This article describes a new process for the continuous decopperization of crude lead, which has been applied in the Shenyang Smelter since September 1974. The basic principle of the process and the structure of the furnace are described. The production practice, operational experience, principal technical indices and process improvements in the past five years are given in detail. The article further describes the following new propositions about the process. (1) There is no relationship between the copper content in decoppered lead and the lead content in the matte produced. Even when the Cu content in the decoppered lead is less than 0.08%, high Cu: Pb ratio matte can be produced. (2) The ratio be- tween sulfur and copper (S/Cu) in the charge should be 0.5 instead of 0.25. A ratio of 0.25 is not sufficient for the process. (3) In order to decrease the lead content in the matte and to raise the Cu: Pb ratio, it is necessary and reasonable to add some scrap iron to replace the lead in it. To judge the correct end point of iron addition is the crux of the process. The composition of the crude lead treated is as follows (%): 96-97.5 Pb, 0.8- 1.3 Cu, 0.3 As, 0.8 Sb and 0.2-0.5 S. The blast-furnace crude lead is charged into the furnace as hot liquid. Then 0.6-0.8% soda, 0.2-0.3% coke and 2% lead sulfide con- centrate are added. The decoppered lead is discharged from the end of furnace by syphoning. De- pending on the degree of aggregation, the matte and slag are discharged about once a day. After discharging the slag, scrap iron is added into the matte to replace the lead in it. The Cu content of the output lead is 0.05-0.08%, it may be cast into anodes directly for e1ectrolysis. Lead content of the tapped slag is<2%. The matte has a Cu: Pb ratio of 3-5 (average 4), and can be sent to the copper smelter to re- cover copper without additional treatment. The productivity of the furnace bed is 10-l2 t/m~2. day. The decopperization efficiency is about 95%. In the output lead the recovery of Pb is about 99%, Sb-80%, As-70%. The volatility of lead is 0.3-0.4%. Finally, it is pointed out that maintaining a S: Cu ratio of 0.5 is of importance to the decopperization and matte formation process and in the elimination of bloc- kage.

本文简要地叙述了沈阳冶炼厂的粗铅连续脱铜新工艺。文中就脱铜过程阐述了如下一些新的论点:脱铜铅含铜与产出的冰铜含铅(或铜铅比)无关。在脱铜铅含铜低于0.08%的同时,能够产出钢铅比较高的冰铜;炉料中的硫铜比应保持0.5,而不是0.25;为了降低冰铜含铅,提高铜铅比,向冰铜中加入铁屑置换其中的铅是必要的,合理的,准确地判断加铁过程的终点是这一操作过程的关键。

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...

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。
