Answer:
Aluminum
Step-by-step explanation:
In the earth's crust, we found different types of rock. The rock contains many minerals and inorganic materials. Some rocks are a good source of many metals. This type of rock is called ore. Bauxite is also one ore that contains a heavy amount of aluminum. For this reason, it is called aluminum ore.
Bauxite is a sedimentary rock. It contains different components such as silica, sand, iron oxides, and aluminum oxides which later give rise to aluminum. The color of bauxite is of different types, light pink, orange or reddish.
The aluminum from the bauxite ore is extracted by two methods - Bayer's method. In this method, the aluminum oxide/alumina is formed.
Then the second method is used to extract aluminum from alumina i.e. Haul - Heroult process.
Aluminum is used in many industries, making steel. etc.
