Barite (BARIUM) Introduction Barite is a mineral composed of barium sulfate, BaSO 4. It is usually colorless or milky white, but can be almost any color, depending on the impurities trapped in the crystals during their formation. Barite is relatively soft, measuring 3-3.5 on Moh's scale of hardness. It is unusually heavy for a non-metallic ...

Oct 05, 2018· Once Sr is incorporated into the barite lattice, it is unlikely to be leached out regardless of the surrounding environment because of the strong crystal stability of BaSO 4 for Sr immobilization. Considering its high Sr removal and retention efficiencies, barite is a reliable material for Sr removal from aqueous solutions.

Barite. Barite often occurs as large veins or beds, as gangue mineral in various mineral veins, in limestones, sandstones and like deposits. The ores are generally low grade and require concentration by flotation to meet market specifications. Barite, a very common barium containing mineral, has a certain glassy gloss.
