Enviroplas Technology for the Recovery of Lead and Zinc

The extraction of zinc and lead from liquid slags from lead blast and imperial smelting furnaces direct into a lead splash condenser may offer an economically attractive alternative to fuming zinc and lead as oxides since these oxides require further treatment to produce metal Mintek conducted four campaigns during 1994/95 on the 5 6 MVA multi purpose demostration scale
