Abstract
Procedure for separately recovering lead richness and sulfur richness from minerals or lead sulphide concentrates without prior sintering, characterized in that it comprises: loading ore or lead sulphide concentrate, in particulate form and mixed with a gas rich in oxygen, containing at least approximately 60% oxygen, downward, inside an oven and through the combustión zone to impinge on the surface of a molten bath, entering it, whose bath has richness of lead in the form of slag with lead oxide content derived from said manufacturing process, whereby the oxidation of said lead sulphide is initiated and sustained to produce lead oxide and sulfur dioxide in a flame in said area of combustión above the area of incidence or collision on said molten bath and, after said collision, the oxidation of residual lead sulphide continues by reaction within the molten slag; supply the gas with sufficient oxygen, first to provide oxidation heat and maintain said flame at a temperature of at least 1300ºC and said molten bath at a temperature above 1100ºC and, second, to maintain at least one 35% lead as lead oxide in the slag, said heat of oxidation being achieved by reaction with said oxygen-rich gas; and extracting from said furnace molten material containing lead riches with a low content of sulfur and gaseous material containing richness of sulfur and vapors of occluded lead oxide.
