Question

Why is bauxite the most common ore that aluminum is extracted from select the two correct answers.
It can be refined in a single step
It is located near the surface and can be easily strip mined
It contains pure aluminum metal
It is the most ubandsnt ore of aluminum
It is also used in jewelry as a gem

Answer 1

The two correct answers regarding why bauxite is the most common ore from which aluminum is extracted are:

1. **It can be refined in a single step** - Bauxite can be processed with the Bayer process, which allows for the extraction of aluminum oxide (alumina) in a relatively straightforward manner.

2. **It is located near the surface and can be easily strip mined** - Bauxite deposits are typically found close to the earth's surface, making them accessible for mining operations, particularly strip mining.

The other options are incorrect because:
- Bauxite does not contain pure aluminum metal; it is an aluminum ore that needs to be processed to extract aluminum.
- It is not necessarily the "most abundant" ore of aluminum but is the primary source used for aluminum extraction due to its favorable properties.
- Bauxite is not used in jewelry as a gem; rather, aluminum is the metal extracted from it.
