Abstract

Physical and chemical analysis of the two samples A and B of Azara baryte were conducted, such as moisture content, loss on ignition and elemental composition by the use of atomic absorption spectrophotometer(ASS) and flame photometer. The oxides values in 1.000 g sample of each element were obtained. Sample A (lower layer): moisture content = 0.020, loss on ignition = 0.060, Na₂O = 0.250, K₂O = 0.015, CaO = 0.014, MgO = 0.018, Fe₂O₃ = 0.029, SiO₂ = 9.310, BaO = 89.630, Al₂O₃ = 6.200 Sample B (upper layer): moisture content = 0.030, loss on ignition = 0.040, Na₂O = 0.030, K₂O = 0.001, CaO = 0.006, MgO = 0.030, Fe₂O₃ = 0.028, SiO₂ =18.12, BaO = 65.020, Al₂O₃ = 16.120. The result of the analysis revealed that the Azara baryte could use as source of inorganic chemical oxides and for the production of some laboratory chemicals such as barium sulphate and aluminum oxides
