Abstract:
This article deals with heavy placer mine to metals and materials, especially preparation of nanomaterials from strategic minerals of placer deposits which are derived from the badlands topography existing along the east coast of India. In the present study, red sediment samples were collected from the badlands and subjected to physical separation processes to recover high-grade individual placer heavy minerals for value-addition, which includes preparation of titanium oxide, titania slag, titanium oxide nanomaterials from comminuated ilmenite mineral as well as preparation of zircon flour, and zirconia nanomaterials from natural zircon mineral.
