Autor: A.E. Kireev, I. V. Loginova, L. I. Chaikin
Publikováno v: Solid State Phenomena. 316:619-624
The main aim of this work is to obtain a compact spherical titanium powder by the metallo-thermic reduction. The feedstock is TiO2 (rutile), and aluminum shavings are used as the reducing metal. In the reduction process granules of titanium powder an

Bauxite residue, known as “red mud,” is a potential raw material for extracting rare-earth elements (REEs). The main REEs (Sc, Y, La, Ce, Nd, Nb, and Sm) from the raw bauxite are concentrated in RM after the Bayer leaching process. The earlier wo

Extraction of Rare-Earth Metals During the Systematic Processing of Diaspore-Boehmite Bauxites
Autor: A. A. Shoppert, L. I. Chaikin, I. V. Loginova
Publikováno v: Metallurgist. 60:198-203
An integrated technology is proposed for processing diaspore-boehmite bauxites and extracting their useful components. It is established that sintering bauxite with a caustic alkali increases the quantities of rare-earth metals that are recovered. Ex
