Aluminium, Alumina and Bauxite
Alumina is the key raw material used to produce primary aluminium. Mined bauxite ore is refined into alumina through what is known as the Bayer process. The process, discovered in 1887, extracts alumina from bauxite through crushing, dissolving it in caustic soda, filtration and an electrolytic process.

Supply Chain in Mining: The Race for Critical Raw Materials
The CRMA names 34 critical raw materials and 17 strategic raw materials. The agreement sets benchmarks for domestic extraction (10%), processing (40%) and recycling (25%). These benchmarks will put increased pressure on the mining and processing industry to ramp up their domestic production capabilities and revisit their supply chains.

Capturing the green-premium value from sustainable materials
Materials value chains—including metals and mining, building materials, plastics, and packaging—account for around 20 percent of global greenhouse-gas (GHG) emissions.Some of these value chains are also often wasteful: 98 percent of construction materials end up in low-value end-of-life applications, and only 17 percent of annual plastics are recycled.
