Summary of the Silica Sand Processing Plant Equipment. In general most silica sands can be beneficiated to acceptable specifications by the flowsheet illustrated. Reagent cost for flotation is low, being in the order of 5 to 10 cents per ton of sand treated.
Plasma outside deposition (POD) For this process a plasma heat source is used to "burn" chemical precursors and deposit a thin glass layer on a rotating target. The target can be a tube or a solid rod, it is not necessarily round. Because of the high temperature of the plasma, this process is best suited to produce fluorine doped fused silica.
Extraction of Silica from Rice Husk 72 D. Proposed Process This is new process, silica is manufactured by using rice husk ash as a source of silicate or silica and this ash is then reacted with sodium hydroxide which yields the sodium silicate, which on further reacting with sulphuric acid gives silica along with by-product sodium sulphate.

In terms of chemical composition, silica glass is the simplest amorphous substance that has been commercially utilized in many fields of application in a number of industrial branches, thanks to its physico-chemical properties.
In industrial glass: Silica-based …of silica is known as silica glass, or vitreous silica. (It is also called fused quartz if derived from the melting of quartz crystals.) Silica glass is used where high service temperature, very high thermal shock resistance, high chemical durability, very low electrical conductivity, and good ultraviolet transparency are desired.…
Glass manufacturers do not generally operate activities and/or processes that generate Respirable Crystalline Silica on-site .The glass industries' on-site processes only include handling and mixing of raw materials and their transportation to the glass furnace without further processing that may generate significant amounts of smaller particles.
Typical process until precision product is completed. Note) Since silica glass might be damaged due to a processing distortion, thermal treatment called "annealing" which removes the distortion between the processes is required, but in here such process is left out.

Fused quartz or fused silica is glass consisting of silica in amorphous (non-crystalline) form. It differs from traditional glasses in containing no other ingredients, which are typically added to glass to lower the melt temperature. Fused silica, therefore, has high working and melting temperatures.
