A method is provided for treating silica sand scrubs (SSS) generated and accumulated as waste in the chloride manufacturing process of titanium dioxide pigment. A hydrothermal process is used to produce sodium silicate solutions of modulus 3.0 to 3.8, and precipitated silicas. In some embodiments, the process uses two specific principal reaction stages.
Water Treatment of Silica. Natural waters, generally, contain about 5-8 mg/l of silica (Si0,). Another important source of silica in water is the sand watertreatments filter.When water treated by lime-soda process is filtered through a sand water filter, a good amount of silica dissolves in it (forming calcium and magnesium silicates) due to alkaline nature of waters.
Silica sand isn't necessarily washed sand. Silicon dioxide is a chemical compound that is also known as silica. Silica sand is a type of sand that mostly consists of tiny granules of quartz. Quartz itself comes in many varieties, according to its color and microstructure. Silica sand also consists of other fine particles of rock and mineral.

The production of these specialist silica sands for application in glass manufacturing requires specialist screening and classification equipment from CDE. This complex process will first involve a detailed analysis of your feed material both in terms of the particle size distribution (PSD) and the chemical properties of your silica sand.
The production of sand fillers is simple because it includes, at most, only washing and classification into grades differing in grain size. Because sand has a negligible degree of porosity, it has an extremely low specific surface area in the range from 40 to 160 cm 2 /g. The material usually contains more than 99.7% SiO 2, with absorbed water being at a negligible …
