一、前言当熔化阳极锌时,由于锌容易氧化,因此产生浮渣,渣量为熔化阳极锌的4～10％。渣量主要是取决于阳极锌质量的好坏和在熔化炉中浮渣与氯化铵搅拌的程度。浮渣是由金属锌与氧化锌组成的,金属锌含量为浮渣量的50％以上。因浮渣内含有大量锌(90.47％),所以必须采用有效的办法,进行回收,首先将渣内金属锌提取出来,然后对提出金属锌后的残渣,再用合理的办法,进行处理,这祥才能得到较高的金属回收率,不致造成浪费。我们为了配合设计工作及生产上的需要,根据苏联专家建议,进行了试验室小型试验。二、浮渣处理的方法目前我厂对浮渣处理,还没有
I. INTRODUCTION When melting anodic zinc, scum is generated due to zinc being easily oxidized, and the amount of slag is 4 to 10% of the molten anodic zinc. The amount of slag is mainly dependent on the quality of the anode zinc and the degree of scum mixing with ammonium chloride in the melting furnace. Scum is composed of metallic zinc and zinc oxide, metallic zinc content of more than 50% of the amount of scum. Because scum contains a large amount of zinc (90.47%), it must be an effective way for recycling, first of all, the extraction of metal zinc inside the slag, and then put forward the residue after the metal zinc, and then a reasonable approach to deal with this Cheung can get a higher metal recovery, will not result in waste. In order to meet the needs of design work and production, we conducted small-scale laboratory tests according to the advice of Soviet experts. Second, the method of scum treatment At present, I plant treatment of scum, not yet
