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!
