Zirconium Wikipedia

Zirconium metal was first obtained in an impure form in 1824 by Berzelius by heating a mixture of potassium and potassium zirconium fluoride in an iron tube. [8] The crystal bar process (also known as the Iodide Process ), discovered by Anton Eduard van Arkel and Jan Hendrik de Boer in 1925, was the first industrial process for the commercial production of metallic zirconium.

New Solvent Extraction Process for Zirconium and Hafnium

The authors' company developed a new solvent extraction process for zirconium and hafnium separation, and started production of zirconium sponge by this new process in September 1979. The process utilizes selective extraction of zirconium oxysulfate using high-molecular alkyl amine, and has the following advantages: 1. This extraction system has a separation factor as high as 10 to 20 for

Method of separation of zirconium and hafnium

The process is carried out in a cascade of centrifugal extractors. Weight of extract zircon from reextract hafnium depends on to the concentrations therein of nitric acid: the higher the acidity of the solution, the more zirconium is extracted by the extractant. However, when the acidity of more than 340 g/l in the extract begins to move and hafnium. The best is the concentration of nitric acid in reextract hafnium
