A to F below relate to the source and extraction of either Zinc or Aluminium.
A. Bauxite`" "`B. Coke
C. Cryolite`" "`D. Froth floatation
E. Sodium hydroxide solution F. Zine blende
Write down the three letters each from the above list which are relevant to Aluminium

Explanation

To determine which three letters from the list A to F relate to the extraction of Aluminium, we can analyze each option:

1. **A. Bauxite**: Bauxite is the primary ore of aluminium. It is the main source from which aluminium is extracted. Therefore, this is relevant to aluminium.

2. **B. Coke**: Coke is primarily used in the extraction of metals like iron and is not directly related to the extraction of aluminium. Thus, this is not relevant.

3. **C. Cryolite**: Cryolite is another important mineral used in the extraction of aluminium. It is used as a flux in the Hall-Héroult process for aluminium extraction. Therefore, this is relevant to aluminium.
