中文摘要: 在分析湿法炼锌铅银渣的主要成分与化学物相的基础上,考察了温度、浸出时间、氯酸钠浓度、酸度等对铅银渣中铅银含量及浸出率的影响,确定了氯化浸出最优工艺条件为:氯化钠浓度300 g/L、氯化钙浓度50 g/L、初始盐酸0.4 mol/L、浸出温度85 ℃、浸出时间2.5 h、液固比8,在该条件下铅银渣中铅、银的浸出率分别可达94.43%和91.48%,渣中铅含量为0.9%,银含量84.4 g/t。
Abstract:Based on analysis of composition and chemical phases, effects of temperature, leaching time, sodium chlorate concentration, and acidity on lead and silver extraction from lead-silver residue produced in hydrometallurgical zinc refinery were investigsted. The results show that leaching ratio of lead and silver is 94.43% and 91.48% respectively, and lead and silver content in residue is 0.9% and 84.4 g/t respectively under the optimum conditions including NaCl concentration of 300 g/L, CaCl2 concentration of 50 g/L, initial HCl concentration of 0.4 mol/L, leaching temperature of 85 ℃, leaching time of 2.5h, and L/S=8.
