What is the silicasandmanufacturingprocess or silicasandextraction? Silica sand is a very important industrial raw material and is widely used in glass, refractory, metallurgy, and other industries. Generally, the main mineral of natural silica sand is quartz, and other impurity minerals are often accompanied. The mixing of these impurities reduces the value of silica sand and affects the quality of the product.
Generally, the natural quartz sandstone ore is broken into small pieces by jaw crusher, then the grinding equipment is used for wet grinding, and the small quartz ore is ground into finer quartz sand. Then, the grinding product enters the grading operation, and the quartz sand which meets the particle size requirement can be used as the raw material quartz sand for the next stepping of removing and purifying quartz sand, and the coarse grain is returned to the grinding equipment for further grinding.
With the help of the mechanical force of the scrubber and the grinding force between the sand particles, the thin film iron and mud impurity minerals on the surface of the quartz sand are removed, and the unformed mineral aggregates are further scrubbed, and then the grading operation is carried out to further purify the silica sand.
If there are many kinds of mica minerals in raw materials, It is impossible to remove impurities completely if only a spiral chute is used. At this time, the flotation process can be used to remove these impurity minerals.
If the finished product sand is reddish after the removal and selection operation, it means that the iron and titanium content in the product does not meet the requirements of product quality. At this time, the pickling method can be used. First, wash off the powder and impurities with water, and then use soak in acid, then rinse again with water, and finally dry or air dry.
The above is the silica sand extraction process. Impurity removal is carried out when the impurity minerals and quartzes minerals reach the state of monomer dissociation, almost all impurity minerals in the raw materials are removed, the purity of the quartz sand is greatly improved, and the corresponding silica sand concentrate products are obtained.
Fuji Silysia Chemical Ltd. (FSC) is a manufacturer of synthetic amorphous silica, a formation of silicon dioxide that is tasteless, colorless and odorless. The term silica-gel is derived from the manufacturing method, sol-gel, to produce this material. Two raw materials, sodium silicate and mineral acid, are used in a wet process to create a reaction in generating monomeric silicic acid. These monomers polymerize to generate primary silica particles, referred to as silica sol. These particles then aggregate to form a three-dimensional structure in a gel state maintaining a low refractive index of 1.46. During this process, growth conditions affecting the primary particles (sizes 3-30nm) are controlled to modify physical properties such as surface area, pore diameter and pore volume.
The SEM image shows the polymerization of the primary particles making the structure mechanically strong. The three-dimensional network creates the internal and external surface area and porosity of the silica-gel. These physical properties can be adjusted by attenuating production conditions, making it possible to adapt each grade produced to various applications. For example, as a matting agent in paint and coating systems, as an anti-block agent in plastics, as an absorption and separation agent in chromatography or as a catalyst support. A few of the brands under which FSC markets silica-gel include SYLYSIA, CARiACT and SYLOMASK.
Silica-gel differs from precipitated and fumed silica. Precipitated silica is manufactured by precipitation method. Sodium silicate and mineral acid react under high temperature in alkaline conditions, during which the primary particle is grown rapidly to a diameter of approximately 100nm. It is precipitated then aggregated by flocculation into the alkaline liquid. In contrast to silica-gel, this method of production creates negligible internal surface area, devoid of strong primary particle polymerization. Under high shear, precipitated silica can break down, which may affect viscosity and reduce matting performance. The SEM image of precipitated silica clearly shows the physical differences.
Fumed silica is manufactured via a dry process of combustion hydrolysis in the gas state. This method generally requires an investment in high-energy mechanics. The primary particles consist of nano-size flakes. Fumed silica, structurally, has no gap among particles and is weakly agglomerated together with minimal internal surface area. Fumed silica is traditionally utilized for rheological purposes.
Due to the manufacturing process, fumed and silica-gel generally have the highest purity. All three forms of silica have a low refractive index similar to glass. Many of the attributes are specific to the product grade; e.g. particle size, oil absorption and surface area. Silica-gel is the only silica to have internal porosity.
