Lead Smelting - Base Metal Smelting

1) The galena is roasted (reacts with O2) in order to remove the sulfur component of the metal sulfide [2]. Roasting is a method where a sulfide ore (i.e an ore containing PbS) is heated in air which converts the metal sulfide to either a metal oxide or a metal itself [3]. Word Equation: Lead (II) Sulfide + Oxygen à Lead (II) Oxide...
