Abstract EN
Alumina has wide industrial and technological applications that can be extracted from different locations, different methods and materials.
Kaolin from Iraq Alduikhla astrologer has used as a raw material source for alumina production.
The alumina concentration in the Iraqi kaolin is more than 34% which considered as a good replacement for bauxite rack.
Crushing andground is the first process to reduce the kaolin particle size to the micron level which increases the surface area of kaolin.
The kaolin is heat treated at different temperatures (600, 650, 700 and 750) ̊C for 2 hours to remove some of ithe mpurity like organic materials and crystal water before acid treatment.
A different concentration of hydrochloric acid (pH) (0.45, 0.5, 0.55, 0.6 and 0.65) has used for extraction of alumina from kaolin.
The reaction between the hydrochloric acid and kaolin has studied at different temperature (30, 60 and 90) ̊C.
The extraction of alumina has decreased with increase t inhe reaction temperature.
Finally t,,he alumina extraction by this method has characterized using XRD and XRF to investigation the crystal structure and the amount of impurities presented there.
The final extracted alumina h isaving cubic crystal structure (γ alumina) with purity above 95%.
