Removal of iron and arsenic (III) from drinking water ...

 · Iron oxide-coated sand was able to remove iron from contaminated water compared to uncoated sand, as the oxidation of soluble iron (Fe 2+) to insoluble (Fe 3+) takes place at the surface of iron oxide-coated sand and gets precipitated. Iron removal efficiency was higher when limestone was added to coated sand.

To Choose the Right Sand Additive, Understand Composition ...

 · Iron oxides have been used for many years and are typically some form of red iron oxide, black iron oxide, or sometimes a blend. They act as a flux to promote softening of the sand, which can absorb more thermal stress before a crack in the core/mold occurs. Being oxygen-rich, iron oxides also can tie up some gasses during the casting process.
