Sandstone is a type of rock made from sediment — a sedimentary rock. The sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock. It is composed mostly of sand particles, which are of medium size; therefore, sandstone is a medium-grained clastic sedimentary rock. …
Silica. Also called silica sand or quartz sand, silica is silicon dioxide (SiO 2). Silicon compounds are the most significant component of the Earth's crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source.

The "separate bed" principle consists of two resin tanks that are installed in series. For silica extraction, the first tank consists of a cationic resin bed that must be regenerated with an acid solution. The passage of the silica through the cationic tank alters its composition and "converts" it into silicic acid.
