Description
Дл извлечени цинка из коллективных медно-цинковых концентратов на медных заводах примен етс пирометаллургический снособ. Известен также гидрометаллургический способ выщелачивани мсдно-цицковых концентратов после сульфатизирующего обжига в кип щем слое с последующим электроосаждением меди и цинка из растворов.Pyrometallurgical removal is used to extract zinc from collective copper-zinc concentrates in copper plants. Also known is a hydrometallurgical method of leaching MSD concentrates after sulfatizing calcination in a fluidized bed, followed by electrodeposition of copper and zinc from solutions.
Описываемый способ предусматривает вначале обжиг коллективных концентратов с карналлитом при температурах не выше 280- 300° с посто нным или периодическим перегребанием щихты при доступе воздуха с последующим выщелачиванием огарка при температуре 60-70°, в результате которого в раствор переходит подавл юща часть цинка, кадми , хлора и часть серы, а в кеке от выщелачивани остаетс (после его промывки) золото, серебро, селен, железо, индий , медь и другие метаиТлы.The described method involves first firing collective concentrates with carnallite at temperatures not higher than 280-300 ° C with a constant or periodic re-dressing of the mixture under air access and subsequent leaching of the cinder at 60-70 ° C, as a result of which the bulk of zinc, cadmium , chlorine and part of sulfur, and in the leaching cake, gold, silver, selenium, iron, indium, copper and other metachlores remain (after washing).
Дальнейша переработка раствора , содержащего цинк и кадмий.Further processing of the solution containing zinc and cadmium.
производитс ооычным путем гидролитического осаждени этих металлов, а кек подвергаетс обычной плавке.It is produced by conventional hydrolytic precipitation of these metals, and the cake is subjected to ordinary smelting.
Особенность описываемого способа заключаетс в том, что цинк сразу в голове процесса выводитс из концентрата в раствор, тогда как в процессе плавки цинк переводитс в шлак, а при гидрометаллургическом способе цинк переходит в раствор вместе с медью и другими металлами. Этот способ позвол ет повысить извлечение цинка из ко,1лективных концентратов и достигнуть разделени но только меди от цинка, но и других по.юзных мета.ч.юв.The peculiarity of the described method is that zinc is immediately removed from the concentrate into solution at the head of the process, while in the smelting process, zinc is converted into slag, and in the hydrometallurgical method, zinc goes into solution with copper and other metals. This method makes it possible to increase the extraction of zinc from organic concentrates and to achieve separation not only of copper from zinc, but also of other well-known meta.ch.
