Metallurgy — lead processing A zinc-lead blast furnace and lead-splash condenser. This technology is utilized mainly for producing zinc while managing both lead and zinc from raw materials, a technique that was highly influential in 20th-century smelting.

Galena (PbS) is considered the most important primary ore of lead because it is the most widely distributed and significant source of the metal globally. While lead can be found in other minerals, such as cerussite and anglesite, these are secondary minerals that typically derive from the weathering of galena.123

Galena is highly valued not only for its lead content—which is 86.6 percent in its pure form—but also because it frequently contains other commercially significant elements, including silver, zinc, copper, and antimony. In many instances, the value of the silver found within galena deposits exceeds the value of the lead itself, making it a vital resource for multiple metals. Because of its prevalence and the economic benefit of these associated minerals, galena remains the primary focus of lead processing operations worldwide.123
