Natural Garnet Sand

Updated: Nov 17, 2021

Garnet Sand is is known for its hardness, Which makes it popular in many industrial uses. We are one of the largest Manufacturer & Exporter of Garnet Sand from India.


About Garnet-

Garnet sand is that the collective name for a gaggle of minerals which crystalize during a cubic system with different chemical composition. The principal members of the Garnet group are Almandine (Fe-Al), Pyrope (Mg-Al), Spessartite (Mn-Al), Grossularite (Ca-Al), Andradite (Ca-Fe), and Uvarovite (Ca-Cr). Almandine is harder amongst all varieties and is usually used for abrasive purposes. Garnet is solid & hard with sharp angular chisel-edged fracture, including small amounts of free silica, and exhibits high resistance to physical and chemical attacks. it’s used both as a semi-precious stone and as an abrasive. The hardness of garnet varies from 6.5 to 7.5 on the Mohs’ scale. this enables it to be used as an efficient abrasive.


Garnet Sand may be a high performance, maintenance grade abrasive that delivers efficient and cost-effective blast cleaning for surfaces. it’s utilized in dry blast cleaning, wet blast cleaning, and waterjet cutting. Known for its hardness and durability, it’s a chemically inert, natural mineral. Where conditions allow recycling the fabric is often used as a less expensive alternative to aluminum oxide, Chilled Iron, or Steel Grit. the product is dominantly garnet (almandine variety) which may be a Non-Hazardous substance. Traces of dust within the unused product are from carbonate which is additionally Non-Hazardous.


What is Hardness of Garnet?

Garnet is a naturally inert mineral that is a sharp, angular, 12-sided crystal (officially a rhombic dodecahedron), with a hardness of between 7.5 and 8.5 on the Mohs scale, It is also known that Garnet is the second hardest mineral in the world and the first hardest mineral is diamond (diamonds, which serve as the benchmark for hardness, rank as a 10).


Physical Properties Of Garnet Sand:

  • High specific gravity: 3.8 – 4.2

  • Weight per cubic foot: 120 – 151 lbs

  • MOH hardness scale: 7.6 – 8.0

  • Acid solubility: <1%

  • Cleanliness: Low dust

  • Durability: Because of its hardness, high specific gravity, and the pounds per cubic foot, garnet sand, when installed correctly, stays in its own layer holding down the layers underneath during backwash.
