Description
Technical field
The present invention relates to basic industry waste material and the construction material of mine iron tailings composition, belong to industrial solid wastes money
Source recycling field, specifically related to a kind of mine tailing, alkaline residue, slag gel material agitating device and preparation technology.
Background technology
The mine tailing bulk deposition that the barren rock and ore dressing that the Yanshan Mountain, the exploitation of Taihang Mountain metal mine are peeled off for over 100 years more than a hundred years are produced, such as：
Baoding northwestward district, Chengde whole area and Tangshan City the north district, which amount to, more than 40 hundred million tons of storages, wherein only iron tailings is just accounted for
More than 90%, a large amount of soils are taken, environment is polluted.In recent years, though the comprehensive utilization to iron tailings is inquired into, not enough into
It is ripe, because its activity is low, it is difficult to be excited, utilization rate is extremely low, therefore this project uses alkaline residue as solid exciting agent, improves it
Activity, and then increase its utilization rate.Big choline factory and Tangshan alkali factory positioned at Modern Agriculture in Hebei Coastal Region produce 1,700,000 tons of alkali every year
Slag, these alkaline residues are deposited directly at estuary coast band, not only polluted underground water, take a large amount of land resources, and substantial amounts of
White alkaline residue powder destroys natural environment.It is right although by the exploration of more than 100 years, have accumulated some control measures and experience
The alkaline residue of ammonia-soda process soda manufacture discharge does not find the method for radical cure also.
Make full use of mine tailing to replace natural mineral resource, the exploitation of natural non-metallic ore resources can be greatly decreased, protect
Blue mountains and green waters, constructs Beijing Tianjin and Hebei Region solid waste and utilizes circulating system, for economizing on resources, and improves environment, improves economic effect
Benefit, ecological protection, and to realizing that Jing-jin-ji region most optimum distribution of resources and sustainable development all have great importance, comply fully with
The national strategy requirement of Jing-jin-ji region cooperative development.
In the research and development of existing gel rubber material for building, although constantly seeking and developing to use based on waste material
Class cement material, but in these combination species cement materials mostly all still based on cement, not only high cost, and many institute's weeks
Know, the production process of cement can produce substantial amounts of CO2Waste gas is discharged, severe contamination environment.At present, number of patent application is：
In the patent document of 201610378285.1 " a kind of mine tailing cementing agent ", applicant describes a kind of tailings cementing agent, butt
It is slag 5%~12%, flyash 1%~5%, slag 4%~6%, lime mud 3%~6%, cement according to percentage by weight
Clinker 5%~20%, industry by-product gypsum 2%~10%, CHARACTERISTICS OF TAILINGS SAND 75%~90%；Raw material butt and water percentage by weight
For：Raw material butt 65%~75%, water 25%~35%.Each component weight percent according to raw material butt, which coordinates, to be mixed,
Mass concentration needed for slurry is added water move to, Mine filling cementing material slurry is made in agitated machine stirring.Still make in this binder materials
With a large amount of cement, not only high cost, the and it is well known that production process of cement can produce substantial amounts of CO2Waste gas is discharged, sternly
Heavily contaminated environment.Number of patent application is：A kind of 201410542602.X " alkaline residue base class cement gel material ", applicant introduces
Binder materials be by the alkaline residue of 40%~60% (quality), the flyash of 40%~60% (quality) and account for alkaline residue+flyash
The composition of the activating agent composition of total amount 10%~20% (quality)；First by the desired amount of alkaline residue of definite quality percentage with
Flyash is well mixed, then adds the activating agent for accounting for the mixture gross mass 10%~20% (quality) thereto, is then stirred
Uniformly, that is, a kind of alkaline residue base class cement gel material is obtained.Though this species cement cementitious material has used a large amount of alkaline residues, simultaneously
Substantial amounts of flyash and waterglass are also consumes, it is uneconomical.
