Quartz sand kaolin ore is a mineral composed of a mixture of quartz sand and kaolin. The formation of quartz sand kaolin ore is closely related to the geological environment and climatic conditions of the region. Quartz sand kaolin deposit belongs to the weathering residual type kaolin deposit, which is formed by long-term weathering, leaching, transportation, and accumulation of primary silicate rocks such as granite and gneiss. The main components of quartz sand kaolin ore are quartz and kaolin, as well as small amounts of minerals such as mica, feldspar, tourmaline, rutile, zircon, and clay. The characteristic of quartz sand kaolin ore is high sand content, generally above 50%, and even above 80%, so it is also known as sandy kaolin ore. The sand of quartz sand kaolin ore is mainly composed of quartz, which is a mineral with high hardness, wear resistance, acid and alkali resistance, and high temperature resistance, and has good optical and electrical properties. The kaolin of quartz sand kaolin mine is mainly composed of kaolin, which is a mineral with low softness, strong plasticity, and good fire resistance, and has good adsorption and chemical stability. The sand and kaolin of quartz sand kaolin mine complement each other, forming a composite material with multiple excellent properties.
