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 economic deposits of chromite First chromite is one of the more weathering resistant minerals of peridotite That causes it to be concentrated in residual soils that form in the weathering
