Method for obtaining metallic lead from minerals, intermediate products or residues containing lead sulphide, according to the roasting reaction procedure, characterized in that the material to be treated is synthesized together with waste and/or flying dust, being subjected to this particular to an oxidant or sulfatant roasting, which accumulates an amount of oxygen combined chemically in the raw material, which exceeds that required for the performance of the reaction process by roasting, and heating the synthesized material, in the addition of other participants in the reaction, up to the temperature of the raction, whereby the charge reacts itself, forming volatile combinations of sulfur, and metallic lead.
