The existence of iron impurities greatly reduces the use value of silica sand and affects the quality of products. For example, in glass production, iron impurities will do great harm to the production and quality of glass, especially to the thermodynamic properties of glass melting process and the transparency of glass products.
The impurities removed from the vein quartz sands were investigated with six complexing agents (citric, oxalic, acetic, humic acid, EDTA and thiourea). So as to optimized the leaching reaction parameters and to reach a high rate of impurities removal, the kinds and concentration of complexing agents, reaction temperature and time were also discussed.
Silicon Dioxide refers to ordinary sand, which is also known as silica or quartz. Silica Sandblasting was a commonly used method of removing impurities from surfaces; this is because sand particles are almost the same size and the edges of the particles are sharp, hence making this type of grit efficient in abrasive blasting.

Through this process, silica becomes a sealant, an adhesive, or a lubricant. For it to become adequate to process food, Silica (SiO2) is reduced to silicon metal by coke in an arc furnace, to produce the Si precursor of the other chemical processes. The chemical process and production is dependent on the use of industrial sand.
Silica sand deposits are most commonly surfacemined in open pit operations, but dredging and underground mining are also employed. Extracted ore undergoes considerable processing to increase the silica content by reducing impurities. It is then dried and sized to produce the optimum particle size distribution for the intended application.
