Description
Technical field
The present invention relates to technical field of mineral processing, it particularly relates to a kind of cleaning containing high alumina high silicon high iron class ore deposit
High-efficiency comprehensive utilization method.
Background technology
Mineral Resources in China has that lean ore is many, rich ore, easy ore dressing are few, and middle-size and small-size ore deposit is many, large ore is few, complicated component
Altogether, feature that associated minerals ore deposit many, single is few, due to random mining for many years, adopt richness abandon lean, dressing and smelting process falls behind, environmental consciousness relatively
The reasons such as difference cause that most of Products of mine is single, tailing heap storage greatly, mine tailing does not utilizes component more and ecological ring
Border is destroyed serious, and therefore, environmental protection, energy-conservation, comprehensive high-efficiency utilize mineral resources to be the necessarily choosing of current era mining development
Select.Although, Mineral Resources in China comprehensively utilizes and achieves greater advance nearly ten years, but Mineral Resources in China comprehensive utilization generally
With still being restricted by factors such as regional economy, scope of the enterprise, technical merits, level is uneven, gap is bigger.According to statistics,
Mineral Resources in China overall recovery and intergrowth mineral produce comprehensive resource utilization rate and are respectively 30% and about 35%, than abroad first intake
Flat low by about 20%, also have bigger gap compared with developed countries.Containing high alumina high silicon high iron class ore deposit often due to disseminated grain size is thin,
Mineral composition is complicated, belongs to difficult mining seam.At present, such ore deposit can only be reclaimed small part valuable element therein, and wherein
Most of valuable element be still lost in tailings, part ore deposit even can't effective exploitation utilize.Such as high ferro height siallite
Ore deposit, it is necessary first to desiliconization, could extract aluminium oxide further, possibly together with many valuable element such as scandium, germanium, gallium, titanium, ferrum in red mud
Deng, and for example silicic acid nickel minerals, phosphorus potassium ore deposit etc. the most still can not get effective exploitation.
For the problem in correlation technique, effective solution is the most not yet proposed.
Summary of the invention
For the above-mentioned technical problem in correlation technique, the present invention proposes a kind of comprehensive utilization containing high alumina high silicon high iron class ore deposit
By method, it is possible to realize mineral resources and the high-efficiency comprehensive utilization of the energy, cleaning produce, anury discharge.

Crystallization obtains ammonium aluminum sulfate crystal (can recrystallization purify further), and crystallization temperature is generally 10～40 DEG C, can not change
Under conditions of the character of acid leaching liquor, aluminum is made first to separate with the valuable element in leachate and ferrum；
S3 uses solvent extraction substep from acid leaching liquor to reclaim valuable metal element；Can be according to valuable metals different in solution
Element uses different conventional extraction isolation technics, as used P204 extract and separate scandium, uses N1923 extract and separate titanium etc.；
S4 uses evaporation and concentration spent acid, may return to leaching system use again after being concentrated to finite concentration, and thickening temperature typically may be used
Control at about 180～220 DEG C, concentrate acidity and can require generally 40%～70%(volume fraction according to leaching ore deposit), waste acid concentration
While crystallize out iron sulfate and ferrous sulfate by-product；
S5, by building supporting pyrite-based sulfuric acid production system, first provides sulphuric acid, fall for the leaching containing high alumina high silicon high iron Ore
Low cost of material, it is often more important that make full use of antacid waste hot steam as leaching, crystallization, recrystallization, waste acid concentration and each
Valuable metal elements by extraction removal process needs the thermal source heated, the energy consumption of whole utilization system can be greatly lowered；
Moreover, iron sulfate and ferrous sulfate that waste acid concentration produces (generally mass ratio 25～35%) can join ore deposit to sulfur in appropriate proportions
Iron mine is prepared sulphuric acid, pyrite cinder can as iron-smelting raw material, comprehensively utilize the iron sulfate that goes out of spent acid evaporating, concentrating and crystallizing and
Ferrous sulfate.
Further, in step S1, high-silicon high aluminum high ferro ore reduction ore grinding will be contained to certain fineness, fineness generally-
It is 65%～95% that the Ore of 200 mesh accounts for mass percent, normal pressure sulfuric acid leaching in a kettle., carries by increasing sulfuric acid concentration
High extraction temperature, general sulfuric acid concentration (volume fraction) controls 40%～70%, and extraction temperature can get 100～180 DEG C, permissible
Ferrum in Ore, titanium, aluminum and other valuable element being proceeded to liquid phase, it is achieved efficiently leach, controlling solid-liquid separation temperature is 70
～90 DEG C, the amorphous silica that available purity is higher, general purity is up to about 95%.
Beneficial effects of the present invention:
(1) in atmospheric conditions, improve extraction temperature by increasing sulfuric acid concentration, directly efficiently leach the aluminum in Ore and
Other valuable element (without pretreatment such as roast ores), obtain purity higher can be as high-quality siliceous fertilizer, white carbon, water glass
The quality raw materials amorphous silica of glass, calcium silicate material etc., it is achieved anury discharges；
(2) use vacuum crystallization or crystallisation by cooling to prepare Burnt ammonium alum and first isolate aluminum, then use solvent extraction from acidleach
Go out substep in liquid and reclaim valuable metal element, and evaporation and concentration spent acid is isolated iron sulfate and ferrous sulfate and returns antacid,
Realize the high-efficiency comprehensive utilization of resource；
(3) evaporation and concentration is used to recycle spent acid, it is achieved cleaning produces；
(4) provide sulphuric acid by the supporting pyrite-based sulfuric acid production system of construction, and make full use of waste hot steam as each operation
Thermal source, it is achieved the efficient utilization of the energy.
