Description
Изобретение относитс к металлургии в частности к способам гидрометаллур гической переработки медьсодержащих отходов, и может найти применение при переработке отходов ниобиевой проволоки , покрытой медью, лома электродвигателей и другого медьсодержащего сложного лома. Известен способ извлечени меди из отходов, включающий выщелачивание медноаммиамным раствором сульфата аммони , окисление меди до двухвалентной , кристаллизацию и фильтрацию J. Способ сопровождаетс значительными потер ми аммиака большой продолжительностью процесса и недостаточным извлечением меди в кристаллы (93). Цель изобретени - сокращение продолжительности процесса, расхода ам- миака и повышение выхода меди в кристаллы. Поставленна цель достигаетс тем что в способе извлечени меди из отходов, включающем выщелачивание мед ноаммиачным раствором сульфата а/ мони , окисление меди до двухвалентной , кристаллизацию и фильтрацию, дл выщелачивани используют раствор, содержащий 60-70 г/л неди, и полученный насыщенный медью раствор прюпускают между электродами при напр жении на них 1-2 В. Способ осуществл етс следующим образом. В реактор загружают медьсодержащий лом, затем заливают раствором, предварительно обедненным по содержанию в нем меди до 50-70 г/л и содержащем 220-2 0 г/л сульфата аммони . Соотношение веса медьсодержащего лома к объему раствора поддерживаетс в пределах ). В реакторе протекает процесс растворени меди. Концентраци меди повышаетс до 100-120 г/л. Раствор через сливное отверстие в нижней части реактора с посто нной скоростью подают в катодное пространThe invention relates to metallurgy, in particular, to methods for the hydrometallurgical processing of copper-containing waste, and can be used in the processing of copper-coated niobium wire waste, electric motor scrap and other copper-containing complex scrap. A known method for extracting copper from waste includes leaching with ammonium ammonium sulfate ammonium sulfate, oxidizing copper to divalent, crystallizing and filtering J. The process is accompanied by significant ammonia losses over the long duration of the process and insufficient copper recovery into crystals (93). The purpose of the invention is to reduce the process time, ammonia consumption and increase the yield of copper in the crystals. The goal is achieved by the method of extracting copper from waste, including leaching with ammonium sulfate a / monium solution, oxidation of copper to bivalent, crystallization and filtration, for leaching using a solution containing 60-70 g / l non-solvent, and the resulting saturated copper solution It is pushed between the electrodes with a voltage across them of 1-2 V. The method is carried out as follows. Copper-containing scrap is loaded into the reactor, then it is poured with a solution previously depleted in copper content up to 50-70 g / l and containing 220-2 0 g / l ammonium sulfate. The ratio of the weight of copper-containing scrap to the volume of the solution is maintained within). The process of copper dissolution proceeds in the reactor. The copper concentration rises to 100-120 g / l. The solution through the drain hole in the lower part of the reactor at a constant rate is fed into the cathode space.
