Silica | Minerals Education Coalition
Silicon (Si) is a semimetallic or metalloid, because it has several of the metallic characteristics. Silicon is never found in its natural state, but rather in combination with oxygen as the silicate ion SiO 4 4 in silicarich rocks such as obsidian, granite, diorite, and sandstone. Feldspar and quartz are the most significant silicate minerals.

Studies on extraction of phosphorus from phosphate ore by ...
The results showed that the activation energy of the reaction using potassium feldspar as a fluxing agent was lower than that of the traditional process with silica and silicon dioxide. Therefore, higher extraction of phosphorus and energy conservation can be achieved by using potassium feldspar as fluxing agent, instead of silica, in a phosphorus furnace.

Chemistry of Silicon (Z=14) Chemistry LibreTexts
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.

How DNA extraction kits work in the lab Bitesize Bio
The final step in the DNA extraction protocol is the release of pure DNA or RNA from the silica. For DNA extraction, 10 mM Tris at pH 89 is typically used. DNA is more stable at a slightly basic pH and will dissolve faster in a buffer than water. This is true even for DNA pellets.
