Australia is the world’s leading producer of a. diamonds b. gold c. bauxite d. iron ore plzzz !

C. Bauxite

Explanation:

The correct answer is C. bauxite.

Explanation:

Australia is considered the main producer of bauxite around the world. Australia has five mines of bauxite which serve as feedstock to the alumina's refineries.

Gove and Weipa are two of the five bauxite mines that we can find in Australia. These two mines have about 50 percent of alumina and are considered the highest grade deposits in the world. However, the majority of deposits in Australia have great amounts of silica, which is considered a disadvantage because this requires that the deposits utilize caustic soda in large quantities and in this way the costs of alumina refining would rise.
