South africa grade chrome ore
chromite ore for foundry use as a highly
fireproof sharpener for moulds and cores.
Originally from South Africa. 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.

Its properties enable the material to be used in
high duty grey iron and steel foundries as core and
mould making sand. Its high thermal conductivity
gives it good chilling properties, low thermal
expansion gives rise to good dimensional stability.
Its basicity being close to neutral allows the use
of a wide range of resin bonding systems and
inorganic binders, it has a high refractoriness and
a broad sieve distribution.
In steel production, Chromite Sand is used as well
filler for protection of the sliding gate in large
steel holding ladles.
When ground to a fine flour, Chromite Sand is used
for the production of green glass beverage
containers.
