(b) Durg
(c) Kondagaon
(d) Dhamtari

Correct Answer: (c) Kondagaon

Solution:According to IMYB, 2021, Bauxite mineral is available in Kabirdham, Kondagaon and Surguja districts of Chhattisgarh.

Titania is present as leucoxene or rutile. Bauxite is formed from laterite soil, a reddish clay material. It's most commonly found in tropical or subtropical regions. Bauxite is refined into alumina through the Bayer chemical process. Alumina is then refined into pure aluminum metal through the Hall-Héroult electrolytic process. Bauxite is found in abundance at many locations around the world, including Australia, China, Brazil, India, Guinea, Jamaica, Russia, and Kazakhstan. Bauxite residue can cause environmental and air pollution.
