Chemical oxides analysis from Azara Baryte

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
