In this lecture, we will be discussing the Auto Reduction - Lead Extraction
Highlights:
In the reverberatory furnace, galena is dropped and roasted in which PbO and PbSO4 are formed
When black mass changes to white, roasting is stopped by closing the air windows and from the top, more PbS is dropped which leads to auto reduction
