Where does aluminium come from?

Answer 1

Aluminum is all around us, in almost every rock, plant, and animal.
It is the third most plentiful element in the earth's surface, after oxygen and silicon, its mix makes up about 15 percent of the weight of the earth's crust. But nowhere in nature is aluminum found in a pure form — it's always mixed with other elements.
Aluminium comes from bauxite. This is a red soil type, which can be found in many countries all over the world. Bauxite lies in the surface of the earth. This is why it is possible to dig bauxite out of mines. The world’s largest bauxite mines are in Australia, China, Brazil, Guinea, Jamaica and Iceland.
