Chapter 21, Problem 21.8QP

Interpretation Introduction

Interpretation:

The preparation of aluminum from its ore has to be drawn and each step has to be labeled.

Concept Introduction:

Aluminum from its ore can be done by the following methods.

Bayer process:

• This process is used to refine bauxite to get alumina (aluminum oxide).
• The raw material which is used in this process is called bauxite.
• The temperature which is used in this process is $\text{150 to 200 °C}\text{.}$

Hall-Heroult process:

• This is the process which can use for smelting aluminum.
• In this process electrolyzing molten salt bath is used and built typically a purpose-built cell.
