The use was investigated of ultrasonic power to remove Fe-rich coatings from the surfaces of silica sand samples from the Ganqika deposit, Inner Mongolia, for use in glass making. The results showed that removal rates as high as 52.7% could be achieved in 10 minutes using a combination of wash water and ultrasound, significantly more than for mechanical scrubbing. Equivalent removal rates were achieved in 5 and 15 minutes for ultrasonic and mechanical scrubbing treatments, respectively. Additions of chemical reagents such as Na2CO3, Na2SiO2, (NaPO3)6 and AlCl3 increased the removal rate by 15%-30% during ultrasonic treatment., The use was investigated of ultrasonic power to remove Fe-rich coatings from the surfaces of silica sand samples from the Ganqika deposit, Inner Mongolia, for use in glass making.
