PROCESSO PARA A PRODUCAO DE CHUMBO METALICO

A process for the production of metallic lead comprising the steps of: (1) halogenating lead sulfide with chlorine, bromine or gaseous fluorine at a temperature between 90º and 120º c, (2) leaching the treated mixture with brine, (3) filtering the resulting solution to separate the elemental sulfur,...

Zusammenfassung:A process for the production of metallic lead comprising the steps of: (1) halogenating lead sulfide with chlorine, bromine or gaseous fluorine at a temperature between 90º and 120º c, (2) leaching the treated mixture with brine, (3) filtering the resulting solution to separate the elemental sulfur, the residue and the soluble lead halide, (4) crystallizing said lead halide, and (5) recovering the metallic lead by electrolysis.
