Question

Write any one method from which bauxite is extracted

Answer 1

Answer:

cast mining

Explanation:

Bauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the location.

Answer 2

Answer:

In the Bayer process, bauxite ore is heated in a pressure vessel along with a sodium hydroxide solution (caustic soda) at a temperature of 150 to 200 °C. At these temperatures, the aluminium is dissolved as sodium aluminate (primarily [Al(OH)4]−) in an extraction process.
