Abstract
Finely divided lead ores to be worked up by a roasting reaction process are agglomerated, with or without a binder, and the agglomerates are consolidated by heating them, for example by the passage therethrough of hot gases which may be combustion gases or the waste gases of the lead hearth. In an example, fine galena, with or without a binder, is mixed with flue dust, lime, and coal and briquetted by means of a press or the like, and the briquettes are heated at from 200 DEG C. to over 400 DEG C. Waste gases from the lead hearth may be passed over or through the briquettes on a conveyer or in a shaft. The circulation of the heating gases may be wholly or partially cyclic. The process is also applicable to flotation ores which may be agglomerated and mixed with fuel or dusted with a coating of fuel.
