Abstract EN
The bauxite produced from Al-Ga ‘ara area in Al-Enbar containing 50.4 W percentages A1 was used for a a! urn/na production.
For a-alumina product ion bauxite was mixed with calcium carbonate in a ratio 1.3 and the mixture was burned at temperature range 1150- cooled to 500°C; crushed and ground.
The powder produced treated then with 6% sodium carbonate solution using different temperature (60-100°C) for fifteen minutes.
After filtration, the produced sodium alurninate solution was reacted with 2% of calcium hydroxide at 98 for thirty minutes.
The filtrate was carbonated with pur(f led CO gas at 70°C for different times (30- and different flow rates (20-80 cm’/min).
Alumina was precipitated as hydrate, then washed with water, dried at 110°C, and calcined at 1200°C.
The produced a AL was ident?fied by X-ray diffraction.
