Azara baryte was subjected to analysis, revealing an average specific gravity of 4.3 g/cm³ and a loss on ignition of 1.71 wt%. The contents of Fe2O3, Al2O3, and BaO were determined using atomic absorption spectrometry. Gravimetric methods were employed to measure SiO2 and SO3, while flame photometry was utilized for the determination of CaO, MgO, Na2O, and K2O. The average percentage values for the chemical oxides in the baryte samples were as follows: BaO (57.29 wt%), SO3 (25.99 wt%), CaO (1.40 wt%), MgO (0.40 wt%), Fe2O3 (3.46 wt%), Al2O3 (0.97 wt%), Na2O (2.82 wt%), K2O (0.30 wt%), and SiO2 (6.23 wt%). These findings indicate that Azara baryte meets the requirements for use in glass production and as a filler or extender in paint and rubber production. However, further beneficiation is necessary for it to be suitable as a component of oil drilling mud
