Claims (2)

1. Способ переработки бадделеита, включающий растворение во фтористоводородной кислоте с получением фтористокислого раствора циркония, перевод его в твердый сульфат циркония сульфатизацией с последующим получением гидроксида циркония и его прокаливанием до диоксида циркония, отличающийся тем, что растворение ведут в кипящей фтористоводородной кислоте с одновременной конденсацией ее паров и возвратом конденсата на растворение бадделеита, сульфатизацию ведут при подаче фтористокислого раствора циркония в концентрированную серную кислоту при ее нагреве до 200 - 250°С с конденсацией паров фтористоводородной кислоты и возвратом ее на растворение бадделеита.1. A method of processing baddeleyite, including dissolving in hydrofluoric acid to obtain a zirconium fluoride solution, converting it to solid zirconium sulfate by sulfatization followed by calcining zirconium hydroxide and calcining it to zirconium dioxide, characterized in that the dissolution is carried out in boiling hydrofluoric acid with vapors and return of condensate to the dissolution of baddeleyite, sulfatization is carried out by feeding a zirconium fluoride solution in concentrated sulfuric slot when it is heated to 200 - 250 ° C with hydrofluoric acid vapor condensation and returning it to the dissolution baddeleyite. 2. Способ по п. 1, отличающийся тем, что получение гидроксида циркония осуществляют путем подачи сульфата циркония в аммиачную воду. 2. The method according to p. 1, characterized in that the production of zirconium hydroxide is carried out by supplying zirconium sulfate in ammonia water.
