Blast Furnace Process - an overview ScienceDirect Topics

2010-1-1  The zinc blast furnace process is one of the newest pyrometallurgical processes developed by Imperial Smelting Processing Limited in England. In the ISP, ZnO is reduced by carbon to produce zinc. In the reduction carried out by an ISP blast furnace, the zinc that is evolved in the form of a vapor is condensed by using molten lead.
