Laboratory Investigations on the Behavior of Accessory Elements in Lead Blast Furnace Smelting

摘要

The effect of slag composition on lead losses to slags and on the behavior of associated accessory elements in lead blast furnace smelting has been studied. Equilibrations of 30 g of lead and synthetic slag doped with Cu, In, Tl, and Sb at 1,200 C in CO-CO2 atmospheres revealed the importance of the FeO:SiO2 ratio and the basicity ratio, (CaO+MgO):SiO2, of the slag.
