Abstract
The cobalt melting waste slag haydite short route that the invention discloses a kind of without any other adding ingredient, low cost preparation method, are related to metallurgical slag resource utilization and innoxious process for treating field.The present invention prepares raw material used in haydite and is made of completely cobalt melting waste slag, without adding any other ingredient；Haydite stirs mixed mud the preparation method comprises the following steps: the cobalt melting waste slag that cobalt smelts output is delivered directly in blender, reuses granulating and forming in Doubleroller compaction granulator, calcines after finally drying and haydite finished product is made.Haydite of the invention is light, environmentally friendly, widely used；Cobalt melting waste slag resource utilization is had simplified preparation flow, with good economic efficiency and social benefit by preparation method of the invention.
Description
Technical field
The invention belongs to metallurgical slag resource utilization and innoxious process for treating field more particularly to a kind of no added ingredients
Cobalt melting waste slag haydite and preparation method thereof.
Background technique
Existing heterogenite smelting enterprise is all made of acid leaching process processing cobalt concentrate, and it is useless which can generate a large amount of cobalt smelting
Slag, on the one hand cobalt melting waste slag out occupies a large amount of places mostly based on filling or store up, on the other hand due to cobalt melting waste slag
In contain Active Heavy Metals ingredient, such as manage improperly, easily cause environmental pollution.Cobalt melting waste slag main composition is titanium dioxide
The ingredients such as silicon, ferric hydrous oxide, aluminium oxide and calcium oxide are mainly stored up or are filled to the processing of cobalt melting waste slag at present,
And the problem of environmental pollution that the land occupation problem and its percolate of Large Amount of Co melting waste slag heap buried generate is not solved effectively.
Haydite is a kind of shell in ceramic or the spherical granular material of enamel, has the characteristics that light high-strength and water proof is protected
The effect of gas is mainly used for the substitution in building to concrete medium stone.Traditional haydite be usually with clay and shale sintering and
At a large amount of clays and shale exploited can destroy arable land and natural environment, therefore using solid waste to prepare haydite for raw material is pottery
The developing direction of grain production.
Building porcelain granule is prepared using cobalt melting waste slag as main component, activity weight therein can be solidified by pyroreaction
Metal component and acidic materials eliminate pollution of the cobalt melting waste slag air storage to soil and water resources, and obtain cobalt melting waste slag
Resource utilization.
Summary of the invention
The present invention provides a kind of cobalt melting waste slag haydite and preparation method thereof without any adding ingredient, mainly solves cobalt
The inexpensive harmless treatment and resource utilization problem of melting waste slag.
The technical scheme is that a kind of building porcelain granule of cobalt melting waste slag base, by the raw material of following mass percent
Be prepared: raw material proportioning is 100wt% cobalt melting waste slag, and the cobalt melting waste slag is that acid leaching process is taken to handle heterogenite life
Produce the castaway slag formed in cobalt salt product process, main component are as follows:
| Ingredient | SiO2 | FexOy | CaO | Al2O3 |
| Content | 45-65wt% | 3-10wt% | 4-12wt% | 5-10wt% |
The present invention provides cobalt melting waste slag haydite of such a no added ingredient and preparation method thereof, specifically include with
Lower step: (1) after sending into wet mixer the cobalt melting waste slag after filters pressing to stirring 30-60 minutes, then to be aged 1-2 small
When；(2) it send the cobalt melting waste slag after ageing to the granulating and forming into balling-up granulator, haydite blank is made；(3) by haydite blank
It is dried 1-3 hours at 105 DEG C；(4) the haydite base after drying is entered into sintering furnace, until 1100 DEG C -1200 DEG C of heat preservations 1-2 hours,
Furnace cooling, haydite finished product of coming out of the stove to obtain.
Beneficial effect
Haydite preparation process of the present invention can closely be connected cobalt smelt production, cobalt melting waste slag without carry out stockpiling and
Transhipment, thus the cost of material of prepared haydite is extremely low, realizes cobalt smelting enterprise to the scene of cobalt waste residue exempted to store up, exempt from transhipment
Inexpensive resource utilization.Also, the raw material of 100wt% is that cobalt melting waste slag adds without adding any ingredient in Ceramsite formula
Cobalt melting waste slag after water has stronger viscosity and plasticity, convenient for the granulating and forming of prepared haydite, in cobalt metallurgical slag
Iron, calcium oxide have sintering aids role during ceramisite sintered, can reduce sintering temperature, advantageously reduce ceramisite sintered energy
Consumption, haydite obtained are light, environmentally friendly.Ceramsite preparation process of the present invention is simple, preparation flow is short, and equipment investment is few and manufacturing cost
It is low.Realize the harmless treatment and resource utilization of cobalt melting waste slag, with good economic efficiency and social benefit.
Specific embodiment
Below with reference to embodiment, the present invention is further illustrated.
Embodiment 1
Certain company's cobalt melting waste slag, main component are as follows:
| Ingredient | SiO2 | Fe2O3 | Co | Al2O3 | CaO | Na2O |
| Content | 63.5% | 5.8% | 0.3% | 7.1% | 8.3% | 0.3% |
Cobalt is smelted into process discharge waste residue through filter press filters pressing, send to blender and stirs 30 minutes, be aged 2 hours.Through stirring
Cobalt melting waste slag send into double-roller granulator granulating and forming after mixing ageing, and haydite blank is made.
Haydite blank is dried 3 hours at 105 DEG C.
Haydite base after drying is entered into sintering furnace, 15 DEG C/min of heating rate, until 1150 DEG C keep the temperature 1 hour, furnace cooling,
It comes out of the stove to obtain haydite finished product.
The main performance (see the table below) of obtained ceramic product meets GB_T 17431.1-2010 to the property of artificial lightweight aggregate
It can standard requirements.
| Bulk density | Water absorption rate | Clay content | Cylindrical compress strength |
| 0.8523g/cm3 | 2.04% | 1.3% | 6.63MPa |
The preferred embodiment of the present invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
