The difference between electrolytic aluminium, alumina and aluminium ingot
Two, the production process is relatively speaking, the process of alumina production is more complex, the production of a ton of aluminum ingots require about two tons of alumina, the product must be expensive to produce aluminum ingots.
You said, "the aluminum factory also needs bauxite," then the aluminum smelter is not necessarily a single electrolytic aluminum plant, there may be other production processes.
Two the production process is different, one is from bauxite by a series of chemical reactions, to aluminum hydroxide, then baking system of alumina, electrolytic aluminum is alumina powder electric melting, electrolytic aluminum ingot.
