Description
(54) СПОСОБ ОКИСЛИТЕЛЬНОГО АВТОКЛАВНОГО ВЫШЕЛАЧИВАНИЯ СУЛЬФИДОВ ЦВЕТНЫХ МЕТАЛЛОВ(54) METHOD OF OXIDATIVE AUTOCLAVE LEISHER SULFIDE OF NON-FERROUS METALS
Изобретение относитс к цветной металлургии , в частности к гидрометаллургичес ким способам переработки сульфидных матер риалов, содержащих цветные металлы.The invention relates to non-ferrous metallurgy, in particular to hydrometallurgical methods for processing sulphide materials containing non-ferrous metals.
Известен способ окислительного автоклавного вьпцелаЧИВани сульфидов цветных металлов при избыточном: давлении и температуре , превышающей температуру плавлени серы, в присутствии поверхностно-активного вещества, например, класса полисахаридов попученнем элементарнойThe known method of oxidative autoclaving of cellation of non-ferrous metal sulphides with excess: pressure and temperature exceeding the melting point of sulfur in the presence of a surfactant, for example, a class of polysaccharides
Способ недостаточно интенсивен и не позвол ет достаточно полнс( разложит, сульфиды .The method is not intensive enough and does not allow sufficiently full (decomposed, sulphides.
Цель изобретени - устранение BwmejrKaзанных недостатков.The purpose of the invention is the elimination of BwmejrKazannyh disadvantages.
Это достигаетс тем, что в качестве пойерхностно-активного реагента -ие испопьауетс вещество группы циатимов, например циатгм - 2О8.This is achieved by using the substance of the group of cyatimes as a surfactant reagent, for example cyatgm — 2O8.
Процесс выщелачивани ведут при температуре 12О-250- С, преимущественно при 13О-16О°О и парциальном давлении кислорода в пределах 5-ЗО атм, преимущественно при 5-15 атм.The leaching process is carried out at a temperature of 12 ° -25 ° C, preferably at 13 ° -16 ° C and at a partial pressure of oxygen within 5 to 30 atm, preferably at 5-15 atm.
Поверхностно-активный реагент ввод т в пульпу перед выщелачиванием.The surfactant is introduced into the slurry before leaching.
Пример 1, Опыт с галогеном ионот-1Example 1, Experience with halogen ionot-1
Выщелачивание пирротинсодержашего концентрата производили в автоклаве емкостью 3 м В автоклав загружали 2,5 дм пульпы исхок- него концентрата. Внутренн поверхность автоклава футерована коррозионностойкой эмалью. Опыт проводилс при температуре 140 С, парциальном давлении кислорода 8 атм.Leaching of the pyrrhotite-containing concentrate was carried out in an autoclave with a capacity of 3 m. 2.5 dm of pulp from the concentrate was loaded into the autoclave. The inner surface of the autoclave is lined with corrosion-resistant enamel. The experiment was conducted at a temperature of 140 ° C and a partial pressure of oxygen of 8 atm.
В исходную пульпу концентрата дл вы щелачивани задавалась серна кислота ЕЗ расчета 15О г/л хлористый натрий в коли честве 1% от веса твердого. Пульпу нагре« вали в автоклаве до требуемой теьтературы5 после чего включали перемешшзающее устройство и подавали в аьтоклав кислород, ., Начало опыта считалось с момента) цоцачи в автоклав, кислорода. Через заданное врем после начала опыта пульпа в автоклаве охлаждалась. Фильтрацией отдел ли твердый продукт от раствора. Продукты вытепачтSulfuric acid E3 was calculated for the alkalization of the initial concentrate pulp in the calculation of 15O g / l of sodium chloride in the amount of 1% by weight of the solid. The pulp was heated in an autoclave to the required temperature5, after which the mixing device was turned on and oxygen was supplied to the autoclave,. The beginning of the experiment was counted from the moment when the autoclave was charged to oxygen. After a specified time after the start of the experiment, the pulp in the autoclave was cooled. The solid was separated from the solution by filtration. Products vytepchat
