Lead and Zinc Metallurgy
Lead is, of course, a primary component in lead-acid batteries, whereas zinc is used in galvanized steel and as an activator in the vulcanization process for tires. The two metals are closely connected, starting with their mineralogical occurrence in combined lead-zinc ores (i.e., combi-nation of mainly lead sulfide, zinc sulfide, iron sul-
