Olivine is an inert and non-toxic abrasive mineral having a hardness between 6.5 to 7.0mohs
in nature it is widely used for wet blasting abrasive system also restores aluminum, fiberglass, marbles, and
stone facades, wood and steel. The Olivine Sand acts as a good substitute among other sands for its cost
reduction, easy disposal concern, recycling property, replaces garnet sand and create a high performance
in slurry blast mixture.
