Baryte, the natural compound of barium sulfate (BaSO₄), is a common mineral found in veins that typically occur alongside quartz and calcite. It is also present in limestone and sandstone.
Characteristics of Baryte
The defining characteristic of baryte is its high density compared to other non-metallic minerals. Baryte usually appears in colors ranging from white to light gray, but it can also display blue, brown, or black hues. It is an opaque, dark mineral with a vitreous luster.
While first-grade baryte is often seen as rectangular crystalline formations, commercially produced baryte is commonly found in granular or crystalline block forms, or as fragments. The specific gravity of baryte typically ranges between 4.3 and 4.6, and its hardness can vary significantly depending on the region of production.
Applications of Baryte
Baryte is primarily used in the oil and gas industry as a weighting agent in drilling fluids. Its density helps to balance the pressure exerted by the well during drilling. Additionally, baryte is used in the production of paints, plastics, and rubber due to its high specific gravity and non-reactivity. It also has applications in medical imaging as a contrast medium and in radiation shielding.
