Baryte: Barium Sulphate 
(copyright theimage.com)







Baryte (BaSO4)


Baryte is generally colourless to white but yellow, red and brown forms can be found due to the inclusion of bituminous matter. Lustre is vitreous to pearly. Baryte has perfect prismatic cleavage 
and a hardness of between 3 and 3.5. Crystals are usually tabular or prismatic but massive, 
 fibrous, granular varieties can be found. Baryte tends to occur as a gangue mineral in medium  
and low temperature hydrothermal veins associated with lead, silver, copper and zinc. It also  
forms as nodules in limestones and dolomites. World class deposits found in England (Derbyshire), 
 the former Czechoslovakia, Romania and Germany.



Uses: The main ore of  barium. Also used in the drilling industry as a drilling mud, and the 
 paper and rubber industries.
