Изобретение относитс  к области цветной металлургии, а именно, к гидрометаллургическим способам извлечени  селена и теллура из отходов медеэлектролитных заводов.The invention relates to the field of non-ferrous metallurgy, namely, to hydrometallurgical methods for extracting selenium and tellurium from wastes of copper electrolyte plants.

Известен способ извлечени  селена и теллура выщелачиванием в сернокислой среде с добавкой хлор-иона.A known method for the extraction of selenium and tellurium by leaching in sulfuric acid with the addition of chlorine ion.

Цель изобретени  - повысить степень извлечени  металлов. Это достигаетс  тем, что выщелачивание осуществл ют в присутствии анионообменной слюлы в количестве 10-20% от веса сухого продукта.The purpose of the invention is to increase the degree of metal recovery. This is achieved in that the leaching is carried out in the presence of anion exchange saliva in an amount of 10-20% by weight of the dry product.

Пример. В агитатор загружают пыль отражательной плавки медеэлектролитных шламов , содержащих селен и теллур, в количествеExample. The agitator is loaded with dust of the reflective melting of copper electrolyte slimes containing selenium and tellurium, in the amount of

100 г. Выщелачивание осуществл ют серной кислотой 150 г/л при в присутствии 10% бертолетовой соли и ионита АВ-17 в количестве 10% от твердого. Процесс ведут при 50-70°С в течение 3 час. В раствор переходит селена 87%, теллура 46%.100 g. Leaching was carried out with sulfuric acid 150 g / l with in the presence of 10% bertolet salt and AB-17 ion exchanger in the amount of 10% of the solid. The process is conducted at 50-70 ° C for 3 hours. In the solution passes selenium 87%, tellurium 46%.

Предмет изобретени Subject invention

Способ извлечени  селена и теллура выщелачиванием в сернокислой среде с добавкой хлор-иона, отличающийс  тем, что, с целью повышени  степени извлечени  металлов в раствор , выщелачивание осуществл ют в присутствии анионообменной смолы в количестве 10-20% от веса с хого продукта.The method of extracting selenium and tellurium by leaching in sulfuric acid with the addition of chlorine ion, characterized in that, in order to increase the degree of metal extraction into the solution, leaching is carried out in the presence of an anion exchange resin in an amount of 10-20% by weight of the chemical product.
