| 摘 要： | Effects of various technological conditions such as ρ(C1^- ), ρ(Fe)T, pH value and temperature on the cell voltage, lead leaching rate and the cathodic current efficiency of the slurry electrolysis of high-silver galena concentrate were studied, and the behavior regularity of lead and silver was investigated. As a result, the suitable condition was determinedas, ρ(C1^-)230g/L, ρ(Fe)T15g/L, pH 1, temperature 70℃, electrolysis time 6h. Under such condition,adopting the cathodic current density of 150 A/m2 and the liquid-solid ratio of 15 : 1, lead powder with a purity degree of 91. 18% was got. At the same time, leaching rate of lead, leaching rate of silver and cathodic current efficiency amounted to 96.88%, 70.88% and 75.68% respectively.
