Garnet is one of the hardest and the heaviest minerals in the world.
It is formed at convergent plate boundaries when sedimentary rocks are acted upon by metamorphism. This heat and pressure breaks chemical bonds and causes minerals to recrystallize as tiny grains and enlarge slowly over time as garnet as metamorphism progresses. The most commonly encountered minerals in the garnet group include almandine, pyrope, spessartine, andradite, grossular, and uvarovite.
The inertness, hardness and resistance to degradation makes a superior abrasive, ideal for most industrial applications particularly in energy, infrastructure and resource sectors. With the purity of 99%, Garnet is the most accepted mineral in Sand Blasting, Water Jet Cutting, Water Filtration, Surface preparation, Abrasive Powders etc.
• Lower Abrasive Consumption thus giving rise to high productivity
• Recyclability upto 5-7 times reducing industrial waste
• Significantly low dust emissions reducing clean up costs
• Gives Superior Surface Quality
• Cost effective over other abrasives
• Sand Blasting : The fast cutting action and speed of garnet makes it suitable for sand blasting and thus an alternative to silica sand. The most recommended sizes are # 20/40 and #30/60. Its unique size and particle distribution makes it popular in oil companies, petrochemical tankworks, bridges, rail tanks, offshore platforms, pipelines, heavy equipment repair, tarnish cleaning, industrial parts cleaning and ship building companies.
• Water Jet Cutting : Garnet #60, #80 and #120 are known for water-jet cutting applications for cutting high strength steel, automotive glass, plastic laminates, steel bridge decking, artificial stones, non-ferrous metals, granite and marble which is quite popular in Europe owing to its high productivity and superior edge quality.
• Water Filtration : Due to its inertness and relatively high specific gravity, it is often used as filter media to to filter out contaminant particles as small as a few microns in diameter. Its high hardness reduces bed expansion and particle abrasion during backflushing.
• Abrasive Papers : Garnet is an excellet abrasive, especially for sanding wood and also for coating and polishing other surfaces. It is used for polishing glass face plates of televisions, computer monitors sand for artistic engraving or matting of surfaces such as glass, marble, granite, etc.
• Jewellery : Garnet has been used as a gemstone for over 5000 years and continues as a popular gemstone even today. Red almandine is the red garnet most often found in jewelry because it is abundant and inexpensive.
