Description
Корректировка рН реакционной среды водой существенно уменьшает возникновение очаговых зон с повышенным значением рН, что наблюдаетс при нейтрализации пульпы щелочным агентом, и повышает селективность осаждени гидроокиси марганца.Adjusting the pH of the reaction medium with water significantly reduces the occurrence of focal zones with an increased pH value, which is observed when the pulp is neutralized with an alkaline agent, and increases the selectivity of precipitating manganese hydroxide.
Пульпу осажденной гидроокиси марганца через буферную емкость непрерывно перекачивают на фильтрацию, причем величина расхода пульпы на фильтрацию автоматически согласовываетс с подачей раствора на очистку .The pulp of precipitated manganese hydroxide through the buffer tank is continuously pumped to the filtration, and the filtration flow rate of the pulp is automatically coordinated with the supply of the solution for cleaning.
ПрИменение описываемого способа позвол ет оптимизировать услови процесса и практически исключить соосаждение кобальта с гидроокисью марганца.The use of the described method allows to optimize the process conditions and practically exclude the co-precipitation of cobalt with manganese hydroxide.
Предмет изобретени Subject invention
Способ очистки кобальтовых растворов от ма рганца, включающий окисление марганцаThe method of purification of cobalt solutions from manganese, including the oxidation of manganese
газообразным хлором и осаждение его в виде гидроокиси при рН 1,0-1,8, отличающийс тем, что, с целью снижени содержани кобальта в гидроокиси .марганца, сокращени расхода реагентов и оптимизации условийgaseous chlorine and precipitating it as a hydroxide at a pH of 1.0-1.8, characterized in that, in order to reduce the cobalt content in the manganese hydroxide, reduce the consumption of reagents and optimize conditions
очистки кобальтового раствора от марганца рН подаваемого на очистку раствора довод т до 1,4-1,6, величину окислительно-восстановительного потенциала среды при окислении марганца поддерживают в пределах 1000-cleaning the cobalt solution from manganese, the pH of the solution supplied to the purification is adjusted to 1.4-1.6, the value of the redox potential of the medium during the oxidation of manganese is maintained within 1000-
1100 МБ относительно платинового и водородного электродов подачей газообразного хлора , а рН гидролиза марганца-добавлением воды.1100 MB relative to the platinum and hydrogen electrodes supplying chlorine gas, and the pH of the hydrolysis of manganese-the addition of water.
