Australia is one of the world's leading exporters of mineral resources. Iron is obtained from , a rock that contains enough mineral to be economically extracted. Aluminium comes from , and is also found in large quantities in Australia. These minerals are classified as resources because their from the Earth's crust cannot be undone on a human timescale. is one mineral in high demand for electric vehicle batteries, with global demand projected to rise 40 times by 2040. To slow depletion, scientists and governments apply the waste , preferring to materials such as aluminium, which requires only 5% of the energy of primary extraction.
1. Define the term finite resource and give one example from Australia's mining industry.
2. Explain one reason why recycling aluminium is more sustainable than mining new bauxite ore.
