REEs present in a bauxite ore end up in its bauxite residue.
Aluminium Fact Sheets Australian Mines Atlas
Aluminium Fact Sheet Bauxite is the ore most commonly mined for aluminium in which aluminium occurs as hydroxide minerals. Aluminium is a silvery-white, Once mined, the next stage in aluminium production is the chemical Bayer Process where alumina (Al2O3) is extracted from bauxite in a refinery. Australia has Aluminium production process Aluminium leader,Aluminium production chain from bauxite mining to recycling aluminium products.
