Summary

The quality control of ball clay products can be broken down into four steps: drilling, mine sampling, blending, and final product testing. Drilling enables the generation of detailed mine maps and plans that aid in mining individual clays in a controlled fashion. Mine sampling is performed as the clay is being mined as a second check on the mining process. Blending helps to dampen small-scale variations inherent to individual clays. Final product testing is performed while the clay is being processed and guards against out-of-spec material being shipped. Computerized mine planning is central to the quality control process. Three-dimensional models of each deposit are generated. Tools such as volume calculations, cross-sections, and isopach (layer thickness) maps are extracted from this model to guide the mining and stockpiling process.
