aluminum separation from silica sand

Separation of aluminum and silica from coal gangue

2015-5-1  The effect of the liquid–solid ratio on the acid leaching behaviors of aluminum, iron, and silica is displayed in Fig. 3. A huge increase in aluminum extraction rate from 45.64% to 97.3% can be observed with the rise of the liquid–solid ratio from 1:1 to 3:1 As a result, the silica content in the leached residue increases from 75.27% to 98.01%.
