Изобретение относитс  к Цветной металлургии .FIELD: non-ferrous metallurgy.

Известен способ рафинировани  цинка от железа алюминием. Выход рафинированного металла при этом достигает 88%.There is a known method for refining zinc from iron with aluminum. The yield of refined metal at the same time reaches 88%.

Предложенный способ отличаетс  тем, что расплав цинка покрывают карналлито-криолитовым флюсом, затем ввод т алюминий и рафинирование ведут при 550-600°С. Это позвол ет повысить выход рафинированного цинка до 97% и облегчить введение алюмини .The proposed method is characterized in that the zinc melt is coated with carnallite-cryolite flux, then aluminum is introduced and the refining is carried out at 550-600 ° C. This makes it possible to increase the yield of refined zinc up to 97% and facilitate the introduction of aluminum.

Сначала расплавл ют цинк, предназначенный дл  рафинировани , иод слоем защитного флюса. При температуре 600°С ввод т алюминий , расплав перемешивают, выдерживают 30-50 мин, затем снижают температуру до 550°С и отстаивают 30-50 мин. После выдержки очищенный eтaлл сливают в изложницы .First, zinc, intended for refining, is melted by iodine with a layer of protective flux. Aluminum is introduced at a temperature of 600 ° C, the melt is stirred, kept for 30-50 minutes, then the temperature is reduced to 550 ° C and settled for 30-50 minutes. After aging, the purified etal is poured into molds.

Пример. Дл  рафинировани  берут 2 кг цинка, содержащего 0,35% Fe. Металл расплавл ют при слоем флюса (95% карналлитаExample. For refining, 2 kg of zinc containing 0.35% of Fe is taken. The metal is melted with a layer of flux (95% carnallite

22

и 5% криолита), при температуре 600°С и расплав ввод т 12 г А1 так, чтобы отношение Al:Fe 2:l. Металл перемешивают в течение 3 мин и выдерживают при этой температуре, затем температуру снижают до 550°С и выдерживают еп1,е 40 мин. После этого металл выпускают через нижнее отверстие в тнгле. Содержание железа в рафпппрованном цннке составл ет 0,06%, выход металла - 96,2%. Предлагаемый способ повышает выход металла нрп рафнннровании до 95-97% н облегчает введение алюмини  в раснлав.and 5% cryolite), at a temperature of 600 ° C and the melt is introduced 12 g A1 so that the ratio Al: Fe 2: l. The metal is stirred for 3 minutes and kept at this temperature, then the temperature is lowered to 550 ° C and held for e1, e 40 minutes. After that, the metal is released through the lower hole in the pipe. The iron content in the raffinated grain is 0.06%, the metal yield is 96.2%. The proposed method improves the output of the metal of the NPA refining up to 95-97% n facilitates the introduction of aluminum into the raslav.

Предмет изобретени Subject invention

Способ рафинированн  цинка от железа алюминием, отличающийс  тем, что, с целью новьппени  выхода рафинированного металла и облегчени  введени  алюмини , раснлав цинка нокрывают карналлнто-криолитовым флюсом, затем ввод т алюминий и рафнннрованне ведут при 550-600°С.The method of refining zinc from iron with aluminum, characterized in that, in order to release refined metal and facilitate the introduction of aluminum, the zinc melt is covered with carnall cryolite flux, then aluminum is introduced and refined at 550-600 ° C.
