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 customer now blends the reclaimed chromite with new chromite at a ratio of 50/50 and uses on the pattern face as chill sand as well as in the cores.
Read Moremore easily stripped from round-grain sands than from the angular sand grains. However, the scrubbing and grinding inherent in recla-mation tend to round off the sharper types of sands such as angular silica, olivine and chromite. The newly created, less angular grains have a reduced surface area that requires less binder. Technical Article | 02

Chromite Mining Process 2 Processing Chromite Ore extracted from the mine with a grade of 40% chromium oxide or greater is suitable for processing directly in the off-site ferrochrome production facility. Ore with a lower grade must be processed to increase its chromite content.
Read MoreChromite 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.
