Из анодного пространства электролизера отвод т анолит, который затем охлаждают до 25 - 35°С и направл ют на фильтрацию, после чего анолит поступает в бак-накопитель, где его смешивают с отработанным электролитом до получени рабочего электролита, который подают на дополнительную фильтрацию, а затем направл ют в электролизер. 1 табл.This invention relates to non-ferrous metallurgy and can be used in the electro-refining of copper. The aim of the invention is to increase the yield of foil. The anolyte is removed from the anode space of the electrolyzer, which is then cooled to 25 - 35 ° C and sent to filtration, after which the anolyte enters the storage tank, where it is mixed with the spent electrolyte to produce a working electrolyte, which is fed to additional filtration, then sent to the electrolyzer. 1 tab.
Description
Изобретение относитс к цветной металлургии и может быть использовано при электрорафинировании меди.This invention relates to non-ferrous metallurgy and can be used in the electro-refining of copper.
Цель изобретени - повышение выхода годной фольги.The purpose of the invention is to increase the yield of foil.
Электроосаждение медной фольги осу- щестл ют из сернокислого электролита состава г/л: медь 52 - 56; серна кислота 95 - 100 при температуре 38 - 43°С. Анолит сливают из анодного пространства, затем охлаждают до 25 - 35°С. При этом выдел етс часть мелкодисперсной меди, котора частично цементируетс на кристаллах медного купороса, основное количество ее улавливаетс , например, в предварительно установленной ловушке, а затем фильтрует: с . Охлажденный и очищенный анолит поступает в бак-накопитель, где он смешиваетс с отработанным элеткролитом до получени рабочего электролита. Далее рабочий электролит подают на фильтрацию дл очистки его от механических взвешенных частиц и затем он поступает в электро- лиэер дл получени медной фольги.The electrodeposition of copper foil is made of g / l sulfuric acid electrolyte: copper 52–56; sulfuric acid 95 - 100 at a temperature of 38 - 43 ° C. The anolyte is drained from the anode space, then cooled to 25 - 35 ° C. In this case, a part of fine copper is separated, which is partially cemented on crystals of copper sulphate, its main amount is caught, for example, in a pre-installed trap, and then filters: c. The cooled and purified anolyte enters the storage tank, where it mixes with the spent electrolyte to produce a working electrolyte. Next, the working electrolyte is fed to the filtration to clean it from mechanical suspended particles and then it enters the electrolyte to form a copper foil.
Результаты опытов представлены в таблице .The results of the experiments are presented in the table.
Из данных таблицы следует, что при введении операции охлаждени анолита перед фильтрацией до 25 - 35°С и дополнительной фильтрации рабочего электролита выход годной фольги составил 87 - 98,23 %, т.е. в сравнении с прототипом, где выход годной продукции составл ет 72%, возрастает на 15 - 26%.From the table it follows that with the introduction of the cooling process of the anolyte before filtering to 25 - 35 ° C and additional filtering of the working electrolyte, the yield of a suitable foil was 87 - 98.23%, i.e. in comparison with the prototype, where the yield of products is 72%, increases by 15-26%.
