In the process of magmatic intrusion evolution, due to the change of temperature, pressure and other conditions, the hydrothermal solution rich in SiO2 is differentiated and penetrated into the wall rock metamorphic rock series along the bedding and fracture, or intruded along the contact fracture zone of the early magmatic rock, forming vein like quartzite ore body.

Types of quartz: powder quartz, green quartz, white quartz, yellow quartz.

Quartz raw materials are classified into ordinary quartz sand, refined quartz sand, high purity quartz sand, fused quartz sand and silica powder.
