Description
Technical field
The present invention relates to a kind of phosphate rock floating combination medicaments and its application method for high-silicon high magnesium, belong to mineral floating
Pharmaceutical arts.
Background technology
Phosphate rock resource is a kind of non-renewable nonmetal mineral resource, is widely used mainly in the necks such as agricultural, chemical industry, medical treatment
Domain is especially agriculturally contributed, and it is 3,700,000,000 t that phosphate rock resource, which plays important role China rock phosphate in powder reserves, occupies the world
2nd, the 5.52% of world's total amount is accounted for, China's phosphorus ore is mainly distributed on Hubei, Yunnan, Guizhou, Sichuan and five, Hunan province, phosphorus
Mine is second-rate, and most of phosphorus ore grades are less than 25%.It is counted according to Chemistry In China mining industry association, the rock phosphate in powder of China 80.5% is used
In production phosphate fertilizer, Chinese phosphorus deposit type is various, mainly there is Sedimentary phosphorite type, magmatic rock apatite-type and rotten phosphorite type
Three kinds, wherein sedimentary rock type phosphorus ore accounts for the 75.5% of whole phosphate rock resources, and rotten and magmatic phosphate deposit accounts for 24.0%, China's phosphorus ore
The features such as few with rich ore, lean ore is more, and easy ore dressing is few, and difficult ore dressing is more.Identified phosphorus ore reserves 97.5% are middle-low grade phosphorus
Mine, wherein nearly 70% is the collophane of middle-low grade, for the rock phosphate in powder of difficult choosing generally acknowledged both at home and abroad.
If carbonate and silicate gangue of the rock phosphate in powder middle arteries stone ore owner based on magnesium and silicon, and current phosphate rock floating
The collecting agent used is mainly the collecting agent based on fatty acid, to based on magnesium and calcium carbonate gangue equally have compared with
Good collecting effect, so generally require to add the inhibitor such as a large amount of waterglass in phosphate rock floating for inhibiting gangue, but
Inhibition is still bad, causes the content of magnesium in phosphorus concentrate higher, influences concentrate quality.Therefore it is strong how to develop selectivity
Collectors for Phosphorous Ore be always professional person's tackling key problem project, for adequately and reasonably utilizing phosphate rock resource, to pushing national warp
The development of Ji has great importance.
Invention content
The present invention is directed to the problem of existing phosphorite flotation collector poor selectivity, provides a kind of phosphorus for high-silicon high magnesium
Mine flotation combination medicament, which has preferable selectivity to the higher rock phosphate in powder of siliceous and magnesium, particularly with ore
Forming complex, the thinner collophane of down cloth granularity has preferable flotation effect, need not add or add in flotation
Add a small amount of inhibitor that can reach preferable separating effect.
To achieve the goals above, the invention is realized by the following technical scheme：
A kind of phosphate rock floating combination medicament for high-silicon high magnesium, each raw material and its mass percent are in the combination medicament：α-
20 ~ 60wt% of amino acid, 20 ~ 60wt% of palmityl glycine, 5 ~ 40wt% of diesel oil.
Method by the combination medicament for the phosphate rock floating of high-silicon high magnesium, specially：To first contain phosphorus ore ore grinding to-
0.074mm accounts for 40% ~ 80%, then adds the pH regulator sodium carbonate g/t of 100g/t ~ 1000, inhibitor waterglass 0g/t ~ 1000
G/t finally adds combination medicament 20g/t ~ 300 g/t.
The present invention has the advantages that：
（1）Three kinds of medicaments used in the combination medicament are a-amino acid, palmityl glycine and diesel oil, are all conventional dose, are held
It easily obtains, three kinds of medicaments are applied in combination by a certain percentage can form synergistic effect, have stronger selection in phosphate rock floating
Property；Meanwhile collecting ability can be remarkably reinforced for independent addition, achieve the effect that improve floatation indicators, reduces medicine
The consumption of agent reduces production cost.
（2）When using the combination medicament flotation phosphorus ore, there is stronger selectivity, it is few without addition or addition when flotation
The inhibitor of amount can obtain ideal separating effect.
（3）To ore properties, complicated, down cloth fine size collophane has preferable flotation effect, production to the combination medicament
It is at low cost.
