Why Chromite Sand Minerals Technologies Inc.

Silica Sand undergoes an alpha-beta phase transformation at approx 350oC – 650oC. This corresponds to the temperature zone that the mould experiences during cooling. This can lead to expansion defects such as veining or cracking in castings where silica sand moulds are used Chromite has a much lower expansion over the same temperature range.

Hands on advice for successful sand reclamation Castings

Chromite sand is normally used in combination with silica sand to produce surface chill or to promote directional solidification. During the recycling steps of the reclamation process, the chromite and silica become thoroughly blended, unless some separation device is used. The amount of chromite present in the silica system varies.

Chromite Separation Case Study by Omega Foundry

2015-12-18  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.
