Silica sand is the primary ingredient, making up about 65-75% of the total weight. Soda ash is added to the mix, along with other materials, to reduce the melting point of the glass. Limestone is used to control the viscosity of the molten glass. Silica sand is the primary source of silica dioxide, or SiO2.

At present, the common silica sand processing plant is to remove the mineral impurities in the silica sand by scrubbing and desliming, magnetic separation, chute gravity separation, flotation, pickling or several combined methods to obtain high purity silica sand with particle size and impurity content that meet the requirements.
The quartz is then heated at high temperatures, up to 1800 °C, and undergoes a reaction with Na 2 CO 3 to produce Na 2 O.SiO 2 and CO 2 following reaction 2.
no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.
