recovery of zirconia from zircon sands

recovery of zirconia from zircon sands the use of zirconia in many fields has grown enormously. the major and cheapest source of zirconia is zircon sand. despite this the decomposition of zircon is not easy to achieve due to its stability. considering the structure of zircon which is extensively discussed in the literature [3.

leaching of metals with chemolithotrophic and heterotrophic organic acids producing microorganisms has been investigated with zircon from the baltic shield containing 0.7% rare earth elements and 1.67% hafnium. when zircon is leached with strains of thiobacillus ferrooxidans about 80% of the rare earth elements hf th and u can be recovered.

recent pb loss in zircon: a natural or laboratory-induced

pidgeon et al. (1973) demonstrated that pb can be removed from zircon by acid leaching in a series of laboratory-controlled experiments at temperatures down to 350r c. the effectiveness of this mechanism was st~h that it would undoubtedly continue to operate at considerably lower temperatures especially over longer time intervals.
