Barite is barium sulfate with the chemical formula of BaSO4. Unlike barite witherite (BaCO3) it is not chemically inert, it can dissolve in water and, when dissolved, can cause an environmental hazard. Barite forms in many geologic environments with both metallic and nonmetallic minerals. Minerals associated with the ore are a main concern when mining and processing barite.
