Question

In Red Bauxite, the major impurity is $Ti{O}_2$ – True or False?

• A. True
• B. False

Answer 1

The correct option is B

False

Red bauxite $\left(A{l}_2{O}_3.2H_{2}O\right)$ contains $F{e}_2{O}_3$ $+Ti{O}_2$ $+Si{O}_2$ of which $F{e}_2{O}_3$ is the major impurity. On the other hand, white bauxite has significantly more silica (white) than $F{e}_2{O}_3$.
