Scientists are working with bauxite samples.

Quality control of bauxite.

The ratio of aluminum and alumina oxides to silica is an important indicator of the quality of bauxite.

The shlif of Tikhvin bauxite.

Turgay bauxite.

Bauxite plume of the northern Urals.

Pelitomorphic Ural bauxites.

Samples of bauxite.

The oldest bauxites began to form on earth more than 500 million years ago.

A cartoon explaining the formation of bauxite at this time.

Laterite bauxite.

The most famous laterite bauxites are West African.

Continuation of the cartoon.

In the Soviet Union, Belgorod bauxites were formed in this way, Vysokopolsky in Ukraine and on the Middle Timan.

A cartoon explaining the further process of bauxite formation.

Tikhvin bauxites.

North-Voronezh bauxites.

South Pacific sedimentary bauxites.

Bauxite mining at the oldest Tikhvin bauxite quarry.

In the Tikhvin bauxites, most of the alumina is in the form of boehmite.

A cartoon explaining the appearance of Turgai-type bauxites.

Meso-Cenozoic deposits of Turgai type.

Bauxites from these deposits have a bean structure.

Bauxites of oolitic structure are found in these deposits.

Diasporic structures of the South Ural deposits.

A map with estimated bauxite deposits in Siberia.

Panorama of places with bauxite deposits in the Urals.

Types of bauxite of industrial importance.

Geologists are following the route.

Geologists on the rocks of the Ural Mountains.

Aerogammaspectrometry makes it possible to detect sedimentary deposits of bauxite enriched with radioactive elements.

The geologist on board the aircraft is conducting observations.

Seismic methods are used in the search for deep-lying bauxites.

The obtained seismograms make it possible to identify areas promising for bauxite.

The method of vertical electric sounding is used to search for Turgai-type bauxites.

A cartoon explaining this method.

Geologists on the bus take readings.

Two-plane electrical reconnaissance is used to survey large areas.

The geologist analyzes the data obtained.

Magnetic exploration allows you to record deposits of a magnetic variety of bauxite.

Modern magnetometers detect even weak magnetic anomalies.

The data is recorded on a paper tape and simultaneously prepared for input into a computer.

Entering information into the computer.

A computer with the help of a cartographic system creates a map of magnetic anomalies.

Analysis of the received data.

In promising areas, research is being conducted with the help of drilling rigs.

A geologist studies the pits.

Checking the content of bauxite.

The device "Bauxite" allows you to find out the content of alumina in the rock in a matter of minutes.
