Black Sand

Black sand can be seen as a layer on top of silica sand in regions with high wave energy, on the flanks of volcanoes, and in areas where most of the source rock is mafic, or dark-colored and poor in silica. It can be composed of a number of different dark minerals, most are iron-rich and heavier than silica sand.

While some beaches are predominantly made of black sand, even other colour beaches can often have deposits of black sand, particularly after storms. Larger waves can sort out sand grains leaving deposits of heavy minerals visible on the surface of erosion scarps.

Black Sand Crushing Operation

Black sand is a combination of a variety of materials such as lead carbonites, hematite and iron. The variations of this dark-colored sand are numerous, so these metallic combinations are referred to as "black sand." Gold, minerals and gemstones are often found in black sand, so miners search for it as a way to find these other items.

To get the valuable miateral, the black sand will be first crushed for liberation. Crushing generally is carried out in oneor two stages, although three-stage crushing may also be performed. Jaw crusher, impact crusher, or gyratory crushers are usually used for initial reduction. Cone crushers are commonly used for secondary crushing. The crushed black sand will be returned to the screening operation for sizing.
