Low-iron bauxites of Vezhayu-Vorykvinsk deposit

Abstract

In our and other countries the share of high-alumina refractories in the total production of aluminosilicate ones has a regular tendency toward an increase.In connection with this broadening of the production of high-alumina refractories on the basis of natural raw material, particularly bauxites, becomes more important, especially as the result of the shortage and comparatively high cost of commercial alumina, which at present is used by domestic industry for a large portion of high-alumina production.

“…The development is hampered by the distance from the railway (about 150 km from the Ukhta station). The deposit has been surveyed by the Ukhtinskaya expedition and some samples have been investigated at the St. Petersburg Institute of Refractories (SPIR) [5].…”
