Способ используется в процессе комплексной переработки шламовых полей и отвалов алюминиевого производства. Цель изобретения: переработка шламовых полей и отвалов алюминиевого производства с низким содержанием алюминия без выброса в окружающую среду органических веществ. Сущность изобретения: шламы растворяют серной кислотой в трехкратном объеме от объема обрабатываемых шламов с концентрацией не ниже 90% с разложением органических соединений, дорастворяют соединения железа последующей обработкой концентрированной соляной кислотой, которую добавляют в объеме 10% от объема серной кислоты, а после отделения осадка последовательно осаждают гидроокиси железа, алюминия и магния карбонатами или гидроокисями щелочных и щелочно-земельных металлов, например известью. Положительный эффект: переработка шламов с низким содержанием алюминия и высоким содержанием органических веществ, что решает проблему переработки шламовых полей и отвалов алюминиевого производства без экологически вредных последствий.The method is used in the process of complex processing of sludge fields and dumps of aluminum production. The purpose of the invention: the processing of sludge fields and dumps of aluminum production with low aluminum content without release into the environment of organic matter. The essence of the invention: sludge is dissolved with sulfuric acid in three times the volume of the processed sludge with a concentration of not less than 90% with the decomposition of organic compounds, iron compounds are dissolved by further processing with concentrated hydrochloric acid, which is added in a volume of 10% of the volume of sulfuric acid Hydroxides of iron, aluminum, and magnesium are precipitated with carbonates or hydroxides of alkali and alkaline-earth metals, for example, lime. Positive effect: processing of sludge with low aluminum content and high content of organic substances, which solves the problem of processing sludge fields and dumps of aluminum production without environmentally harmful consequences.
