Hands on advice for successful sand reclamation

At elevated temperatures, and in an oxygen containing atmosphere, Fe oxides and chromite sand increase in weight. Because of this increase in weight during the LOI test, standard LOI testing cannot be run on chromite sand or chromite-silica mixtures. This change partially makes up for some of the weight loss because of the binder being burned off.

Meanwhile, performance testing has confirmed all of the expectations for SpheriChrome. Smith noted the material performed differently than the South African chromite that is available now to foundries because of its exceptional roundness. The South African chromite has a much more angular grain structure, due to crushing, he stated.

Chromite: The only mineral ore of chromium metal

Chromite is found in beach sands derived from the weathering of chromite-bearing rocks and laterite soils that developed over peridotite. Beach sand rich in chromite and other heavy minerals is sometimes mined, processed to remove heavy minerals, and returned to the environment. Two facts allow these chromite sands to occasionally contain
