processing of silica to remove iron content

Jul 01, 2007 Improved iron elimination can be obtained on processing natural silica sand with the ultrasound technology. Under the same conditions, the effect of iron elimination, E, is as high as 52.7% in 10 min, which is raised by 45.2% compared with the scrubbing technology. The effect of iron elimination in 1–5 min is equivalent to that with ...

how to extract iron from silica efficiently

Iron is extracted from its ore in the blast furnace.. The main iron ore is called haematite. Haematite is iron(III) oxide - Fe 2 O 3. The iron ore contains impurities, mainly silica (silicon dioxide). Limestone (calcium carbonate) is added to the iron ore which reacts with the silica to form molten calcium silicate in the blast furnace.

It is essential to control the iron content to be minimum as much as possible, at least about 0.05 ppm, in order to avoid corrosion and scale formation. The silica scale formation usually takes place at pH level below 8.5, whereas Magnesium silicate scale

Water Treatment of Silica. Natural waters, generally, contain about 5-8 mg/l of silica (Si0,). Another important source of silica in water is the sand watertreatments filter.When water treated by lime-soda process is filtered through a sand water filter, a good amount of silica dissolves in it (forming calcium and magnesium silicates) due to alkaline nature of waters.
