Abstract

This study explores the recovery and preparation of Pb from Zn plant residues (ZPR), specifically leaching filter cake (LFC), through a hydrometallurgical process that includes the cementation of Pb using Zn and Al powder. The process consists of three key stages: acidic washing of zinc, alkali leaching, and the subsequent cementation of lead using zinc and aluminum powder. The effects of various parameters such as powder amount, temperature, reaction time, and stirring speed on the reaction kinetics were systematically examined. Optimal separation conditions were determined for both zinc and aluminum powder, with Pb cementation achieving 97.56% and 99.95% respectively, under specific conditions. Additionally, a kinetic study was conducted to evaluate the reaction mechanisms and activation energies associated with Pb cementation using zinc and aluminum powder. The results indicated that Pb cementation was powder-controlled in both cases, with reaction activation energies of 8.6 kJ/mol and 4.6 kJ/mol using zinc and aluminum powder, respectively. Furthermore, the use of aluminum powder demonstrated several advantages including enhanced performance, high purity of Pb product, and reduced powder consumption. This research advances the optimization and understanding of Pb recovery processes from ZPR, emphasizing the potential of aluminum powder as a promising alternative for effective lead cementation.

探索通过湿法冶金工艺从锌厂残渣中可持续回收铅：锌粉和铝粉固结的比较分析

本研究探讨了从锌厂残渣（ZPR）（特别是浸出滤饼（LFC））中回收和制备铅的方法，采用的水冶工艺包括使用锌和铝粉固结铅。该工艺包括三个关键阶段：锌的酸洗、碱浸出以及随后使用锌和铝粉固结铅。系统研究了粉末量、温度、反应时间和搅拌速度等各种参数对反应动力学的影响。确定了锌粉和铝粉的最佳分离条件，在特定条件下，铅的胶结率分别达到 97.56% 和 99.95%。此外，还进行了动力学研究，以评估使用锌粉和铝粉进行铅胶结的相关反应机制和活化能。结果表明，两种情况下的铅胶结都是由粉末控制的，使用锌粉和铝粉时的反应活化能分别为 8.6 kJ/mol 和 4.6 kJ/mol。此外，铝粉的使用还显示出一些优势，包括性能更强、铅产品纯度更高以及粉末消耗量更少。这项研究推动了对 ZPR 铅回收工艺的优化和理解，强调了铝粉作为有效铅固结替代品的潜力。

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
