(5) СПОСОБ ИЗВЛЕЧЕНИЯ БЛАГОРОДНЫХ МЕТАЛЛОВ ИЗ МЕДЕЭЛЕКТРОЛИТНЫХ ШЛАМ08 (5) METHOD FOR EXTRACTING NOBLE METALS FROM MEDICAL ELECTROLYTIC SLAM08
1one
Изобретение относитс к металлургии благородных металлов, а именно к. способам переработки медеэлектролитных шламов.The invention relates to the metallurgy of noble metals, namely to methods for processing copper electrolyte sludges.
Известен способ извлечени бпагородных металлов из медного шлама плавкой шихты с получением золотосеребр ного сплава, шлака и пыли til.A known method for extracting base metals from copper sludge by melting the mixture to produce a gold-silver alloy, slag and dust til.
Наиболее близким по технической сущности и достигаемому результату к предлагаемому вл етс способ извлечени благородных металлов из медеэлектролитных шламов плавкой ripH 1200-1300С с получением золото-се- ребр ного сплава, шлака и пыли 2. The closest in technical essence and the achieved result to the proposed method is the method of extracting precious metals from copper electrolyte sludge by melting ripH 1200-1300С with obtaining gold-silver alloy, slag and dust 2.
Недостаток указанного способа невысока степень извлечени благородных металлов.The disadvantage of this method is the low degree of extraction of precious metals.
Эта цель достигаетс тем, что в способе извлечени благородных металлов из медеэлектролитных шламов , плавкой при 1200-1300°С с получение золото-серебр ного сплава, шлака иThis goal is achieved by the fact that in the method of extracting precious metals from copper electrolyte slimes, melting at 1200–1300 ° С with obtaining a gold – silver alloy, slag and
ПЫЛИ, перёд плавкой провод т обработку шламов органическим восстановителем в количестве 100-500% от теоретически необходимого.А в качестве органического растворител используют спирт и глицерин.DUST, fusible, the sludge is treated with an organic reducing agent in the amount of 100-500% of the theoretically necessary. Alcohol and glycerin are used as the organic solvent.
Сущность способа заключаетс в том, что шихту обожженных шламовThe essence of the method lies in the fact that the mixture of baked sludge
