Description
Technical field
The present invention relates to the techniques of a kind of potassium feldspar and ardealite recycling aluminium by-product Fertilizer special for eggplant, belong to chemical metallurgy neck
Domain.
Background technique
Eggplant alias:Eggplant, short melon hang vegetable seeds, fall Soviet Union, green eggplant, purple eggplant, white eggplant, draft or semishrub plant, and up to 1 meter.
Eggplant belongs to a member in Solanaceae family, is homely vegetable very common on one of purple vegetables few in number and dining table
Dish.Edible portion is 93%.Energy content 88kJ in every 100g, moisture 93.4g, protein 1.1g, fat 0.2g, dietary fiber
1.3g, carbohydrate 3.6mg, 50 μ g of carrotene, 8 μ g of retinol equivalent, thiamine 0.02mg, riboflavin 0.04mg, Ni Ke
Sour 0.6mg；Wei Shengna C5mg ties up raw family E1.13mg；Potassium 142mg, 5.4mg, calcium 24mg, magnesium 13mg, iron 0.5mg, manganese
0.13mg, zinc 0.23mg, copper 0.1mg, phosphorus 2mg, selenium 0.485g.Medicinal ingredient has solanine etc..
The solid slag that ardealite generates when referring in phosphoric acid production with sulfuric acid treating phosphorite, main component are sulfuric acid
Calcium (CaSO4), content generally can reach 70~90% or so.In addition, ardealite also contains plurality of impurities：Undecomposed phosphorus
Mine, phosphoric acid, calcirm-fluoride, iron, aluminium compound, acid non-soluble substance, organic matter of non-washes clean etc..
Potash feldspar ore is that potassium content is higher, distribution is most wide, the maximum water-insoluble potassium resource of reserves, belongs to monoclinic system, is led to
It is often in flesh-coloured yellowish-white equal colors, theoretical composition SiO264.7%, Al2O318.4%, K2O 16.9%, average oxidation potassium contain
Measure about K2O 11.63%, reserves about 79.14 hundred million t, is mainly used for glass, ceramics, it may also be used for produce potash fertilizer, quality compared with
Good potassium feldspar is for manufacturing TV imaging glass bulb etc..
It is existing currently, in the fertilizer that eggplant plantation uses, mainly using potash fertilizer and calcareous fertilisers as main base manure, mixing urea,
It is prepared after the ingredients such as monoammonium phosphate, boric acid, magnesium sulfate, ferric sulfate, manganese sulfate, zinc sulfate, sodium selenite and humic acid, and
Conventional potash fertilizer and calcareous fertilisers is pure potassium fertilizer and calcium fertilizer, such as potassium chloride, potassium sulfate, potassium dihydrogen phosphate and calcium nitrate, sulphur
The potassium calcium base manure preparation cost of sour calcium and calcium dihydrogen phosphate etc., this kind of pure element is higher, for this purpose, due to ardealite and potassium feldspar
It is middle respectively contain a large amount of calcium constituent and potassium element, meanwhile, ardealite as phosphoric acid preparation when waste residue environment can be caused sternly
The destruction of weight, and potassium feldspar is as a kind of main sylvite ore, content in nature is larger, and use cost is lower,
So that ardealite and potassium feldspar become the new selection for preparing potassium calcium base manure.
It is directly by ardealite and feldspar in powder but now at present in the technique that ardealite and potassium feldspar prepare fertilizer
It is prepared after being mixed after broken with other compositions, due to containing a large amount of element sulphur in ardealite, and containing a large amount of in potassium feldspar
Aluminium ion, aluminium hydroxide easy to form after aluminium ion enters in soil makes to release hydrogen ion in soil, destroys the acid of soil
Alkalinity influences the growth of crop, meanwhile, aluminium element and element sulphur are not recycled further, and phosphorus is greatly reduced
The added value of gypsum and potassium feldspar.
For this purpose, this researcher is analyzed by component content to potassium feldspar and ardealite and chemical characteristic, study
A kind of comprehensive processing technique of ardealite and potassium feldspar, can greatly improve the added value of ardealite and potassium feldspar, there is it
Valence ingredient is fully used, and the growth of eggplant is combined to need, and has made Fertilizer special for eggplant, wherein passing through this process
Aluminium ion is recycled afterwards, greatly reduces destruction of the special fertilizer to eggplant planting site soil ph, it is right
The utilization of residue phosphogypsum and potassium feldspar provides a kind of new approaches.

From obtaining containing a large amount of potassium and calcium in the residue after flotation, can directly doing the use of potassium calcium base manure after filter residue floatingly selects sulfide,
It is required according to the need fertilizer of eggplant, is rationally equipped with urea, monoammonium phosphate, boric acid, magnesium sulfate, ferric sulfate, manganese sulfate, zinc sulfate, Asia
Sodium selenate and humic acid simultaneously mix, and are granulated, can be prepared by Fertilizer special for eggplant, which is very suitable for the plantation of eggplant, and potassium is long
Aluminium in stone is recycled, and the destruction of metallic aluminium ion pair soil is avoided, and improves the fertilizer efficiency of Fertilizer special for eggplant.
3, the present invention first roasts potassium feldspar, ardealite, additive and modifying agent, and product is without organic after roasting
Object is easily isolated, then can be obtained the clearly demarcated product of ingredient after water mill dissolves out and is separated by solid-liquid separation, product be mainly silicate,
Metal sulfide and sodium aluminate almost contain only the sodium aluminate for being highly soluble in water in isolated liquid, are passed through CO2After be
The aluminium product of recyclable high-purity, while this method has very high aluminium recovery.
To detect effect of the invention, inventor has done following experiment：
The rate of recovery and purity of aluminium oxide obtained in embodiment 1-5 are detected respectively, the results are shown in Table 1：
Table 1
| Project | Embodiment 1 | Embodiment 2 | Embodiment 3 | Embodiment 4 | Embodiment 5 |
| The rate of recovery/% | 96.2 | 95.8 | 95.7 | 96.3 | 96.1 |
| Purity/% | 99.3 | 99.2 | 99.1 | 99.5 | 99.3 |
It is applied fertilizer respectively using Fertilizer special for eggplant obtained by embodiment 1-5 to the long eggplant eggplant in Suzhou, meanwhile, it utilizes
The direct mixing urea of potassium feldspar, monoammonium phosphate, boric acid, magnesium sulfate, ferric sulfate, manganese sulfate, zinc sulfate, sodium selenite and humic acid
After be fabricated to control group 1 and apply fertilizer, 2 applied fertilizer as a control group using Common compound fertilizer, Common compound fertilizer it is main at
It is divided into urea, phosphorus ammonium and potassium chloride, wherein nitrogen, phosphorus and potassium available nutrient content >=25%；Fertilization mode is identical in acid-base property
Same a piece of eggplant subregion carried out respectively with each group fertilizer conventional fertilizer application to eggplant maturation, during which measure corresponding eggplant in five times
The pH value of sub- ground soil；Meanwhile after harvest home, average fruit weight and per mu yield are calculated.The results are shown in Table 2 for it：
Table 2
| Project | Single fruit weight (g/) | Per mu yield (kg) | PH range |
| Embodiment 1 | 109 | 3127 | 6.6-7.6 |
| Embodiment 2 | 110 | 3118 | 6.5-7.5 |
| Embodiment 3 | 112 | 3154 | 6.6-7.4 |
| Embodiment 4 | 113 | 3122 | 6.5-7.3 |
| Embodiment 5 | 111 | 3136 | 6.4-7.4 |
| Control group 1 | 93 | 2834 | 6.1-6.9 |
| Control group 2 | 101 | 2897 | 6.5-7.4 |
From table 2 it can be seen that the quality and yield of eggplant are significantly improved, this is after using fertilizer of the invention
Because the acid-base property of soil is not destroyed, the soil of the pH value in the section is more favorable for eggplant to the fertilizer such as potassium, calcium member
Therefore the absorption of element increases yield.And it is directly being applied using manufactured fertilizer after potassium feldspar and ardealite mixing other elements
After fertilizer, the acid-base balance of soil is destroyed, keeps soil weakly acidic, is unfavorable for the absorption of fertilizer efficiency, reduces the yield of eggplant.
