亜鉛を含むからみから亜鉛を回収する方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for recovering zinc from zinc-containing tangles, mainly tangles generated from lead blast furnaces, using a slag fuming method. This invention relates to a method for recovering zinc from entanglements containing zinc, which makes it possible to improve the decomposition rate of zinc by adding spices together with entanglements.

ていた。Conventionally, the slag fuming method has been carried out to recover zinc from zinc-containing slag, mainly tangles generated from lead blast furnaces. They relied on adding carbon sources such as coke.
然し乍ら、鉛溶鉱炉から発生したからみには亜鉛が酸化
亜鉛の他に硫化亜鉛の形で存在するため、炭素源を利用

亜鉛骨を回収出来ず、結果的に全体としての亜鉛分離率
を低くしていた。However, since zinc is present in the form of zinc sulfide as well as zinc oxide in the slag generated from lead blast furnaces, if the reduction treatment is limited to using carbon sources, the amount of zinc sulfide will be reduced. could not be recovered, resulting in a low overall zinc separation rate.

鉛の還元をも進め、結果的にからみからの亜鉛分離率を
大幅に増大させる方法を提供するものである。The present invention is a slag fuming method for reducing zinc-containing tangles generated in non-ferrous smelting. By adding spices as the main ingredient, in addition to the zinc that was conventionally obtained through reduction and separation using only a carbon source, the reduction of zinc sulfide using the reducing ability of metallic iron was promoted, resulting in the reduction of zinc sulfide. The present invention provides a method for significantly increasing the rate of zinc separation from grains.
ここにスラグヒューミング法とは、密閉式電気炉に溶融
状態の鉛溶錬からみを装入し、加熱還元して亜鉛を揮発
させるもので、亜鉛はスプラッシュコンデンサーで蒸溜
亜鉛として回収される。The slag fuming method is a method in which molten lead is charged into a closed electric furnace and heated and reduced to volatilize the zinc, which is then recovered as distilled zinc in a splash condenser.
又、スパイスとは、砒ひとも呼ばれるものであり、融体
では均一に溶けあっている重金属砒化物である。鉛製錬
では後処理が面倒になるためスパイスの生成は好まれな
いが、原料中に砒素やアンチモンが相当量含まれるよう
な場合、金属鉛を得るために還元性雰囲気で操業すると
、原料中に含まれる銅や鉄も還元をうけ、過剰に存在す
る砒素やアンチモンと合金を作りスパイスとなる。Spice is also called arsenide, and is a heavy metal arsenide that is uniformly dissolved in the melt. The production of spices is not preferred in lead smelting because post-treatment is troublesome, but if the raw materials contain a considerable amount of arsenic or antimony, operating in a reducing atmosphere to obtain metallic lead will cause the production of spices in the raw materials. The copper and iron contained in it are also reduced and form an alloy with the excess arsenic and antimony, forming a spice.
スパイスはマントよりもより金属的性質が強いものであ
る。Spices are more metallic than cloaks.
スパイスの添加量を多くする事は、発生して来る砒素の
処理と未反応のままで残存するスパイスの処理に別の問
題を提供する事になる為好ましい事ではなく、この面か
ら、重量比でからみ中の亜鉛骨が５〜１０％と云う通常
操業状態では、からみに対するスパイスの添加量が５重
量％を超える事はあまり好ましい事ではない。Increasing the amount of spice added is not desirable because it presents another problem in processing the arsenic that is generated and the remaining unreacted spice, and from this point of view, the weight ratio Under normal operating conditions, where the zinc bone content in the entanglement is 5 to 10%, it is not very desirable for the amount of spice added to the entanglement to exceed 5% by weight.

らみから分離された事が確認された。Using an alumina crucible in a siliconite electric furnace under a nitrogen gas atmosphere, it was melted at 1300℃ with 2 kg of slag generated from the blast furnace in the simultaneous lead and zinc smelting method called the ISP method and spice loog coexisting. After confirming that the charge was in a molten state, air was pumped into the molten metal from the outside at a rate of 217 Ilin using an alumina hollow tube with an inner diameter of 5 W, and at the same time, 4.7 g/g of powdered coke was pumped into the molten metal.
The molten metal was blown into the molten metal together with air at a rate of 1,300° C., and the stirring operation of the molten metal was continued for 1 hour while maintaining the molten metal temperature at 1300°C. When the heating was stopped after the stirring operation was completed and a composition analysis was attempted on the charge that had been cooled to room temperature, it was found that:
The zinc content in the charge before treatment according to the present invention was 7% by weight, but the zinc content decreased to 2.0% by weight after treatment. It was confirmed that more than 70% of the content was separated from the initially charged tangle.
又、同時に行なった鉛の含有率分析によると、実に９６
