Question

Bauxite is mined in large quantities at 
1. Panna Mines
2. Katni Mines
3. Durg Mines
4. Baster Mines

Answer 1

Correct Answer - Option 2 : Katni Mines

The Correct Answer is "Katni Mines".

• Katni Mines are the largest producer of Bauxite in Tehsil Murwara, District Katni (M.P.)
• Bauxite is basically an aluminous rock that contains hydrated aluminum oxide as a main constituent and iron oxide, silica & titania as minor constituents present in varying proportions.

 

• Hydrated aluminum oxides present in the bauxite ore are diaspore and boehmite, Al2O3 .H2O (Al2O3 -85%; Al-45%); gibbsite or hydrargillite, Al2O3 .3H2O (Al2O3 - 65.4%; Al-34.6%), and bauxite (containing colloidal alumina hydrogel), Al2O3 .2H2O (Al2O3 -73.9%; Al39.1%).
• The iron oxide in bauxite ore is present as haematite or goethite; silica as clay; and free quartz & titania as leucoxene or rutile.
• Bauxite is the principal ore of aluminum which is one of the most important non-ferrous metals used in modern industry.
• It is also an essential ore for Refractory and Chemical industries.
• The country has 3,896 million tonnes of resources of bauxite which is sufficient to meet both domestic and export demands.
