It is usually a combination of minerals in the iron group: Hematite, Fe3o3, with a specific gravity of 5.26, an iron mineral that is non-magnetic and Magnetite, Fe3o4, with a specific gravity of 5.20, is magnetic.

Magnetite can be found widely distributed across the world, primarily as large-scale deposits, in igneous and metamorphic rock, in fossils via a biomineralisation process and also in black sand. In addition, Fe 3 O 4 has been found to be deposited in mammalian tissues, including the human brain, also via a biomineralisation process (1).

We Process Black Sands. Due to the heavy iron content of black sands, most processors, smelters and refineries are unable to process them. We have a unique chemistry that allows us to aggressively process precious metals at 20 mesh and below in less than one hour, so we can effectively leach black sands without dissolving the majority of their iron content.
