A Novel Process for Production of High Purity Zirconium ...

2021-9-17  Zircon, a silicate of zirconium (ZrSiO 4), is a source of various zirconium compounds and belongs neo silicate family.It is an essential component of our modern world due to its use in countless everyday products. Zircon, like other natural minerals, is also mined from earth's crust and is available in a minor concentration in heavy mineral sands mostly in beach sands in many parts of the world.

Economic analysis of thorium extraction from monazite ...

2019-4-1  Thorium (232 Th) is four times more abundant than uranium in nature and has become a new important source of energy in the future.This is due to the ability of thorium to undergo the bombardment of neutron to produce uranium-233 (233 U).The aim of this study is to investigate the production cost of thorium oxide (ThO 2) resulted from the thorium extraction process.

Monazite Sands - an overview ScienceDirect Topics

Thorium is produced commercially from monazite sands. After mining, the monazite sands are concentrated magnetically and then treated with either hot, concentrated sulfuric acid or hot, concentrated sodium hydroxide. The acid treatment dissolves the thorium phosphate present, while the basic process converts the phosphates to insoluble hydroxides.

Uranium-preextraction in zirconium/hafnium separations

This is an improvement to a process for making zirconium metal from uranium-containing zircon ore. The process being improved is of the type which utilizes a fluidized bed carbochlorination process of the zircon ore in which uranium chloride is volatilized at the ore chlorinator temperature and follows as an impurity in the zirconium-hafnium tetrachloride stream, and in which removal of iron ...
