Abstract

Изобретение относитс  к гидрометаллургии цветных металлов, в частности к переработке сурьмусодержащих материалов. Цель изобретени  - повышение производительности процесса. Сурьмусодержащие материалы выщелачивают сульфидно-щелочным раствором, раствор обрабатывают материалом, содержащим металлическую сурьму, в автоклавных услови х при 120-130°С в течение 15-20 мин при стехиометрическом расходе металлической сурьмы на восстановление тиосульфата натри , после чего провод т электролиз сурьмы. 1 табл.This invention relates to hydrometallurgy of non-ferrous metals, in particular to the processing of antimony-containing materials. The purpose of the invention is to increase the productivity of the process. Antimony-containing materials are leached with a sulphide-alkaline solution, the solution is treated with a material containing metallic antimony under autoclave conditions at 120-130 ° C for 15-20 minutes at a stoichiometric consumption of metallic antimony to reduce sodium thiosulfate, and then electrolysis is carried out. 1 tab.

Description

Изобретение относитс  к гидрометаллургии цветных металлов, в частности к переработке сурьмусодержащих материалов.This invention relates to hydrometallurgy of non-ferrous metals, in particular to the processing of antimony-containing materials.

Цель изобретени  - повышение производительности процесса.The purpose of the invention is to increase the productivity of the process.

Изобретение иллюстрируетс  следующими примерами.The invention is illustrated by the following examples.

Пример. Обрабатывали в автоклаве СШР сурьмы состава, Sb 6А,8; ,03 9,1; Na,S 7,5; Na.CO, 14,5; ,2, Hg i,i.Example. Treated in an autoclave SSR antimony composition, Sb 6A, 8; , 03 9.1; Na, S 7.5; Na.CO. 14.5; , 2, Hg i, i.

Продолжительность обработки варьировали от 5 до 60 мин, расход металлической сурьмы от 100% до 500 от теоретического. Температурный режим измен ли в пределах от 100 до 1бО°С, содержание гидроксида в растворе от 5 до 40 г/дмз.The processing time varied from 5 to 60 minutes, the consumption of metal antimony from 100% to 500 from the theoretical. The temperature regime varied from 100 to 1bO ° C, the hydroxide content in the solution was from 5 to 40 g / dmz.

Скорость восстановлени  тиосульфата натри  в автоклаве в оптимальных услови х составила 0,62-0,82 г/ /дмз. мин, что в 7-9 раз выше скорости в известном способе.The rate of reduction of sodium thiosulfate in an autoclave under optimal conditions was 0.62-0.82 g / dmz. min, which is 7-9 times higher than the speed in a known way.

Растворы после восстановлени  в автоклаве подвергались электролизу в услови х, близких к промышленным. Результаты представлены в таблице Как следует из представленных в таблице результатов, предложенный способ позвол ет повысить выход сурьмы по току, что приводит к повышению производительности процесса гидрометаллургического получени  сурьмы на .The solutions, after reduction in an autoclave, were subjected to electrolysis under conditions close to industrial ones. The results are presented in the table. As follows from the results presented in the table, the proposed method makes it possible to increase the current yield of antimony, which leads to an increase in the productivity of the process of hydrometallurgical production of antimony.
