, что в способе переработки окисленных цинксодержащих материешов свинцово15 цинкового производства, например цин-; ковых кеков, включающем приготовление пульпы исходного продукта и выщелачивание путем контактировани с иони том с последующей десорбцией цинка, This goal is achieved by the fact that in the method of processing oxidized zinc containing lead materials 15 of zinc production, for example, zinc; cakes, including the preparation of the raw material pulp and leaching by contact with ionite, followed by desorption of zinc,
20 выщелачивание ведут с использованием в качестве ионита амфотерной ионообменной АМФ-2-7П с ионогенной группой20 leaching is carried out using amphoteric ion-exchange AMP-2-7P with an ionic group as an ion exchanger.
