The high SiO2 content (59.26 wt%) compared to theoretical value (46.54 wt%) of well-ordered kaolinite is due to excess silica and this has been revealed in XRD pattern as quartz peak.

In this article, a simple chemical process is described which uses a non-conventional raw material rice husk ash for extraction of silica. Rice paddy of (husk ash) is one of the most silica rich raw materials containing about 90-98% silica (after complete combustion) among the family of other agro wastes.

silica content of this concentrate was 1.7 pct. An additional sample from the southern Oregon area was obtained from the black sand deposits along the coast. This was a relatively low-grade high-iron concentrate with a Cr:Fe ratio of 1.2:1. The silica content of this material was low, however, at 0.75 pct.

(silica) present in the bauxite causes caustic soda loss in the Bayer process. The part of total silica which reacts with caustic soda and forms sodalite complex through sodium silicate route is termed as Reactive Silica. Thus, the non-reacting component of total silica with caustic soda is also known as Non-Reactive Silica.

(2011). The flowsheet described above is commonly referred to as the "RKEF process" (Walker et al., 2009) due to its use of rotary kilns (RK) and electric furnaces (EF).

Geochemists also use the term "silica" to refer to the overall silicon and oxygen content of rocks. This is confusing, but stems from the fact that in rock analysis and sample is dissolved, the solution treated, and the amount of silicon present is determined by precipitating it as silica. So a geologist may say "This rock is 48% silica".
