Description

Изобретение относитс  к гй врометаллурги  т желых Еэе-rHbiS металиое.This invention relates to heavy metals and heavy Eee-rHbiS metals.

Известен способ переработки cy a ф5iйныx руд и концентратов аьгинглачйванкем TOfiKO- измельченного материала хлорсодержащкм раствором в присутствии К1€слорода.There is a known method of processing cyaf5iynyh ores and concentrates of inginglachivankem TOfiKO- crushed material with a chlorine-containing solution in the presence of K1 € of hydrogen.

Цепь изобретени  повысить извлечение металлов.The inventive chain enhances metal recovery.

Предлагают выщелачиванке вести а присутствии двуокиси серы растаорэм, содер- жащим 3,6 моль кйСлоты и 0,9 мол пвуокпс  серы при 150-250.A leach is suggested to be carried out in the presence of sulfur dioxide, a rastaorem containing 3.6 mol of kSlota and 0.9 mol of sulfur pvocox at 150-250.

Способ пригоден длк вь иелачиванй  сулоь, фидпых руд, содержащих например халькопирит , галенит, пеитландит железный 5со че- дан.The method is suitable for treating sediments, feed ores containing, for example, chalcopyrite, galena, iron peitlandite 5th grade.
