    Recent Developments In Slagfuming

    with a view to recovering zinc from lead blast furnace slag. In earlier attempts, the idea of reducing zinc oxide to metallic zinc and then to fume was abandoned after trying compressed air blast without fuel. In 1925, the Waelz process of treating oxidised zinc ores for the recovery of zinc oxide was started in Germany. This method could not ...
