Abstract
The invention discloses one kind to be used for phosphate reverse flotation combination medicament and its application method, each raw material and its mass percent in the combination medicament are as follows: 20 ~ 60wt% of lauryl amine, 20 ~ 60wt% of octadecanoid acid, 5 ~ 40wt% of sodium carbonate.Combination medicament of the present invention is mixed according to a certain percentage, the collecting ability and selectivity that phosphorus ore is improved by the synergistic effect between medicament have reagent consumption few for single phosphorite flotation collector, cheap advantage, and room temperature is solvable, nontoxic, high-efficiency environment friendly；There is preferable selectivity containing the higher rock phosphate in powder of magnesium especially for siliceous, the recycling for improving phosphate rock resource is of great significance.
Description
Technical field
The present invention relates to a kind of phosphate reverse flotation combination medicament and its application methods, belong to mineral floating pharmaceutical arts.
Background technique
Phosphate rock resource is a kind of non-renewable nonmetal mineral resource, is widely used mainly in the neck 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 lower 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 multiplicity, mainly there are 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 magnesium and it is calcareous based on carbonate gangue equally have
Preferable collecting effect, so generally require to add the inhibitor such as a large amount of waterglass in phosphate rock floating for inhibiting gangue,
But inhibitory effect is still bad, causes the content of magnesium in phosphorus concentrate higher, influences concentrate quality.Therefore how selectivity is developed
Strong Collectors for Phosphorous Ore is always the project of professional person's tackling key problem, national to pushing for adequately and reasonably utilizing phosphate rock resource
Expanding economy has great importance.
Summary of the invention
The present invention proposes a kind of phosphate reverse flotation combination medicine aiming at the problem that existing phosphorite flotation collector poor selectivity
Agent, the medicament have stronger collecting ability to containing gangue minerals such as magnesium, silicon, form complex, down cloth particularly with ore
The thinner collophane of granularity have preferable flotation effect, only need to add in reverse flotation a small amount of medicament can reach compared with
Good separating effect.
To achieve the goals above, the invention is realized by the following technical scheme:
One kind being used for phosphate reverse flotation combination medicament, each raw material and its mass percent in the combination medicament are as follows: and lauryl amine 20 ~
60wt%, 20 ~ 60wt% of octadecanoid acid, 5 ~ 40wt% of sodium carbonate.
The method that combination medicament of the present invention is used for phosphate reverse flotation, specifically: first by phosphorus ore ore grinding to -0.074mm
40% ~ 90% is accounted for, sulfuric acid 1kg/t ~ 15kg/t is then added, finally adds combined capturing and collecting agent 20g/t ~ 500 g/t.
The principle of the present invention: lauryl amine has amido functional group, and polar group can be generated with the calcium ion on phosphorus ore surface
Complex compound, hydrophobic group is outside, to make phosphorus ore surface hydrophobicity；Octadecanoid acid has amino and carboxyl functional group simultaneously, for floating
Carboxyl and amino can be reacted with the calcium ion on phosphorus ore surface when selecting phosphorus ore generates chelating object, and stable is adsorbed in apatite table
Face makes hydrophobic group outwardly, promotes phosphorus ore surface hydrophobicity；The addition of sodium carbonate makes having for lauryl amine and two kinds of collecting agents of octadecanoid acid
Effect component reaches an optimal existence；Three kinds of medicaments are applied in combination by a certain percentage can form synergistic effect, make it
Adsorption capacity on gangue mineral surface enhances, and reaches raising floatation indicators, reduces the consumption of medicament, reduces the effect of production cost
Fruit.
The present invention has the advantages that:
(1) three kinds of medicaments used in combination medicament of the present invention are lauryl amine, octadecanoid acid and sodium carbonate, are all conventional medicine
Agent is easy to get, cheap.
(2) when combination medicament of the present invention is used for phosphate reverse flotation, there is stronger collecting ability to gangue mineral, only
A small amount of medicament, which need to be added, can obtain ideal collecting effect.
(3) to ore properties, complicated, down cloth fine size collophane has preferable separating effect to combination medicament of the present invention,
Reagent consumption is few for single drug, and production cost is low.
