Question

The metal extracted from bauxite is

• A. Copper
• B. Aluminum
• C. Zinc
• D. Gold

Answer 1

The correct option is B

Aluminum

Explanation for correct option:

(B) Aluminium

• Ores can be defined as naturally occurring rocks or sediments from which profitable mining ,extraction of metals or valuable minerals can be done
• Bauxite (${\mathrm{Al}}_2{\mathrm{O}}_{3.}2{\mathrm{H}}_2\mathrm{O}$) is the ore of Aluminium ($\mathrm{Al}$).

Hence , option(B) is correct.

BAUXITE

Explanation for incorrect options:

(A) Copper

• Copper ($\mathrm{Cu}$) can be extracted from Malachite(${\mathrm{CuCO}}_3.\mathrm{Cu}{\left(\mathrm{OH}\right)}_2$) , Azurite($2{\mathrm{CuCO}}_3.\mathrm{Cu}{\left(\mathrm{OH}\right)}_2$) ,Cuprite(${\mathrm{Cu}}_2\mathrm{O}$) , Copper glance(${\mathrm{Cu}}_2\mathrm{S}$) , Copper pyrites(${\mathrm{CuFeS}}_2$)
• Copper can not be extracted from Bauxite.

(C) Zinc

• Zinc($\mathrm{Zn}$) can be extracted from Sphalerite($\mathrm{ZnS}$), Zincite($\mathrm{ZnO}$) ,Franklinite($\mathrm{ZnO}{(\mathrm{Fe},\mathrm{Mn})}_2{\mathrm{O}}_3$) ,Calamine(${\mathrm{Zn}}_2{\left(\mathrm{OH}\right)}_2{\mathrm{SiO}}_3$) and Smithstone(${\mathrm{ZnCO}}_3$)
• Zinc can not be extracted from Bauxite.

(D) Gold

• Native gold is the most common ore of Gold($\mathrm{Au}$)
• Other ores may include Calaverite(${\mathrm{AuTe}}_2$) , Sylvanite($(\mathrm{Au},\mathrm{Ag}){\mathrm{Te}}_2$) ,Petzite(${\mathrm{Ag}}_3{\mathrm{AuTe}}_2$) and Krennerite(${\mathrm{Au}}_3{\mathrm{AgTe}}_8$).
• Gold can not be extracted from Bauxite.

Hence , option(B) is correct. The metal extracted from bauxite is Aluminium.
