Silica extraction from Biomass Leaf Resources Limited Many plants contain silica, and some products of agriculture, for example, rice husks, contain as much as 10% silica by dry weight. Rice husk is the outermost layer of rice grain that is separated from the food product in a milling process.

Silica is the most prevalent form of naturally occurring silicon. Silica is a strongly bonded compound and it requires a good deal of energy to extract the silicon out of the silica complex. The principal means of this extraction is via a chemical reaction at a very high temperature. The synthesis of silicon is fundamentally a two step process.
