Description
В насто щее врем антимонат натри перерабатываетс методом восстановительной плавки в электропечах.Currently, sodium antimonate is processed by the smelting reduction method in electric furnaces.
При такой плавке расход восстановител составл ет 15% от веса шихты, 1) ,мой выход извлекаемого .металла в черновую еурьму равен 80-85% и сурьма получаетс низкого качества с повьилеиным содержанием свинца. Дл осуи1ествлеии плавки требуютс значительные затраТЕЛ ручного труда.With this kind of melting, the consumption of the reducing agent is 15% of the weight of the charge, 1), my yield of recoverable metal in draft oil is 80-85% and antimony is obtained of poor quality with lead content. For the smelting of the smelting requires significant expenditure of manual labor.
Предлагаемый способ переработки аптимоната патрп позвол ет довести извлече1П)е сурьмы высокого качества до 99%, автонатпзироват и мехапизпроват, процеее, обеспечить концентраппю попутных металлов в кек н утилизировать содержащуюс в аитимонате окись патрп .The proposed method for the processing of the antimonate agent allows the extraction of high quality antimony to 99%, autoatatise and mechanically process, and ensure the concentration of associated metals in the waste material and utilize the oxide contained in the acidimonate.
Дл этого исходный антимонат натри выщелачивают при отношении Т : Ж - 1 : 20 и соотиошении сернистого натри в растворителе к сурьме в антимонате равным 2,2: 1.For this, the initial sodium antimonate is leached at a ratio of T: W - 1: 20 and the ratio of sodium sulphide in solvent to antimony in the antimonate is 2.2: 1.
Растворение антимоната натри в сернистом иатрии ведут прп 95- 98 н теченпе 2 час при механическом неремешивании. При этом 99,5- 99,8% сурьмы из антимоната переходит в раствор в виде окситносолей с образованием свободной щелочи. В цел х увелнчени экономичности нроцесса исиользуют сернпстр й натр отработанного электролита от гидромсталлургичеекой переработки сульфидного сурьм ного сырь .Dissolution of sodium antimonate in sulfurous and sodium lead to 95-98 n over 2 hours with mechanical non-mixing. At the same time, 99.5-99.8% antimony from the antimonate goes into solution in the form of oxy-salts with the formation of free alkali. In order to increase the efficiency of the process, the waste soda electrolyte sulphate from hydrostatic sulphide raw materials is used.
Из получе пк,чо раствора сурьму осаждают электролитическим способом в железпых ваппах с катодами из трехмиллпметровой листовой стали и аиодами из нолосовой стали при анодпой плотности тока 1000 a/.ii и температуре электролита 55-60°.From the PC, the solution of antimony is precipitated by electrolytic method in iron Wapps with cathodes of three millimeter sheet steel and aiodes of nolosovoy steel at anode current density of 1000 a / .ii and electrolyte temperature of 55-60 °.
Электролит еодержит (в г/л): 40-45 сурьмы, 50--60 сернистого натри н 45-50 едкого натри .The electrolyte contains (in g / l): 40-45 antimony, 50--60 sodium sulphide and 45-50 sodium hydroxide.
№ 132823 - 2 Получающийс отвальный по сурьме кек, в количестве 5-6% от веса антимоната натри , концентрирует свинец, индий, теллур и другие металлы.No. 132823-2 The resulting antimony-mold cake, in the amount of 5-6% by weight of sodium antimonate, concentrates lead, indium, tellurium and other metals.
Общее содержание нрнмесей в сурьме составл ет не более 0,1%. т. е. нолучаетс сурьма высокого качества.The total content of antimony in antimony is no more than 0.1%. i.e. high quality antimony is obtained.
Предмет изобретени Subject invention
Снособ переработки антимоната натри с регенерацией натронной составл ющей в едкий натр при производстве сурьмы, выщелачиванием сернистым натрием, отличающийс тем, что, с целью регенерации щелочи, исходный антимонат натри выщелачивают при откощении Т :Ж 1 :20 и соотнощении сернистого натри в растворителе к сурьме в антимонате равным 2,2: 1.A method of processing sodium antimonate with the regeneration of the soda constituent into caustic soda in the production of antimony, leaching with sodium sulphide, characterized in that, in order to regenerate alkali, the original sodium antimonate is leached at a concentration of T: G 1: 20, and the ratio of the sodium sulphate in the solvent is reduced in the solvent; in antimonate equal to 2.2: 1.
