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.

Application:
The chromite sand is compatible with all chemical processes for molds and cores. Currently large amounts of chromite sand are used in the foundry industry for the manufacture of molds and cores.
Chromite Sand is applicable to all types of steels and very appropriate for parts of chrome, chrome-nickel, manganese steel.
