contamination effect of chromite sand in silica sand
Aug 21, 2013· As can be seen from the above XRF results, the seperated chromite sand contains less than 0.5% silica contamination and therefore is perfect for re-use at the mixer. 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.
