The composition of quartz is the simplest form of silica, with a glassy luster and no cleavage surface, but with shell like fractures. Microcrystalline quartz is called chalcedony, agate, or jasper. Pure quartz is colorless, but appears in different colors due to impurities that often contain transition elements. Quartz is very stable and not easily weathered or transformed into other minerals. According to the degree of SiO2 crystallization, it can be divided into phanerocrystalline single crystal quartz and polycrystalline Quartzite jade. Gloss: Glass luster. Color: None, white, with a hint of gray, yellow to orange yellow, purple, deep purple, pink, grayish brown, brown, and black. Stripes: White. Specific gravity: 2.65~2.66. Category: Metamorphic rock, metamorphosed from sandstone.

Formation process

In the process of magma intrusion and evolution, due to the change of temperature, pressure and other conditions, the magma differentiates into SiO2 rich hydrothermal solution, penetrates into the surrounding rock Metamorphic rock series along bedding and fractures, or intrudes along the contact fracture zone of earlier magmatic rock, forming vein Quartzite orebody.

Substance classification

Quartz types: pink quartz, green quartz, white quartz, and yellow quartz.

Quartz raw materials can be divided into ordinary quartz sand, refined quartz sand, high-purity quartz sand, fused silica sand, and silica micropowder.
