ArticleAuthorData Sizyakov Viktor Mikhaylovich, Head of Chair, Department of Nonferrous Metallurgy, tel. (812) 328-84-59, kafmetall@mail.ru, Orlov Anatoliy Kirillovich, Associate Professor; Saint-Petersburg State Mining Institute (Technical University) (Russia).
Abstract
The results of a redox alternative of apatite-nepheline ore thermochemical processing method studies at the temperature of 1350-1400 °С are presented. It is shown, that in this case selection of phosphorus, sodium and potassium is realized in the form of oxide compounds, which is much simpler, than P, Na and K sublimate technology in elementary form by the thermochemical method of Prof. O.N. Tikhomirov, where absolute hermetic sealing of gas paths and creation of special complex equipment for the above mentioned sublimates condensation are required.
keywords Apatite-nepheline ore, reduction, oxidation, oxide sublimates, roasting, tubular rotary kiln, bath smelting, Vanukov furnace.
