(54) СПОСОБ ИЗВЛЕЧЕНИЯ ЦИНКА ИЗ СЕРНОКИСГШХ РАСТВОРОВ ЭЛЕКТРОЛИЗС(54) METHOD FOR EXTRACTING ZINC FROM SERIOUS SUSTAINABLE ELECTROLYSIS SOLUTIONS
Изобретение относ тс к цветной 1«етал ургии, в частности к извлечению цинка электролизом из сернокислы растворов, , Известны способы извлечени цинка из сернокислых растворов электролизо с введением в электролит таких добавок , как желатин, гуммиарабик, оедко стекло, различные сорта кле ПЗ Введение добавок улучшает показатели процесса электролиза. Наиболее близким по технической сущности и достигаемому результату вл етс способ извлечени цинка из. сернокислых.растворов злектролизом с введением в электролит добавки мез дрового кле в количестве 20-60 мг/лШ Однакс} введение всех перечисленных добавок недостаточно повьшает выход по току, что приводит к непроизводительным затратам электрознергии . Цель изобретени -.повьшение выхода по току при извлечении цинка злектролизом из сернокислых растворов. Поставленна цель достигаетс тем, что согласно способу извелечени цинка из сернокислых растворов злектролизом с введением в электролит добавки , в качестве последней ввод т ингибитор коррозии ХОСП-10 в количестве 10-20 мг/л. ТУ на ХОСП-10 составлены и оформлены в соответствии с ГОСТ 2.114-70, ГОСТ 2.115-70 и ОСТ 6-35-1-72. Введение ХОСД-10 в электролит обеспечивает достижение более высокого выхода по току цинка, что влечет за Ьобой экономию электроэнергии. П р и м е р . Из сернокислого электролита состава цинк 50 г/л; серна кислота 135 г/л; железо 30 мг/л; медь0,3 мг/л; кобальт 2 мг/л; сурьма и,3 мг/л электролитически осаждают цинк.The invention relates to colored 1 "plastic, in particular, to the extraction of zinc by electrolysis from sulphate solutions. Known methods for the extraction of zinc from sulphate solutions of electrolysis with the introduction of such additives as gelatin, gum arabic, olecine glass, various grades of adhesive PZ into the electrolyte. Introduction of additives improves the performance of the electrolysis process. The closest in technical essence and the achieved result is a method of extracting zinc from. sulfate solutions by electrolysis with the introduction of an additive to the electrolyte of an additive of mesarwood glue in the amount of 20-60 mg / lN of Odax} the introduction of all the listed additives does not sufficiently increase the current efficiency, which leads to an unproductive expenditure of electrical power. The purpose of the invention is to increase the current output when zinc is extracted by electrolysis from sulphate solutions. This goal is achieved by the fact that according to the method of extracting zinc from sulfuric acid solutions by electrolysis with the introduction of an additive into the electrolyte, the corrosion inhibitor XOSP-10 in an amount of 10-20 mg / l is used as the last. TU on HOSP-10 are made and decorated in accordance with GOST 2.114-70, GOST 2.115-70 and OST 6-35-1-72. The introduction of HOSD-10 into the electrolyte ensures the achievement of a higher current efficiency of zinc, which leads to energy savings. PRI me R. Of the sulfate electrolyte composition of zinc 50 g / l; sulfuric acid 135 g / l; iron 30 mg / l; copper 0.3 mg / l; cobalt 2 mg / l; antimony and 3 mg / l electrolytically precipitate zinc.

Все опыты электролиза провод тХОСП-10 ввод т как в раствор, содерпри , плотности тока 600 А/м.жащийс в электролизере, так и в нейПосто нство состава пддцерживаюттральн1лй раствор.All electrolysis experiments were performed with xHOSP-10, both in the solution, the current density of 600 A / m, which was found in the cell, and in its composition. The composition of the electrolytic cell was controlled by a neutral solution.
путем непрерьшной подачи в электролитРезультаты опытов по вли нию разнейтрального раствора сульфата цинка5 личных количеств добавки ХОСП-10 на с концентрацией 140 г/л,выход по току цинка приведены втайИсследуемое количество добавкилице.by continuous feeding into the electrolyte, the results of experiments on the effect of different neutral solution of zinc sulphate, 5 personal amounts of the HOSP-10 additive on with a concentration of 140 g / l, the current output of zinc are given in the study.
Как видно из таблицы, введение в электролит в качестве добавки ингибитора коррозии XOCn-iO позвол ет увеличить выход по току цинка.As can be seen from the table, the introduction of XOCn-iO into the electrolyte as an additive to the corrosion inhibitor allows an increase in the zinc current efficiency.
Учитыва , что в промьшшенном произ- водстве процесс извлечени цинка электролизом из сернокислых растворов продолжаетс 24 ч, лабораторные исследовани проводились такой же продолжительности iConsidering that in industrial production the process of zinc extraction by electrolysis from sulphate solutions lasts 24 hours, laboratory studies were carried out for the same duration i
Использование предлагаемого способа извлечени цинка электро- , лизом из сернокислых растворов с введением в электролит добавки ХОСП-Ю обеспечивает по сравнению с известными повьшение выхода по току цинка в среднем на 3% и, следовательно , снижение, удельного расхода электроэнергии на 100 кВт/ч, а также использование синтетического реагента взамен дефицитного кле животного происхождени .The use of the proposed method for the extraction of zinc by electrolysis from sulfuric acid solutions with the introduction of the HOSP-S additive to the electrolyte provides an increase in current output of zinc by an average of 3% compared to the known and, consequently, a decrease in the specific energy consumption per 100 kW / h, and the use of synthetic reagent instead of scarce glue of animal origin.
