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.
