Zirconia enrichment in zircon sand by selective fungus

One of the important routes for the production of zirconia is by chemical treatment and removal of silica from zircon sand (ZrSixOy). We present here a completely green chemistry approach toward enrichment of zirconia in zircon sand; this is based on the reaction of the fungus Fusarium oxysporum with zircon sand by a process of selective extracellular bioleaching of silica nanoparticles.

Sand casting

Zircon sand is a compound of approximately two-thirds zirconium oxide (Zr 2 O) and one-third silica. It has the highest fusion point of all the base sands at 2,600 C (4,710 F), a very low thermal expansion, and a high thermal conductivity. Because of these good properties it is commonly used when casting alloy steels and other expensive alloys.
