(54) СПОСОБ ПОЛУЧЕНИЯ ЗАКИСИ МЕ/да(54) METHOD OF OBTAINING IK OXIDE / yes
- I. Изобретенне относитс к металлургни цветных металлов и может быть нс пользовано дл получени закиси меди из медьсодержащих растворов. Известен способ получени закиси меди включающий восстановление комплексных а1шиакатов двухвалентной vie дй до соответствующих а14миакатов одновалентной меди, обработки последних раствором едкого натра и последующее отделение продукта С3 Однако указанный способ многостади вн и не позвол ет получать продукт высокого качества. Наиболее близким к описываемому способу по технической сущности и до стигаемому результату вл етс способ получени закиси меди, включающи взаимодействие раствора сернокислой меди с металлом-восстановителем цинковьм порошком, дозируемым в течение процесса со скоростью 0,4-0,5 кг/мин в присутствии ионов хлора при рН 3,0-3,5 с последующим отделением и сушкой продукта Недостаток данного способа заключаетс в том, что наличие в реакционной смеси ионов хлора ведет к образовашло полухлористой меди, из-за чего невоэможно получить чистый продукт с ВЫСОКШ1 содержанием основного вещества, а также сложность осуществлени процесса из-за равномерной и точной дозировки металла. Цель изобретени - повышение содержани основного вещества в продукте и упрощение процесса. Поставленна цель достигаетс тем, что согласно способу получени закиси меди, включающему взаимодействие раствора сернокислой меди с металлом восстановителем - медным порошком с размером частиц 2-50 мкм в количестве , обеспечивающем массовое от1ношение его к меди, содержащейс в ipacTBOpe, равном (0,85-1,):, при- I. The invention relates to non-ferrous metal mills and may not be used to obtain copper oxide from copper-containing solutions. A known method for producing cuprous oxide involves the reduction of complex bivalent vie dy aluminate to the corresponding copper monovalent a14miatate, treatment of the latter with caustic soda solution and subsequent separation of the C3 product. However, this multi-stage method does not allow to obtain a high-quality product. The closest to the described method to the technical essence and achievable result is a method of obtaining copper oxide, including the interaction of a solution of copper sulfate with a metal-reducing zinc powder, dosed during the process at a rate of 0.4-0.5 kg / min in the presence of ions chlorine at pH 3.0-3.5, followed by separation and drying of the product. The disadvantage of this method is that the presence of chlorine ions in the reaction mixture leads to the formation of copper chloride, which makes it impossible to obtain a pure product. t with high content of the main substance, as well as the complexity of the process due to the uniform and accurate dosage of the metal. The purpose of the invention is to increase the content of the main substance in the product and simplify the process. The goal is achieved by the fact that according to the method of producing cuprous oxide, which includes the interaction of a copper sulphate solution with a reducing metal — a copper powder with a particle size of 2-50 microns in an amount that ensures its mass ratio to copper contained in ipacTBOpe equal to (0.85 - 1,) :, with
