Galena, in recent times, is counted as the most important lead ore which helps in the production process of goods. Back in 77 A.D. This mineral was first discovered by Gaius Plinius Secundus. The mineral is named after the Latin word which means "lead ore". A relatively low melting point is needed to melt the mineral, Galena.

Galena (PbS) is the most important lead-bearing mineral and a major source of lead metal worldwide. As a sulfide mineral, galena often coexists with other valuable sulfides such as chalcopyrite (CuFeS 2) and sphalerite (ZnS), as well as the gangue mineral pyrite (FeS 2) [1].The separation of galena from these other minerals is accomplished through froth flotation [2], …

The most common ore mineral of lead mined in the United States is galena with the chemical symbol PbS. Galena is lead sulfide with a hardness of 2.5 on the Moh's scale - actually quite soft- but it is VERY heavy with a specific gravity of 7.4 to 7.6. To put that in perspective, it weighs about 700 pounds per cubic foot!
