Description

Изобретение относитс  к электролитическому способу рафинированной переработки ретортного серебристого свинца.This invention relates to an electrolytic method for the refined processing of retort silver lead.

В насто щее врем  после обессеребрени  свинца получаетс  цинкова  пена, котора  подвергаетс  сушке н дистилл ции. В результате последней операцип по вл ютс  два продукта - цинковые возгоны и богатый ретортный свннец.At present, after lead desulfurization, zinc foam is obtained, which is subjected to drying and distillation. As a result of the latter, two products emerge - zinc sublimates and a rich retort svnets.

РетортныГ) свинец, выход которого составл ет около от общего количества получаемого металла, подвергаетс  купел ции. При этой операции около свинца переходит в пары и пыль, а 80/ окисл етс  и I виде глета удал етс  из печеП. Глет направл етс  и niaxTHyio плавку в качестве оборотного продукта, С глетом из печи удал етс  около 5% растворенного в нем серебра. Процесс купел ции требует применени  пылеулавителей большого объема, значительного расхода огнеупоров и св зан с т желыми услови ми труда дл  обслуживающего персонала.Retort iron lead, the yield of which is about the total amount of the metal produced, is subject to purchase. During this operation, about lead and dust are vaporized, and 80 / is oxidized and I of the form of wood is removed from the furnace. The glaze is guided and the niaxTHyio is smelted as a circulating product, about 5% of silver dissolved in it is removed from the furnace with the glaze. The bathing process requires the use of a large volume of dust collectors, a significant consumption of refractories and is associated with difficult working conditions for the staff.

Новый процесс в значительной степени ликвидирует перечисленные недостатки. Сущность его состоит в следующем: полученный после процесса дистилл ции богатый свииец разливаетс  в форму анодов, которые завешиваютс  в электролитную ванну. Электролитом в последней служит раствор кремнефтористоводородной , амидо-нли фенолсульфоновой кислоты, а катодами- матричные листы из рольного свинца.The new process largely eliminates the listed disadvantages. Its essence is as follows: the rich swine obtained after the distillation process is poured into the form of anodes, which are hung in an electrolytic bath. The electrolyte in the latter is a solution of fluorosilicic acid, amido-nli of phenolsulfonic acid, and the cathodes are matrix sheets of roll lead.

В результате э.тектролиза около 85л свинца из анодов осаждаетс  на катоде в виде чистого металла, а свинца в смеси с золотом и серебром переходит в шлам, подвергающийс  плавке и купел ции обычным способом. Полученный катодный свинец загружаетс  в один из носледних котлов рафинированного цеха, что повышает выход металла на 1,5-2,0%. При этом операци  купелировани  уменыпаегс  в 5- 6 раз, значительно облегчаютс  услови  труда и повышаемс  извлечение свинца и серебра. № 106676- Предмет изобретени  Способ переработки серебристого свинца, отличающийс  тем, что 2серебристый свинец вместо купел ции подвергаетс  элекфо-лизу в кремнефтористоводородном или сульфаминовом электролите.As a result of this electrolysis, about 85 liters of lead from the anodes are deposited on the cathode in the form of a pure metal, and lead in a mixture with gold and silver goes into sludge, which is melted and bought in the usual way. The resulting cathode lead is loaded into one of the pre-cold boilers of the refined workshop, which increases the metal yield by 1.5-2.0%. In this case, the cupel operation decreases by a factor of 5 to 6, labor conditions are greatly facilitated, and lead and silver extraction are increased. No. 106676. Object of the Invention A silver lead processing method, characterized in that 2 silver lead, instead of buying, is electrolysed in hydrogen fluoride fluoride or sulfamine electrolyte.
