Removal Iron from Silica Sand to Get High Purity of Silica

It is found that the iron on the surface of silica sand and matrix of silica sand can be eliminated more efficiently by sonication than by mechanical scrubbing. Furthermore the iron elimination rate can be raised when the sonication combine with chemical process, such as the iron elimination use acid leaching process [5] .
