Does aluminum ingots produced without aluminum ore belong to metal smelting?
Metal smelting is the process of changing metal from a compound to a free state.Metal elements were obtained by reduction reaction with metal oxides such as carbon, carbon monoxide, hydrogen and other reducing agents at high temperature.
The production of aluminium ingots without aluminum ore belongs to metal smelting.Without the use of aluminum ore, aluminum is also extracted from the compound and turned into free aluminum
Smelting principle1. reduction method: metal oxides (together with reducing agents) - free metals2., replacement method: metal salt solution (add active metal) - free metal3. electrolysis: molten metal salts (electrolysis) - - free metals (metal elements)
