Description
Известны способы плавки пылей свинцового и других производств в электрической печи с сульфатом натри и углем и обезмелсивани чернового свинца, полученного в процессе шахтной плавки. Однако существующие способы переработки свинецсодержащих пылей не обеспечивают комплексного извлечени металлов, влекут за собой больщие потери серной кислоты и не позвол ют полностью вывести мышь к из процесса.Known methods for smelting lead dust and other industries in an electric furnace with sodium sulphate and coal and removing the rough lead obtained in the mine smelting process. However, the existing methods for processing lead-containing dusts do not provide complex metal extraction, entail large losses of sulfuric acid and do not allow the mouse to be completely removed from the process.
Применение описываемого способа исключает указанные недостатки. Отличительна особенность его заключаетс в том, что в исходную пыль ввод т 20-25% сульфата натри , 5-10% свинцового сульфидного концентрата и 4-5% углеродсодержащего восстановител и плав т при 1050-1150° в электрической печи. В результате такой плавки получают черновой свинец; расплав тиосолей, содержащий малые, редкие металлы , цинк и медь; кадмиевые возгоны. Полученный черновой свинец подвергают рафинированию, а кадмиевые возгоны перерабатывают по известной сернокислотной схеме. Полученные тиосоли в твердом или расплавленном виде поступают на обезмеживание чернового свинца шахтной плавки. Свинец, после обезмеживани , поступает на дальнейшее рафинирование, а расплав.тиосолей, обогащенный в процессе обезмеживани медью; цинком,--мышь ком и редкими металлами, -подвергают гидрометаллургической обработке-водному выщелачиванию . В процессе водного выщелачивани мыщь к...и натрий переход т в раствор, из которого мыщь к цементируют алюминием, а натрий извлекают в виде соды путем карбонизации раствора после отделени мыщь ка. Выделенный после водного выщелачивани расплава тиосолей кек, содержащий цинк, медь, индий, теллур, селен, галий, перерабатывают известным способом - сульфатизацией серной кислотой.The use of the described method eliminates the indicated disadvantages. Its distinctive feature is that 20-25% of sodium sulfate, 5-10% of lead sulfide concentrate and 4-5% of carbon-containing reductant are introduced into the initial dust and melted at 1050-1150 ° in an electric furnace. As a result of this melting get rough lead; a melt of thiosols containing small, rare metals, zinc and copper; cadmium sublimates. The resulting crude lead is subjected to refining, and cadmium sublimates are processed according to the known sulfuric acid scheme. The resulting thiosol in solid or molten form is fed to the de-mixing of the rough lead of the smelting shaft. Lead, after deceleration, is fed to further refining, and molten thi salts, enriched in the process of deceleration, with copper; zinc, mouse and rare metals, are hydrometallurgical treated with water leaching. In the process of water leaching, the mice ... and the sodium is transferred into a solution, from which the mouse is cemented with aluminum, and the sodium is extracted as soda by carbonizing the solution after separating the mouse. Selected after water leaching of the melt with thiosols, the cake containing zinc, copper, indium, tellurium, selenium, and gallium is processed in a known manner by sulfatization with sulfuric acid.

Описываемый способ может быть использован дл переработки пылей шахтных и агломерационных цехов свинцовоплавильных заводов , пылей конверторных переделов медных штейнов, пылей олов нных заводов, возгонов фьюминг и вельц-печей, возгонов циклонно-возвешенной плавки, свинцовых кеков и шлаков сернокислотных заводов.The described method can be used for processing mine dusts and sinter plants lead smelter, dusts redistribution of converter matte copper, tin dusts nnyh plants sublimates fuming and the Waelz kilns, sublimates vozveshennoy cyclone-melting, lead slags and residues from sulfuric acid plants.
