The specific gravity of foundry chromite sand
The specific gravity of natural chromite ore is generally between 4.0 and 4.8 g/cm³. The specific gravity of foundry chromite sand is higher, and the value of 46% chromite sand is higher than 4.5 g/cm³.
The specific gravity of chromite sand is affected by many factors, and the content of chromium oxide, the type and content of impurities have a greater impact on it. When the chromium content is high, the specific gravity will be relatively larger; if there are more impurities with a smaller density, the specific gravity may be reduced. The chromite ore in the South African mining area is of excellent quality, with different grades of 44-45% and 46% chromium content. The higher the chromium content, the higher the specific gravity. Therefore, the specific gravity is one of references for the quality of foundry grade chromite sand.
