Galena is an ore of which metal?

Galena is recognized as the primary ore of lead. Its chemical composition is primarily lead sulfide (PbS), making it not only a significant source of lead but also an important mineral in various industrial applications. When mined and processed, galena undergoes roasting to convert it into lead oxide, which can be further reduced to yield pure lead metal.

The association of galena with lead is well-documented in mineralogy and mining, which often highlights its historical significance as a vital source of lead. This strong connection underscores why lead is the correct answer.

In contrast, the other options like copper, zinc, and iron correspond to different ores — chalcopyrite for copper, sphalerite for zinc, and hematite or magnetite for iron — and do not hold any association with galena. Understanding the characteristics and composition of galena clarifies its importance specifically as a lead ore.
