Process for purifying silica sand Materias Primas

A process of purifying silica sand comprises grinding sandstone, washing and desliming the ground sandstone to remove the major part of the claytype binder, attritionscrubbing the deslimed sand particles to release further amounts of binder therefrom, washing and desliming to remove said binder, drying and heating the sand particles, treating the hot sand with sulfuric acid to convert the iron Applying color sorter to quartz sand purification in sand washing plant In the raw quartz sand, the pure quartz sand is white or milky white, and the color of iron bearing impurities or gangue minerals is yellowish, light yellow or light brown and gray The color difference between quartz sand and iron bearing impurities or gangue minerals is Applying color sorter to silica sand purificationSinonine Now we summarize the following common quartz sand purification methods 1Washing, grading and desliming of quartz sand The grade of SiO2 in quartz decreases with the decrease of quartz particle size, while the content of impurity minerals such as iron and aluminum will increaseHow to purify quartz sand?Sinonine Silica sand
