Air Flow Effect on The Dissolution of Iron in Tin Slag Using Hydrochloric Acid
In this research, air flow effect on dissolution of iron from tin slag using hydrochloric acid was investigated.Tin slag was ground to particle size -100 mesh and leached with variation of acid concentration. Leaching filtrate then analyzed with Atomic Absorption Spectroscopy (AAS) to determine the extraction percentage. This method was modified using air flow and compared to each other. Result showed that acid leaching using airflow gave higher iron extraction percentage compare to acid leaching. Acid leaching using airflow gave iron extraction percentage 81,69 persen in acid concentration 5 persen while acid leaching without airflow gave iron extraction percentage 43,25 persen in the same acid concentration.
