Способ извлечени меди из окислеиных или смешанных руд или хвостов обогатительных фабрикThe method of extracting copper from oxidized or mixed ores or tailings of the beneficiation plants
За влено 28 апрел 1940 г. в Наркомцветмет за Л 32314 (302234) Опубликовано 31 марта 1944 годаFiled April 28, 1940 in Narkomtsvetmet for L 32314 (302234) Published March 31, 1944
В современной практике переработка окисленных и смешанных {содержащих медь в форме окислов , сульфидов, карбонатов и т. д.) руд производитс двум способами; пирометаллургическим и гидрометаллургическим .In modern practice, the processing of oxidized and mixed {containing copper in the form of oxides, sulphides, carbonates, etc.) ores is carried out in two ways; pyrometallurgical and hydrometallurgical.
В первом случае богатые медью окисленные или смешанные руды или концентраты, полученные в результате флотационного обогаш,ени , плав тс в шахтных или отражательных печах на штейн или черновую медь.In the first case, copper-rich, oxidized or mixed ores or concentrates resulting from flotation heating, are melted in a shaft or reflective furnace to matte or blister copper.
При гидрометаллургических методах дл извлечени медк из окисленных или смешанных руд в качестве растворител примен ют серную кислоту, кислые растворы сульфата окиси железа, аммиачные растворы и т. д. Осаждение меди из растворов производитс посредством железа, электролизом, нагреванием растворов и т. д.In hydrometallurgical methods, sulfuric acid, acidic solutions of iron oxide sulfate, ammonia solutions, etc. are used as solvents to extract meds from oxidized or mixed ores. Copper is precipitated from solutions by iron, electrolysis, heating solutions, etc.
Вопросы флотациопного обогащени окисленных и смешанных руд уже давно привлекали внимание исследователей, но до самого последнего времени процесс не давал удовлетво.рительных результатов.The issues of flotation enrichment of oxidized and mixed ores have long attracted the attention of researchers, but until very recently the process did not give satisfactory results.
При пр мом флотационном обогащении окисленных; и смешанных руд извлечение меди колеблетс в пределах 60-70% против 85-95% при обогащении сульфидных руд.With direct flotation enrichment of oxidized; and mixed ores, copper recovery ranges from 60-70% versus 85-95% with the enrichment of sulphide ores.
Такие огромные потери меди изза несоверщепства пр мого флотационного метода заставили обратитьс к более сложным комбинированным процессам. В качестве такого комбинированного процесса предлагалось выщелачивать медь серной кислотой с осаждением растворённой меди губчатым железом или железным скрапом с последующей флотацией. Однако процесс с употреблением губчатого железа, вследствие затруднений с его производством , распространени в промышленности не получил, а применение железного скрапа вызывает необходимость в установке дорогой и громоздкой аппаратуры, что сильно усложн ет и затрудн ет процесс.Such huge copper losses due to the non-digestion of the direct flotation method made it necessary to turn to more complex combined processes. As such a combined process, it was proposed to leach copper with sulfuric acid with precipitation of dissolved copper with sponge iron or iron scrap, followed by flotation. However, the process with the use of sponge iron, due to difficulties with its production, has not been distributed in industry, and the use of iron scrap makes it necessary to install expensive and cumbersome equipment, which greatly complicates and complicates the process.
