Description
Предложенный способ относитс к области электролиза в цветной металлургии.The proposed method relates to the field of electrolysis in non-ferrous metallurgy.
Известен способ получени нерастворимых анодов -на основе свинца и кобальта, при котором кобальт вводитс в свинец с помощью третьего компонента, в частности талли . Однако таллий с трудом сплавл етс с кобальтом , причем происходит интенсивное испарение и окисление талли , что вызывает усложнение процесса. Кроме того, введение в аноды третьего компонента приводит к загр знению катодного продукта нежелательными примес ми.A known method for producing insoluble anodes, on the basis of lead and cobalt, in which cobalt is introduced into lead by means of a third component, in particular thallium. However, thallium is difficult to fuse with cobalt, and intense evaporation and oxidation of thallium occurs, which complicates the process. In addition, the introduction of the third component into the anodes leads to contamination of the cathode product with undesirable impurities.
Предложенный способ позвол ет получать нерастворимые аноды из свинца, содержащего кобальт, без .примеси третьего компонента, благодар чему достигаетс более высокое качество катодного продукта. Длительные испытани показали, что стойкость анодов, изготовленных предложенным способом, в трип ть ра превышает стойкость свинцово-серобр ных анодов, примен емых обычно при электролизе сернокислых растворов.The proposed method allows to obtain insoluble anodes from lead containing cobalt, without impurities of the third component, due to which a higher quality of the cathode product is achieved. Long-term tests have shown that the resistance of the anodes made by the proposed method triple exceeds the resistance of lead-sulfur-free anodes, usually used in the electrolysis of sulphate solutions.
По .предложенному способу дл повышени чистоты анодов кобальт ввод т в расплавленный свинец цементацией из расплава солей металлов.According to the proposed method for increasing the purity of the anodes, cobalt is introduced into the molten lead by cementation from a melt of metal salts.
Оптимальный состав солевого электролита (в %): хлористый кобальт 2, хлористый натрий 64, хлористый динк 34. Оптимальна концентраци кобальта в свинце 0,03-0,05%.The optimal composition of the salt electrolyte (in%): cobalt chloride 2, sodium chloride 64, dink chloride 34. The optimal cobalt concentration in lead is 0.03-0.05%.
Предмет изобретени Subject invention
Способ .получени нерастворимых свинцовых анодов, содержащих кобальт, дл электролиза сернокислых растворов, отличающийс тем, что, с целью повышени чистоты анодов, кобальт ввод т в расплавленный свинец цементацией из расплавов солей металлов .The method of obtaining insoluble lead anodes containing cobalt for electrolysis of sulphate solutions, characterized in that, in order to increase the purity of the anodes, cobalt is introduced into the molten lead by cementation from molten metal salts.
