Abstract

The recovery of lead from galena by leaching is complex, primarily because the dissolution kinetics is very slow in most of the means of leaching and chlorine gas produced in the reduction stage. In contrast, cementation with iron to produce lead is a very attractive because it has fast kinetics and is a selective process in the middle chloride. Research In studying the reduction of lead in castiron in an electrochemical cell using iron electrodes. We studied the procedure of the electrodes during the reduction of lead. The objective is to analyze the mechanism of the reaction of iron particles using the fundamentals of electrochemical kinetics based on the anodic and cathodic reactions that cause potential differences in the surface and from the results, analyze the reduction of lead in aqueous media.
