Preparation of Pharmaceutical Dried Aluminium Hydroxide Gel from Iranian Nepheline Syenite

In the first step of this research we produced Aluminium hydroxide from nepheline syenite ore using of a pyrometallurgical and hydrometallurgical method. We dissolved aluminium hydroxide in the sulphuric acid and added the obtained aluminium sulphate to potassium hydrogen carbonate solution. Product was washed with water and ethanol carefully and its solvents were emitted by centrifuge method. Resulting gel was dried between 40 °C -50 °C.
