Description
Изобретение относитс к технологии полчени солей марганца, используемых дл приготовлени электролитов, из которых электролизом выдел ют металлический марганец и его двуокись.The invention relates to the technology for the production of manganese salts used to prepare electrolytes, from which manganese metal and its dioxide are separated by electrolysis.
Известньй способ получени растворов солей марганца путем обработки кусков марганцевой руды и ферромарганца соотвегствующей кислотой, обладает ведостаткамв , к которым относ тс длительностьThe limestone method of obtaining solutions of manganese salts by treating pieces of manganese ore and ferromanganese with the corresponding acid has a major effect, which is the duration
прсщесса растворени марганца в каслоте, невыссжа степень извлечени его из исходных продуктов, взрывоопасность прсадесс за счет выделени значительного колн ест ва водорода при растворении ферромарганца в кислом растворе.the process of dissolving manganese in caslottes, the degree of its extraction from the initial products, the explosivity of the process due to the release of a significant amount of hydrogen by dissolving the ferromanganese in an acidic solution.
С целью устранени указанных ведостатксв предлагаетс куски марганцевой руды и ферромарганца, крупность которых в 2-5 раз больше крупности кусков руды,In order to eliminate these vedostatksv offers pieces of manganese ore and ferromanganese, the size of which is 2-5 times the size of the ore,
предварительно совместно измельчать в водной среде до крупности кусков менее 250 меш, затем обрабатывать соогветствуюшей кислотсй, количество которой на 1-10% меньше стехиометрического, а дл pre-co-grind in an aqueous medium to a lump size of less than 250 mesh, then process the corresponding acid, the amount of which is 1-10% less than stoichiometric, and for
св зывани ионов кальци , содержащихс в исходных компонентах, добавл ть серную кислоту в количестве 100-300% от необходимого по,стехиометрии. Чтобы исключить присутствие в растворе солей двухвалентного железа, выделение водорода в газовую фазу и наличие в шламе металлического марганца, в смесь подают на 1-30% меньше ферромарганца, чем необходимо по реакции Мп Мп 2 ЛЦ,the binding of calcium ions contained in the starting components, add sulfuric acid in the amount of 100-300% of the required, stoichiometry. In order to exclude the presence of ferrous iron salts in the solution, hydrogen evolution into the gas phase and the presence of metallic manganese in the sludge, 1-30% less ferromanganese is fed into the mixture than is necessary by the reaction Mn Mn 2 LC,
По предлагаемс лу способу получени растворов солей марганца, не содержашнх вредных примесей ион(ж железа и кальци , происходит за 15-ЗО мин практвчес к без выделени водорода. Извлечение марг ца ИЗ исходного сырь 9О-Э8%.According to the proposed method of obtaining solutions of manganese salts, no ion-containing harmful impurities (iron and calcium, occurs in 15-ZO mines practically without hydrogen evolution. Extraction of minerals FROM the raw material 9O-E8%.
