In basis of decomposition of the second raw material, containing rhodium, alloying is fixed from Na2S2O7 with subsequent electrochemical dissolution of rhodium by the alternating current of industrial frequency in sulphuric acid solutions. Degree of extraction of connections of rhodium not below 93 %. Optimize the parameters of obtaining ultrafine zirconium dioxide from domestic raw materials, based on a hydrothermal leaching of alkaline solutions containing a fluorinating agent calcium fluoride - calcium-waste thermal process for obtaining zirconium.The parameters of receipt of ultra dispersion zirconium dioxide are optimized from domestic zirconium raw material. It was found, that the optimum correlation between reagents at the receipt of dioxide of zirconium is :[concentrate]: [CaF2 ]: [NaOH ] = 1:[1,0-1,5]:[5-8] Product Description popup.authors Близнюк Антоніна Вікторівна Буряк Микола Іванович Гур'янова Ірина Олександрівна Забудська Софія Євдокимівна Захарченко Микола Ферорович Козін Валентин Хомович Компаніченко Наталія Михайлівна Литовченко Валентина Данилівна Онищук Софія Федорівна Остапенко Олена Володимірівна Павленко Тамара Володимірівна Рудковська Любов Мартинівна Савчук Руслан Миколайович Счастлівцев Сергій Вікторович Третьякова Ірина Миколаївна Харькова Людмила Борисівна Яремчук Галина Григорівна popup.nrat_date 2020-04-02 Close
