Barite ores in Eastern Desert

 

 

Barite formed in the nature from barium sulphate (BaS04). Barite is one of the main natural constituents of the muds used in drilling of wells. The most distinctive features of barite is its highly specific gravity which supports its use as a weighing agent. Other desirable properties regarding its use as an additive in drilling fluids are its low abrasiveness, chemical stability and  lack of magnetic and toxic effects.

 

: Barite Uses

                                                                            1- Heavy matter in drilling fluids.

  2- Barium chemicals which uses in the industries of:

<!--Paints.

<!--Paper.

<!--Rubber.

<!--Ceramics.

<!--Glass .

3- Crushed barite used in coating process of gas and oil linepipes extended under the water.

             XRD and chemical analyses prove that barite samples of the Eastern Desert are almost pure (93.94-95.4 % BaS04). They are composed of barite with occassional quartz , feldspar ,calcite , fluorite, geothite, hematite and clay minerals. Iron oxides and clay minerals might be related to altered sulphides and feldspars. On the other hand, samples of Bahariya Oasis repersent low grade barite ( 62.6-82.3 % BaSO4). They are composed of barite with occassional quartz, feldspar, calcite,geothite,hematite and kaolinite. They relatively high Ti

(100-6000 ppm) and Mn (50-80 ppm) in Bahariya samples might be attributed to sedimentary processes facilitating their enrichment.
