Quality-assured abrasives
Quality assurance and control
Rigorous QA and QC measures are fundamental to our garnet mining and production. Over 40 years we have constantly improved our production, monitoring, and testing methods, as well as the technologies embedded in our operations. This guarantees GMA Garnet's consistent performance in every batch.
Sampling and testing
Heavy mineral concentrate samples occur every two hours before garnet leaves the mine, at intervals during processing, and again as a final product, so only garnet meeting strict standards gets delivered to our customers. These tests ensure that GMA Garnet™ achieves the highest industry and quality standards.
International quality certification
Our production process — from mining to processing and administration — is certified under international quality standards:
- ISO 9001:2015 - Quality Management Systems
- ISO 14001:2015 - Environmental Management Systems
- ISO 45001:2018 - Occupational Health & Safety Management Systems
