The barytine is a white mineral,colorless,grey,brown,blue or red that you can find in the sedimentary rocks.This rock is compound by 65,7 p.100 of baryum oxyde(BaO) and of 34,3 p. of sulfer trioxyde(SO3). The commercial deposit can be found in the form of strates,seams,cavity or in the  residual form.Since the barytine has a high level density,that it's soft,chemically inactive and that it's price is low,we mainly use it for the forage of oil and natural gaz.Because it's very pale and low sparkling,we use it also for plastic and paints.it can also be used for making caoutchouc,friction materials and carpets,to absorb noises.Because the barytine can absorb the gamma ray,we use it to build anti-radiation screen for the buildings that have nuclear reactors.The pharmaceutical level(high purity)is also used for radiography.Barytine can also be used for melting,for oxydising or to bleach the glass.The baryum carbonate(BaCO3)is a secondary product that can be used for the fabrication of television glass,or for optical glass,for ceramic and porcelain.

You can find 4 barytine mines operating in Canada:2 in Britsh-Columbia(mainly for forage and paint),,one in Ontario(for  paints,plastic and for lubrification.and one in Nova-Scotia(high pharmaceutical level).In 1997,the Canadian production for the barytine was 76 955 t and the shipping was 84 091 t for a total of 7 118 m $.
