Abstract

Способ получения циркония, включающий электролиз расплава электролита, содержащего фторцирконат калия, хлорид калия, фторид калия при концентрации хлора 8,0 - 13,0 мас.% и начальной катодной плотности тока 2,0 - 3,5 А/см, и последующее выделение циркония гидрометаллургическим методом, отличающийся тем, что, с целью снижения удельного выхода фреонов, повышения степени разделения циркония и гафния при переходе его из исходной соли в катодный металл, повышения выхода по току порошка циркония и извлечения циркония из исходной соли, электролиз осуществляют с введением в расплав хлорида натрия в количестве, обеспечивающем содержание натрия в электролите 2 - 4 мас.%, и при поддержании содержания циркония в электролите 3,0 - 5,0 мас.%.A method of producing zirconium, including electrolysis of a molten electrolyte containing potassium fluorocirconate, potassium chloride, potassium fluoride at a chlorine concentration of 8.0 - 13.0 wt.% And an initial cathode current density of 2.0 - 3.5 A / cm, and subsequent release zirconium hydrometallurgical method, characterized in that, in order to reduce the specific yield of freons, increase the degree of separation of zirconium and hafnium when it is transferred from the original salt to the cathode metal, increase the current efficiency of the zirconium powder and extract zirconium from the original salt Melt with the introduction into the melt of sodium chloride in an amount that provides the sodium content in the electrolyte 2 to 4 wt.%, and while maintaining the zirconium content in the electrolyte 3.0 to 5.0 wt.%.
