The Recovery of Zinc and Lead from Blast-Furnace Slag at Trail, B. C.

THE development of the method for recovering zinc from lead blastfurnace slags at Trail is interesting and important in the history of both lead and zinc metallurgy. Many efforts have been made in the past, particularly in Germany, to make economic recovery of zinc from slag. The Pape process on Oker slags was successful and is being worked at the present time. More recently the Waelz process has come to the fore.
