Originally, the fundamental relationship between gas composition and current efficiency (CE) was based on the assumption that the primary anode reaction is evolution of CO_2, and that the loss in CE is due to reoxidation of the metal by CO_2. In order to account for the possible side reaction between CO_2 and C, and for the loss in CE not reflected in the gas composition a new equation was derived, which is γ= (1 + CO_2%)(1 + x)/2 = γ2 The values of x and γ2 were evaluated based on long-term measurements on...

Originally, the fundamental relationship between gas composition and current efficiency (CE) was based on the assumption that the primary anode reaction is evolution of CO_2, and that the loss in CE is due to reoxidation of the metal by CO_2. In order to account for the possible side reaction between CO_2 and C, and for the loss in CE not reflected in the gas composition a new equation was derived, which is γ= (1 + CO_2%)(1 + x)/2 = γ2 The values of x and γ2 were evaluated based on long-term measurements on indu- strial aluminum electrolysis cells. In addition, characteristic curvest showing the variations of CO_2 concentration in the anode gas during normal electrolysis as well as before and after the anode effect, were carefully studied. Correlations between the flame colour of the cell gas and CE are also reported.

气体成分与电流效率的关系,原先是根据阳极一次反应是析出CO_2,而电流效率损失是由于金属被CO_2氧化的理论。现在为了兼顾CO_2与C之间的副反应以及没有反映在气体成分中的那部分电流效率损失,推导得一个新的式子:γ=(1+CO_2%)(1+X)/2-γ_2。根据对工业电解槽的长期测定结果,估算了x值和γ_2值。并研究了正常电解过程中和阳极效应前后的CO_2浓度变化特征曲线。报道了槽上气体燃烧时的火苗颜色与电流效率的对比关系。

This paper describes the problem of recovery and utilization of oxygen-rich cellgas obtained from electrolytic zinc cells, which has never been used as a valuable resource of oxygen. This cell-gas is a mixture containing a large amount of oxygen formed at the anode and a small amount of hydrogen formed at the cathode. The O_2 to H_2 ratio is dependent upon the mode of enclosure of the electrolysis cell and the technical conditions such as current density, current efficiency etc. In this investigation a...

This paper describes the problem of recovery and utilization of oxygen-rich cellgas obtained from electrolytic zinc cells, which has never been used as a valuable resource of oxygen. This cell-gas is a mixture containing a large amount of oxygen formed at the anode and a small amount of hydrogen formed at the cathode. The O_2 to H_2 ratio is dependent upon the mode of enclosure of the electrolysis cell and the technical conditions such as current density, current efficiency etc. In this investigation a simple recovery method using a semi-enclosed type cell has been developed, by which a cell-gas containing 25-35% oxygen and 1-4% hydrogen can be obtained. The cell-gas can be used in oxygen-enriched smelting of nonferrous metals or other combustion processes. Other benefits are the elimination of acid mist pollution during electrowinning of zinc and an increase in metal recovery.

本文论述了硫酸锌溶液电积过程中产生的富氧槽气的回收和利用问题。这是一项至今尚未被综合开发的、有潜在价值的氧源。槽气是一种氧含量大、氢含量少的混合气体。槽气中氢氧比取决于电解槽的密闭程度和电积技术条件,如电流密度、电流效率等。文中提出的“半封闭式简易槽面下抽吸捕气法”,通过用空气稀释的方法可以得到含氢远低于“氢爆”极限以下,完全可作为有色冶炼所需的富氧气体。

The state of arsenic and antimony in the copper electrolyte during refining is analysed with the help of potential -pH diagrams for the As-H_2O and Sb-H_2O systems. It shows that more than 95% of the As (Ⅴ) is in the form of undissociative H_3AsO_4, less than 5% As (Ⅲ) is mainly in the form of AsO+ and HAsO_2 while the concentration of the former is about double of the latter. The amount of Sb(Ⅴ) in the electrolyte is more than that of Sb(Ⅲ). The Sb (Ⅴ) is mainly in the form of SbO_3~- and SbO_2~+,the former...

The state of arsenic and antimony in the copper electrolyte during refining is analysed with the help of potential -pH diagrams for the As-H_2O and Sb-H_2O systems. It shows that more than 95% of the As (Ⅴ) is in the form of undissociative H_3AsO_4, less than 5% As (Ⅲ) is mainly in the form of AsO+ and HAsO_2 while the concentration of the former is about double of the latter. The amount of Sb(Ⅴ) in the electrolyte is more than that of Sb(Ⅲ). The Sb (Ⅴ) is mainly in the form of SbO_3~- and SbO_2~+,the former is about four to five times more than the latter. The Sb (Ⅲ) is mainly in the form of SbO+ and HSbO_2, while the SbO+ content is about thirty times more than that of HSbO_2. The As (Ⅴ) and Sb (Ⅴ) might be reduced to As (Ⅲ) and Sb (Ⅲ) during electrolysis, because their reduction potentials are higher than that of copper. Since the reduction potentials of As (Ⅲ) and Sb (Ⅲ) are more negative than that of Cu, it is possible to prevent the deposition of arsenic and antimony on the cathode by keeping the mass transfer of Cu~(2+) in good condition and confining cathodic current density. In order to refine the crude copper with high arsenic and antimony content by electrolysis, we have developed a new method to remove successfully the arsenic from the electrolyte, i.e. the reduction with sulphur dioxide. With this method the rate of arsenic removal in the electrolyte can be improved from the current 30% to 90%. Besides, the sulphur dioxide reduction method can also be used in many other fields.

本文用As—H_2O系、Sb—H_2O系电位—pH图分析了砷锑在高砷锑铜电解液中存在的形态。电解液中的As(V)、Sb(V)因其电位较铜正,将被还原成As(Ⅲ)和Sb(Ⅲ);而由As(Ⅲ),Sb(Ⅲ)还原为As、Sb的电位比铜负,故只要电解液中的Cu~(2+)具有良好的传质条件,并限制阴极电流密度,As、Sb就不会在阴极上和铜共同析出。为适应高砷锑铜料电解精炼的需要,我们还研究成功了一种电解液脱砷的新方法——SO_2还原法,可使电解净液的脱砷率从传统方法的30%提高至90%以上。
