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 supported by XRD and XRF …
Mechanical scrubbing is the removal of iron from the surface of quartz sand and iron-containing minerals adhering to the surface of quartz sand by means of mechanical external force and collision and friction between sand particles. Currently, scrubbing techniques are primarily rod scrubbing and mechanical scrub…See more on lzzgmachine
