How To Get Sulfur

Sulfur is the brimstone of the Bible and has been known for thousands of years. Sulfur atoms are pretty common and occur in many minerals. The most prized for sulfur extraction is pyrites (fool''s gold). Despite its abundance in nature, obtaining useful sulfur (somewhat pure sulfur) is going to be a big hurdle for most people post SHTF.
