Baryte Mining Process | Equipment | Flow | Cases - JXSC

Baryte is a mineral consisting of barium sulfate (BaSO4). baryte is generally white or colorless and is the main source of barium. The barite group consists of baryte, celestine (strontium sulfate), anglesite (lead sulfate), and anhydrite (calcium sulfate). Baryte and celestine form a solid solution (Ba, Sr)SO4.

Barium chloride | BaCl2 - PubChem

Barium stimulates striated, cardiac, and smooth muscle, regardless of innervation. It is antagonistic to all muscle depressants, no matter whether they act primarily on nerve or muscle. Initial stimulation of contraction leads to vasoconstriction through direct action on arterial muscle, peristalsis through action on smooth muscle, tremors and cramps through action on the skeletal muscles, and ...

MERCURY REFINING COMPANY, INC.

Barium is the heaviest of the alkaline earth metals. Barium chloride and nitrate are water soluble, while carbonates and sulfates of barium tend to be much less soluble. In natural water environments barium primarily forms insoluble carbonate and sulfate compounds. Thus, dissolved barium is found only in trace amounts in surface and ground waters.
