Barite is a mineral composed of barium sulfate, with the chemical formula BaSO₄. This mineral is primarily recognized for its high density, which distinguishes it from other non-metallic minerals. Baryte generally occurs in shades ranging from white to gray, sometimes yellowish, bluish or reddish, and is frequently found in tabular, prismatic crystals or fibrous masses.
Crystallizing in the orthorhombic system, baryte often forms flat or lamellar crystals. With a hardness of 3 to 3.5 on the Mohs scale, it is relatively soft and brittle.
