Investigations of Feldspar-Quartz Raw Materials After Firing:
Different techniques (chemical analysis, X-ray diffraction, Mössbauer spectroscopy, UV-Vis-NIR spectrophotometry and chromaticity measurements) were used to study the color variation of feldspathic raw materials after firing at 1200 °C. Two varieties of feldspar-quartz grits (with Na2O or K2O prevalence) doped with synthetic pigments The production process of high-purity quartz requires ore deposit raw materials with high grade, which are usually pegmatite quartz and hydrothermal vein quartz (Platias et al., 2013, Zhang and Chen, 2010a). At present, the global distribution of high-purity quartz raw material deposits is extremely scarce (Larsen et al., 2000).Resource, characteristic, purification and application of quartz

What are the barriers to the purification process of high-purity quartz
The purpose of the pretreatment stage is to preliminarily screen impurities or crush the quartz raw materials to the desired particle size that is conducive to the release of impurities and subsequent processing. Generally, mechanical crushing, electric crushing, optical sorting, ultrasonic crushing, thermal shock crushing and other processingThe brittle nature of quartz contributes to the additional crushing and cracking of the point’s cutting edge. While this type of damage is more frequent in automorphic quartz, a similar pattern can also be seen in xenomorphic quartz.

As has been described in Paper 2 (Aasly et al., 2006), the most important factor for these properties is the geological history of the raw material. To achieve the optimal raw material, the quartzIn this case, a large number of various-grade quartz tailings are generated. Quartz is useless as tailings, however, it also can be an important raw material for making quartz sand which is widely used in high-tech industries and building industry [16, 17]. Besides, the value of the quartz sand is strongly associated with its purity.Effect of impurity content difference between quartz particles
