Abstract

1. Способ извлечения висмута и германия из масло-абразивных отходов, включающий солянокислое выщелачивание висмута, электроизвлечение из маточного раствора висмута и выделение соединения германия, отличающийся тем, что в раствор выщелачивания добавляют поверхностно-активное вещество, а из абразиво-германийсодержащего осадка маточного раствора осуществляют отгонку четыреххлористого германия в парах соляной кислоты без предварительного удаления органических соединений.2. Способ по п.1, отличающийся тем, что в качестве поверхностно-активного вещества используют техническую смесь оксиэтилированных алкилфенолов с торговым названием «Неонол» марки АФ 9-6 в концентрации 0,01-0,1 мас.%.1. A method of extracting bismuth and germanium from oil-abrasive waste, including hydrochloric leaching of bismuth, electro-extraction from the mother liquor of bismuth and the isolation of a germanium compound, characterized in that a surfactant is added to the leaching solution, and from the abrasive-germanium-containing sediment of the mother liquor is carried out distillation of germanium tetrachloride in hydrochloric acid vapors without preliminary removal of organic compounds. 2. The method according to claim 1, characterized in that the technical mixture of ethoxylated alkylphenols with the trade name "Neonol" brand AF 9-6 in a concentration of 0.01-0.1 wt.% Is used as the surfactant.
