Nov 19, 2018· Using a pyromorphite as a lead ore is less common. Lead is a widely used commodity, with an annual worldwide production in the tens of billions of pounds. About 80 % of the use of lead is in lead-acid batteries, but it is valued in other industrial applications for its density and ability to combine with other elements.

Galena is the most abundant lead mineral, has been mined for millennia, and remains our major source of that metal. It is a metallic, lead-gray mineral with cubic cleavage and a distinctly high density that makes galena samples feel much 'heavier' than expected for their size. Because it melts at a relatively low temperature and is so ...
