Quartz sand purification process
Anyone who knows <a href="https://www.prominertech.com/ten-uses-and-purification-processes-of-quartz-sand/">quartz sand</a> knows that quartz sand is widely used and is a non-metallic mineral raw material. The purification of quartz sand is difficult. Quartz sand mainly contains some other impurity minerals, including iron-containing impurity minerals: goethite, hematite, limonite, ilmenite, pyrrhotite, tourmaline, amphibole, biotite, etc. The presence of these impurities greatly reduces the use value of quartz sand, so it is very important to remove iron from quartz sand.
In recent years, the research of <a href="https://www.prominertech.com/ten-uses-and-purification-processes-of-quartz-sand/">quartz sand purification and deep processing technology</a> mainly focuses on mineral processing and purification (physical method, chemical method, biological method and combined purification method), silicon powder processing (ultrafine grinding, spheroidization) and surface modification.
