Abstract: Lead is obtained from lead sulfide ores or concentrates without prior sintering or roasting by the steps of adding the lead sulfide to a molten slag, injecting sufficient oxide to below the surface of the molten slag and vigorously agitating the slag whereby substantially to oxidize the lead sulfides to lead oxides, and then reducing the lead oxides. The slag is preferably agitated by means of a lance. The reduction stage may follow the oxidation stage in the same vessel or may be conducted in another vessel.
