As a general side effect from the casting process, the chromite sand tends to see most of the heat from the molten metal and so is also naturally thermally reclaimed. The foundry now blends the reclaimed chromite with new chromite at a ratio of 50/50 and uses it on the pattern face as chill sand as well as in the cores.
