Witherite is a barium carbonate mineral, BaCO3, in the aragonite group. Witherite crystallizes in the orthorhombic system and virtually always is twinned. The mineral is …
The Mineral witherite. Witherite is an uncommon mineral, especially since it easily alter s to the more common mineral Barite. It alters when sulfuric acid from sulfide minerals dissolves the Witherite, and the sulfur combines with the barium to form Barite.

Witherite is identified by the fact that it is very dense for a nonmetallic mineral (a property shared with baryte) and its effervescence in dilute hydrochloric acid, demonstrating that it is a carbonate.
