Advanced mining, processing, and refining operations
GMA’s garnet deposits have a unique geological history resulting in exceptionally hard, tough, dense almandine garnet ideal for industrial abrasives.
Our Australian and South African deposits contain alluvial garnet optimally shaped for high productivity and surface quality in blasting and waterjet cutting applications. In the United States, our deposit is of hard rock garnet, which gets crushed to produce coarser grains for more effective cutting of thicker, harder coatings and materials.
For 40 years, we have led innovation in industrial garnet. By developing our own mining processes and technologies, including unique mineral separation techniques, wet plant processing, and group grade separation, GMA continues to push boundaries in product performance.
Quality assurance
Quality control measures are fundamental to all aspects of GMA’s garnet mining and production. Over 40 years, we developed advanced production monitoring methods and technologies as part of our commitment to excellence.
Only the highest quality garnet that meets strict internal and industry specifications, including ISO standards, is delivered to our customers.
