The production of primary lead is a process of extracting lead from lead sulfide concentrate by smelting. Smelting process mainly includes sinter plant–blast furnace route and direct smelting reduction process as shown in Figs. 2 and 3, including oxidation, reduction, and refining (Sohn and Olivas-Martinez, 2014) sinter plant–blast furnace route, PbS is oxidized
Lead acid batteries are processed mainly by using pyrometallurgical operations with problems related to SO2 evolution. Many efforts have been devoted to solving this concern. In this work, where only the anode preparation was a pyrometallurgical process, this problem has been overcome by limiting the process temperature. Several tests have been carried out in

A lead acid battery consists of a negative electrode made of spongy or porous lead. The lead is porous to facilitate the formation and dissolution of lead. a process known as the "gassing" of the battery. If current is being provided to the battery faster than lead sulfate can be converted, then gassing begins before all the lead sulfate is
