Description
Technical field
The present invention relates to technical field of desulfurization, in particular to a kind of method using red mud production cement and mixing
Device.
Background technology
Red mud is that the industrial residue discharged after aluminium oxide is refined from bauxite, and average often produces 1 ton of aluminium oxide, attached
Band generates 1.0~2.0 tons of red muds.As the 4th big alumina producing state of the world, the red mud discharged every year is up to millions of for China
Ton.Red mud typically contains more iron oxide, and appearance is similar to redness of the skin or complexion soil, thus gains the name.Some red muds because containing iron oxide compared with
Less and in brown or even canescence.Distinguished in a manner of refining aluminium oxide, red mud be divided into Bayer process red mud, red mud from sintering process,
Combination method red mud.
Since the chemical bases that red mud combines are difficult to remove and content is big, and containing reasons such as fluorine, aluminium and other plurality of impurities,
The innoxious use of red mud is difficult to always.Countries in the world expert has carried out a large amount of science to the comprehensive utilization of red mud
Research, but such progress is little.Therefore, waste red mud residues processing and comprehensive utilization become a global hang-up.
And receive that mainly take is method that disposition is stacked on seabed or land, but with the development of aluminum i ndustry, produce oxygen to the pin of red mud
Changing the red mud amount of aluminium discharge also increasingly increases, and a series of problems caused by stockpiling disposition goes out therewith, causes serious ring
Border problem.
