Approaches to Recover Zircon Sand from Beach Alluvial ...At present, recovery of zircon from beach sand and red sediments of badlands topography is a priority due to high demand of zircon for industrial applications.
RECOVERY OF ZIRCONIA FROM ZIRCON SANDSavoid recombination or to reduce it to minimum levels, the mixture must be quenched rapidly. As a result, it produces crystals of zirconium oxide in amorphous silica. Further leaching with sulphuric acid is necessary to produce a zirconium sulphate solution and insoluble silica [12]. For leaching, sodium hydroxide can also be used.
Zircon sand prices up sharply in H2 2017--Asian MetalIn addition, overseas major zircon miners are constantly reducing or halting production, resulting in gradual decline for the supply in the overall market. Thus, we think that the tight supply for zircon sand will last for some time in the Chinese market. Iluka, RBM of Rio Tinto and Tronox are major suppliers for zircon sand in the world.

Zircon - WikipediaZircon (/ ˈ z ɜːr k ɒ n / or / ˈ z ɜːr k ən /) is a mineral belonging to the group of nesosilicates. Its chemical name is zirconium silicate, and its corresponding chemical formula is Zr SiO 4. A common empirical formula showing some of the range of substitution in zircon is (Zr 1–y, REE y)(SiO 4) 1–x (OH) 4x–y.
