AFS45-50 chromite foundry sand from South Africa
Description of chromite foundry sand:
Chromite foundry sand is a natural mineral that contains mostly oxides of chromium and iron. It is a byproduct of ferrochrome and is primarily used in foundry and glassmaking applications. Chromite foundry sand is used as a foundation to repel mold and mildew. It’s from South Africa. Sand is produced by crushing the chromium minerals, washing, drying, dust removal, screening and grain size separation in rotating areas.
