Quality is built through the whole process.
A connected production and inspection system helps control impurity, particle size and batch consistency from raw mineral to finished quartz.
A disciplined production sequence.
The exact process route depends on the starting material and target specification. Chemical treatment is conducted only within controlled industrial systems and safety protocols.
- 01
Crush selected quartz into a controlled feed
- 02
Wash and separate targeted impurities
- 03
Apply controlled acid purification
- 04
Rinse to remove treatment residues
- 05
Air-dry the prepared material
- 06
Calcine under defined conditions
- 07
Complete secondary purification where required
- 08
Filter the treated material
- 09
Grind to the target range
- 10
Filter residual solution
- 11
Water-quench the material
- 12
Rinse with deionized water
- 13
Dry, grade and inspect the finished quartz
