Improvement of iron removal from silica sand …
Although grinding of the untreated silica sand would have improved iron removal by increasing the surface area, it would consume energy and cause particulate pollution. Hence the silica sand was subjected to our work without prior grinding. The influence of pH of the initial solution, which has been confirmed by many workers, would not be discussed in this paper.
