General Principles and processes of Isolation of Elements
medium
In the extraction of aluminium
process $X$ : applied for red bauxite to remove iron oxide (chief impurity)
process $Y$ : (Serpeck's process) : applied for white bauxite to remove $Z$ (chief impurity) then,
process $X$ and impurity $Z$ are
A
$X =$ Hall and Heroult's process and $Y = SiO _2$
B
$X =$ Baeyer's process and $Y = SiO_ 2$
C
$X =$ Serpeck's process and $Y =$ iron oxide
D
$X =$ Baeyer's process and $Y =$ iron oxide
Solution
Bayer's process is used for benficiation of red bauxite. Serpeck's process is used for benficiation of white bauxite.
Reaction to remove impurity;
$SiO _2+2 C \rightarrow Si +2 CO$
