Strict Quality Control & Ocean-Ready Packaging
At Osgood Minerals, product consistency and safe arrival are non-negotiable. Situated in Lingshou’s mineral processing hub, we enforce rigid multi-stage batch testing and marine-grade moisture barrier packaging to ensure your minerals arrive dry, pure, and ready for immediate manufacturing.
1. Three-Tier Quality Assurance (QA) Process
Step 1: Raw Ore Grading
Every batch of incoming raw muscovite, vermiculite, and perlite is pre-screened for heavy impurities, baseline whiteness, and thermal expansion ratio before entering kilns or mills.
Step 2: In-Process Lab Testing
Automated laser particle size analysis (Malvern), dry/wet sieving tests for residue, and thermal testing (LOI < 0.5% verification for calcined grades).
Step 3: Pre-Shipment Inspection (PSI)
Retention samples are kept for 24 months. Standard Certificate of Analysis (COA) issued per container; third-party inspections (SGS, CCIC) fully welcomed.
