Silica Sand Quartz Sand

Description

Silica sand is a kind of silicate minerals, which is hard and wear-resistant . The main chemical composition of silica sand is SiO2: 99.5%min. The mineral is of good quality and high purity.

Producing process:

Smash--Selecting--Seperate--washing--dry--Precision selecting
