Galena | Common Minerals

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 ...

About: Gangue

In mining, gangue (/ɡæŋ/) is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit. It is thus distinct from overburden, which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed, and from tailings, which is rock already stripped …
