At the Pavlodar aluminum plant, high-siliceous bauxite is processed by a sequential method of Bayer sintering. In the near future, it is planned to use bauxites from various deposits characterized by an increased content of carbonates. ...

In the early fifties, the exceptional importance for aluminium metallurgy of a peculiar process of introduction of alkali metals (and certain other substances) into the interlayer space of carbon-graphite materials was established for the first time.

Melts containing titanium and zirconium chlorides are used in the production of refractory metals and their alloys. In particular, the electrolytic process for producing titanium-zirconium powders was investigated. An equimolecular melt of NaCl and KCl salts containing di- and trivalent titanium chlorides and zirconium tetrachloride was used as the electrolyte. The content of dissolved zirconium in the electrolyte did not exceed 0.8%.
