12%Chert has formed from two sodium-silicate minerals, magadiite (NaSi 7,O 13 (OH) 3 ·3H 2 O) and kenyaite (NaSi 11 O 20.5 (OH) 4 ·3H 2 O), in uppermost Pleistocene deposits of lakes Magadi and Natron in Kenya and Tanzania. The chert consists of finely crystalline quartz and characteristically forms nodules of irregular shape with white coatings having reticulate surface patterns.

hydroxide ion, and sodium ion. The silicate solutions also contain crystalloidal silica which was thought to be the components of the known crystalline sodium silicates, charged aggregates of these unit structures and silica, or definite complex silica ions (Encyclopedia of Chemical Technology, 1982).
VRX Silica has acquired high-quality silica sand projects at Arrowsmith, located 270km north of Perth in WA, and at Muchea, 50km north of Perth. Both locations have the potential for substantial Mineral Resources and benefit from adjacent rail lines...
Sodium silicate glass is made by fusing high purity silica sand and soda ash in open hearth furnaces at 1300°C. The molten glass is cooled, fractured, and dissolved under pressure with hot water and steam.
and sodium silicate have given satisfactory laboratory results. This prior investiga tion suggested that the soil-lime-sodium silicate reaction was such that the final strength of the stabilized soil depended on the elapsed time between the mixing of the soil-lime-sodium silicate-water combination and the final compaction of the mixture (6).

acid, silicate is generally poorly retained by anion ex-change columns. Because it has almost no dissociation at pH 7, the ion cannot be determined by suppressed conduc-tivity detection. As a weak acid, it is adequately retained by anion exchange, eluting later than fluoride. Silicate can be derivatized post-column with sodium molybdate
