Geology of the Old Hickory Heavy Mineral Sand Deposit ...

The bulk of the older deposit is a clayey sand with 10-30 wt % heavy mineral. In pockets, heavy mineral grades can get quite high (up to 80%). These pockets are often located adjacent to the flanks of buried ridges of saprolitic bedrock. The sand is dominantly clayey quartz sand and locally white kaolinitic pseudomorphs after feldspar are common.

Mining minerals from sand

Layers of dark sand, rich in heavy minerals, can be mined for the heavy minerals they contain. For example, the DuPont Corporation mines heavy mineral sand from the Trail Ridge sand deposit in northern Florida. The mineral ilmenite is used as a source of titanium dioxide (TiO2), which is used to make white plastic and paints more opaque.
