Iron is a key detrimental impurity in silica sands that determines their contribution to high-technology industries. Herein, a simple ecologically sound approach is investigated for iron removal from a silica sand sample obtained from the El-Zaafarana area-Egypt. The sample was subjected to a detailed microscopic mineralogical study

Furthermore, Fig. 4 shows that the maximum removal of 75.4% of iron with ultrasound, is increased by 16.3%, in comparison with that without ultrasound when the acid concentration is 4 g/l for the same period of 30 min. The maximum removal of 65.8% of iron is achieved with the solutions containing 6 g/l of oxalic acid for 30 min under ...
