Garnet is the name of a group of iron aluminum silicate minerals. Only a few types of garnets have gemstone quality, and most garnets are used as industrial abrasives for grinding and polishing.

The biggest use of garnet is as abrasive.

Almandite is the main industrial abrasive because of its high specific gravity and hardness. Spessartite and Pyrope are also used as industrial garnet abrasives.

Garnet mining

Garnets are relatively durable minerals. They are often concentrated in soils and sediments that form when garnet-containing rocks are weathered and eroded. These alluvial garnets are the mining target as they are easy to mine by mechanical processing.

For example, at the Emerald Creek mine in Idaho, the garnet mineral is recovered from stream gravels from slots cut by backhoes.

Garnet processing plant

By processing into particles, garnet can be used as industrial abrasives.

    Embedded in the rock, which means that garnet and its accompanying gangue coexist.
  • Distributed in placer and completely dissociated from the sand.

1. How to process garnet rock mine?

Garnet rock mine has a low dissociation degree of monomers. Therefore, the combined beneficiation methods (magnetic separation, gravity separation, and flotation separation) are required.

Note that gravity separation is used for coarse-grained garnets. Magnetic separation is used for separating medium and fine-grained garnets. Flotation separation produces the highest-grade garnets.

    • First, the large garnet rock is crushed by a jaw crusher to reduce mineral particle size. Then, it enters an impact crusher for fine crushing.

    Crusher

    The finely crushed garnet is screened by a circular vibrating screen. If the size of the material meets the requirements, it will enter the grinding process.

    Crusher

    Garnet is further ground using a ball mill until the monomers dissociated. The output size can reach 0.074 mm or 325 mesh.
