Chromite Separation Case Study by Omega Foundry Machinery ...

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.

more 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
