WO1988001654A1

Lead-zinc complex sulphide ores or concentrates are treated by a process which comprises: a) adding the ore or concentrate to a bath of molten matte which is overlaid by a slag layer; b) agitating and heating the bath by submerged injection of a fuel and air (or other oxygen-bearing gas mixture), c) adding a reductant to the bath; thereby to convert at least a substantial proportion of the ....
