Изобретение относитс к металлурги платиновых металлов и. может быть использовано дл сорбционного концентрировани платиноидов из водных растворов .This invention relates to metallurgists of platinum metals and. can be used for sorption concentration of platinoids from aqueous solutions.
Известен способ извлечени платиновых металлов из раствора сорбцией оксигидратами металлов.A known method for extracting platinum metals from a solution by sorption of metals by oxyhydrates.
В известном способе осуществл етс извлечение платиновых металлов из гидратных или хлоридных растворов сорбцией гидроокисью железа. Сорбент насыщают металлами в статических услови х при комнатной температуре при рН 7-8 с последующим отделением осадка сорбента путем центрифугировани . Однако известный способ не позвол ет извлекать из водных растворов палладий и платину, т.е. не обеспечивает полного извлечени платиновых металлов из растворов.In a known method, the extraction of platinum metals from hydrated or chloride solutions by sorption with iron hydroxide is carried out. The sorbent is saturated with metals under static conditions at room temperature at pH 7-8, followed by separation of the sorbent precipitate by centrifugation. However, the known method does not allow the extraction of palladium and platinum from aqueous solutions, i.e. does not provide complete extraction of platinum metals from solutions.
Целью изобретени вл етс извлечение металлов.The aim of the invention is the extraction of metals.
Цель достигаетс тем, что сорбцию осуществл ют оксигидратами редкоземельных металлов при Т:Ж, равном И2 -102-1 -10.The goal is achieved by the fact that sorption is carried out by rare-earth metal oxyhydrates at T: W equal to I2-102-1 -10.
Сущность способа заключаетс в следующем. ..The essence of the method is as follows. ..
В качестве сорбентов примен ют порошкообразные окислы или смеси окислов (концентраты) редкоземельных металлов . Процесс ведут при температуре не выше точки кипени данного растврр ( преимущественно 60-80 С) при рН 5-9 и продолжительности процесса не менее 1 ч. Насыщенный сорбент отдел ют от раствора известными способами. Степень извлечени и скорость процесса возрастают при повьш ении температуры системы. .As sorbents, powdered oxides or mixtures of oxides (concentrates) of rare-earth metals are used. The process is carried out at a temperature not higher than the boiling point of this solution (preferably 60-80 ° C) at a pH of 5-9 and a process duration of at least 1 hour. The saturated sorbent is separated from the solution by known methods. The recovery rate and the process speed increase with increasing system temperature. .
Примеры использовани сорбентов оксигидратов редкоземельных метал-,Examples of the use of sorbents of rare earth metal oxyhydrates,
лов дл извлечени платиновых металлов и количественные результаты приведены в таблице.catalysts for the extraction of platinum metals and the quantitative results are shown in the table.
Как видно из приведенных данных, предложенным способом достигаетс высока степень извлечени платиноидов в характерных степен х окислени As can be seen from the above data, the proposed method achieves a high degree of extraction of platinoids in characteristic oxidation states.
//
из водньпс хлоридных и сульфатно-хлоридных растворов. В отличие от гидроокиси железа, сорбенты на основе окислов редкоземельных элементов с больщей полнотой извлекают не только рутений, осмий, родий, но и платину (IV), палладий (11) и, в особенности платину (II). Извлекаетс также трудноизвлекаемый иридий (III, IV). Значени предельной сорбции достигают значительных величин: 6 мае. % паллади ; 35 мае. % платины (II). Степень извлечени платиноидов в случа х, когда предельные значени сорбции не достигаютс , равны или близки к 100% Наилучщие результаты получают дл оксигидратных сорбентов на основе иттри (III), самари (III)и иттрийиттербиевых концентратов при температурах , близких к , и соотношени х Т;Ж, предусматривающих дев ностопроцентное использование емкости сорбентов.from water chloride and sulphate-chloride solutions. Unlike iron hydroxide, sorbents based on oxides of rare-earth elements with greater completeness extract not only ruthenium, osmium, rhodium, but also platinum (IV), palladium (11) and, in particular, platinum (II). Hard to recover iridium (III, IV) is also recovered. The values of the limiting sorption reach significant values: 6 May. % palladium; May 35 % platinum (II). The degree of extraction of platinoids in cases where the limiting values of sorption are not reached, equal to or close to 100%. The best results are obtained for oxyhydrate sorbents based on yttrium (III), samarium (III) and yttrium titanium concentrates at temperatures close to and ratios T ; G, providing for devostocent use of the capacity of sorbents.
Предлагаемые сорбенты универсальны; сорбции разных платиноидов и платиноидов в различных степен х окислени , например платины (II) и платины (IV), независимы друг от друга, что обеспечивает весьма полное извлечение всех платиноидов из водных сульфатно-хлоридных растворов и получение концентратов с более высоким содержанием целевого продукта, чем в случае органических сорбентов и гидроокиси железа.Sorbents offered are universal; sorption of different platinoids and platinoids in different degrees of oxidation, such as platinum (II) and platinum (IV), are independent of each other, which ensures a very complete extraction of all platinoids from aqueous sulfate-chloride solutions and the production of concentrates with a higher content of the target product, than in the case of organic sorbents and iron hydroxide.
