Overall, the Hongji heavy mineral processing engineers believe that research and development of highpurity quartz is divided into three steps: experimental research on ore beneficiation process mineralogy study, and purification of quartz raw ore. The crushing processing conditions are different depending on the different processes and equipment, such as jaw crusher, cone crusher, roll crusher, screen .
rejects. Large quantities of tailings with the high content of high purity quartz are typical of all stages of pretreatment and preconcentration. It is necessary to reduce loss of high purity quartz at early processing stages by opti mizing circuit s of grinding and screening as well as by using the most efficient methods of sorting of
It is the high purity of the IOTA product that enables these parts to withstand the chemical and temperature extremes of wafer processing. Sibelco's high purity quartz portfolio for semiconductor grade applications includes IOTA 4, IOTA 6, IOTA 6SV, IOTA 8 and IOTA STDSV. The low alkali content of these products results in fused quartz with high viscosity.

silicon(monosilicon) from silicon metal. In order to produce the highquality semiconductor plates, polysilicon is placed into a quartz crucible heated to a high temperature, and a monosilicon is drawn out of the melted silicon. The fused quartz is one of the few materials that combine high purity and heat resistance required for the process.
Quartz can be found in sand deposits, high purity crystal deposits and is found to some degree as a minor component in most mineral formations. Quartz is highly abrasive with a Mohs hardness value of It is also very chemical resistant and durable. Ground quartz is used as fillers in the paint, adhesives and plastic industries.
