Description
Изобретение относитс к области цветной металлургии, в частности, к способам переработки отвальных продуктов сурьм ного производства .The invention relates to the field of non-ferrous metallurgy, in particular, to methods of processing dumped products of antimony production.
Известен способ переработки отвальных продуктов сурьм ного .производства, включающий обжиг исходных материалов с последующей восстановительной плавкой возгонов обжига .There is a method of processing dumped products of antimony production, including the firing of raw materials with the subsequent reduction melting of sublimates of roasting.
Предложенный способ отличаетс тем, что в качестве исходного сырь иснользуют кеки гидрометаллургического сурьм ного производства , обжнг ведут при 900-1000°С с 30% коксика , полученные возгоны подвергают восстановительной плавке при 950-1150°С с 15% коксовой пыли, что позвол ет получать товарную свинцовистую сурьму.The proposed method is different in that the hydrometallurgical antimony production cakes are used as feedstock, baking is carried out at 900-1000 ° С with 30% coke, the sublimates obtained are subjected to reduction melting at 950-1150 ° С with 15% coke dust, which allows receive marketable lead antimony.
Кеки, отвальный продукт сульфидно-щелочного выщелачивани сульфидных сурьм ных коицентратов и антимоната натри , нодвергают дистилл ционному обжигу с 30% коксмка при 900-1000°С. При этих услови х процесса степень возгонки соединеннй сурьмы и свннца составл ет 92-97%. Возгоны улавливают в системе пылеулавливани . Пыль с содержанием 5-10% сурьмы вл етс оборотной. Возгоны с содержанием 30-40% сурьмы и 16-27% свинца наиравл ют на восстановительную содовую нлавку. Плавку ведут при 1150°С с добавлением в шнхту 15% коксика и 40% кальцинированной соды от веса возгонов.Keki, the waste product of sulfide-alkaline leaching of sulfide antimony concentrates and sodium antimonate, is subjected to distillation roasting with 30% coke at 900-1000 ° C. Under these process conditions, the degree of sublimation of the combined antimony and starter is 92-97%. Sublimates are caught in the dust collection system. Dust containing 5-10% antimony is recyclable. Sublimates with a content of 30–40% antimony and 16–27% lead lead to reducing soda water. Melting is carried out at 1150 ° C with the addition of 15% coke into the shnhta and 40% soda ash by weight of sublimates.
В результате нлавки получают три продукта: сурм но-свинцовый сплав, отвальный шлак и возгоны системы пылеулавливани .As a result, three products are obtained: alum-lead-alloy, waste slag and sublimates of the dust collection system.
Сурьм но-свинцовый оплав, полученный этим способом, может быть использован дл получени любых свинцово-сурм ных сплавов.The antimony-lead alloy obtained by this method can be used to produce any lead-surmide alloys.

Способ переработки отвальных продукто15 сурьм ного производства, включающий обжиг исходных материалов с последующей восстановительной планкой возгонов обжига, отличающийс те.м, чго, с целью получени свипцовистой сурьмы, в качестве исходного сырь используют кеки гндрометаллургического сурьм ного производства, обжиг ведут ири 900-1000°С в 30% коксика, полученные возгоны подвергают восстановительиой плавке при 950-1150°С в 15% коксовой пыли.The method of processing dumped products of antimony production, including firing of raw materials with subsequent reduction bar for roasting sublimates, differing from m With 30% of coke, the obtained sublimates are subjected to reducing smelting at 950-1150 ° C in 15% coke dust.
