第一節 淨液的目的在電解操作过程中,陽極粗銅中的許多雜質溶解於電解液內,由於電解液中雜質逐漸增加,游離硫酸漸次降低,同時電解放電阻亦相应增加,使電解槽槽電压上升,結果提高了單位重量電銅的電力消耗;最嚴重地是增大了与銅電位相接近的金屬(如As、Sb、Bi等)雜質在陰極上析出的机会,使電銅質量低劣,達不到電解精煉的預期效果。為了使電解操 Purposes of the first section of the net In the electrolysis process, many impurities in the anode blister dissolved in the electrolyte, the electrolyte gradually increased due to impurities gradually reduce the free sulfuric acid, while the resistance of the discharge also increased accordingly, the electrolytic tank slot As a result, the power consumption per unit weight of the copper increases, and the most serious problem is that the chance of precipitation of impurities such as As, Sb, Bi and the like close to the copper potential on the cathode increases, Poor, can not reach the expected effect of electrolytic refining. In order to make electrolysis
