Foundry chromite sand with 46% Cr2O3

Chromite sand is used as a highly fireproof sharpener for moulds and cores. Originally from South Africa (SAMANCOR). The sand is produced by crushing chrome ore and its washing in spiral concentrators, subsequent drying, dust cleaning, screening and sorting as per grain size.
