Z ircon (ZrSiO 4) is found usually as a constituent in heavy mineral sand assemblages, which include ilmenite, rutile, leucoxene, monazite and garnet in varying proportions. Zircon sand and baddeleyite (an oxide-ZrO 2) are used via their salts to extract zirconium and hafnium. Normally, all zirconium compounds contain between 1.4% and 3% hafnium.
8. Staurolite & Sillimanite –by products of zircon mining. Note 2- India has production of around 44kt and reserves of > 4 million tonnes of sillimanite – Granular sillimanite is obtained from beach sands in Kerala, Odisha and Tamil Nadu as a by-product along with ilmenite, rutile, zircon, garnet, etc. while recovering monazite.
In production of premium grade zircon, rejection of sillimanite from the zircon stream has always been the biggest challenge due to the small specific gravity difference between zircon (4.6) and sillimanite (3.25) and the stringent limit on alumina content, i.e., 0.45% in premium grade zircon. Microscopic images of original zircon in ROM sand and
The production of ilmenite was 351 thousand tonnes in 2019-20 increased by 20% as compared to that in the preceding year. Odisha was the leading producer of ilmenite during the year under review, contrubuting 69% of the total production followed by Kerala (21%) and Tamil Nadu (10%).
