About Quartz Sand products

“MEREN” Quartz Sand

Quartz is the most important sand-forming mineral and occurs in very many sand types but usually not exclusively. In this sand type (which is aptly named quartz sand), quartz is almost the sole component of sand.

“Quartz sand”

Quartz sand is a quartz particle produced by crushing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. The color of quartz sand is milky white, or colorless and translucent, with a Mohs hardness of 7.


Quartz sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter materials and other industries.

Quartz Sand Grade 2

“Quartz sand”

Sand which mainly consist of the quarzt mineral.
The grade of raw quartz sand in the industry is getting lower and lower. To meet the needs of the industry, the grade can be improved through the beneficiation process. There are mainly the following purification methods:

  • Scrubber
  • Magnetic separation
  • Flotation
  • Acid leaching
  • Microbial leaching

It refers to using microorganisms to leach thin film iron or immersion iron on the surface of quartz sand particles. This is a newly developed iron removal technology.
Process flow:

  • stones enter the warehouse
  • rough crushing
  • fine crushing
  • sand making machine
  • sand washing
  • drying
