Abstract
The invention discloses a collecting agent for low-grade gold ores. The collecting agent comprises, by weight, 30-34 parts of diltiazem nitrile ester, 10-12 parts of alkyl xanthate acrylonitrile ester, 10-12 parts of ammonium dibutyl dithiophosphate, 1-2 parts of sodium hydroxide, 17-19 parts of styrene phosphoric acid, 3-4 parts of 4-butanediol vinyl ether, 1-2 parts of potassium dichromate, 2-3 parts of sodium metasilicate, 2-3 parts of diphenyl ethyl phenol-compounded polyoxyethylene ether, 1-2 parts of oleic acid polyoxyethylene ester, 5-7 parts of 2-peracetic acid-group butyric acid and 10-20 parts of activator. The collecting agent has the advantages that the collecting agent can realize capturing and foaming effects, foams are stable, and the collecting agent is high in collection capacity, so that the gold ores are high in recovery rate, selectivity and grade; owing to the activator, surface hydrophobic properties of the gold ores can be changed, internal structures of the gold ores can be activated, accordingly, the gold ore collection performance of the collecting agent can be improved, characteristics of the collecting agents can be played for the low-grade gold ores, the gold ores are high in recovery rate, and gold is high in grade.
Description
Technical field
The present invention relates to mineral floating technical field, particularly a kind of low-grade gold collecting agent and preparation method thereof.
Background technology
The enrichment method of gold mine is except leaching, and majority selects factory or selective flotation method reclaims gold mineral.At present gold mineral there is is the collecting agent of better collecting effect to have puratized agricultural spray black powder, butyl ammonium aerofloat, catches the floating agents such as Jin Ling, Y-89, M16, QF, conventional flotation medicament is stronger to the collecting ability of gold mine, but selectively poor, the large problem that exists that gold recovery is low, index fluctuates, flotation effect is undesirable, the problem that resource utilization is low.
The research application of novel, the efficient combined flotation medicament of carrying out around improving golden mineral processing index in recent years, has obtained greater advance.Research and application aspect at new and effective medicament are especially outstanding to change surname medicament.Medicament modification comprises: in existing medicament, introduce energy improvement and strengthen the force of reagents and interactional other active group of mineral surfaces; Develop individual water-soluble chelating or complexing medicament; Selection has two kinds and various medicaments combination and mixed reagent of different activities and function.Although the research of gold ore flotation medicament has obtained significant progress, but in floatation process, still understand because of partially carbonized thing adsorpting formulation, or other reason, the loss to a certain degree of gold caused, the problem that gold mine taste differs, causes damage to enterprise and society.
Summary of the invention
The object of this invention is to provide a kind of low-grade gold collecting agent and preparation method thereof, this collecting agent has collecting and foaming double attribute, and selectively good, collecting ability is strong, is applicable to the feature of the choosing gold of low-grade gold.
Technical scheme of the present invention is as follows:
A low-grade gold collecting agent, is characterized in that being made by the raw material of following weight portion: sulphur nitrogen nitrile ester 30-34, alkyl xanthogenic acid acrylonitrile ester 10-12, butyl ammonium aerofloat 10-12, NaOH 1-2, styryl phosphonic acid 17-19,4-hydroxy butyl vinyl ether 3-4, potassium bichromate 1-2, sodium metasilicate 2-3, two phenethyls multiple phenol polyethenoxy ether 2-3, polyoxyethylene oleic acid ester 1-2,2-fluoroacetic acid base fourth are led sour 5-7, activator 10-12;
Described activator is made by the raw material of following weight portion: sodium lignin sulfonate 2-3, silane resin acceptor kh-550 1-2, neopelex 2-3, sodium phosphate trimer 1-2, dimethicone 4-5, polyacrylic acid 2-3, HPMA 3-4, water 40-50; Its preparation method is that each raw material is mixed, and is heated to 60-65 ℃, stirs 45-60 minute, obtains.
The preparation method of described low-grade gold collecting agent, it is characterized in that: other composition except activating agent and NaOH is mixed, at 45-50 ℃, under 8000-12000 rev/min, stir 10-15 minute, add again activator and NaOH, under 6000-8000 rev/min, stir 15-30 minute and get final product.
Beneficial effect of the present invention
Collecting agent of the present invention has the double action of collecting and foaming, foam stabilization, and collecting ability is strong, makes the gold mine rate of recovery high, and selectively good, gold ore grade is high; The activator of the application of the invention, changes gold mine surface hydrophobic, and activation internal structure, has improved collecting agent to golden collecting performance, for the gold mine of low taste, can bring into play its characteristic, has the high rate of recovery, and gold is of high grade.
The specific embodiment
A low-grade gold collecting agent, by following weight portion (kilogram) raw material make: the multiple phenol polyethenoxy ether 2.5 of sulphur nitrogen nitrile ester 32, alkyl xanthogenic acid acrylonitrile ester 11, butyl ammonium aerofloat 11, NaOH 1.5, styryl phosphonic acid 18,4-hydroxy butyl vinyl ether 3.5, potassium bichromate 1.5, sodium metasilicate 2.5, two phenethyls, polyoxyethylene oleic acid ester 1.5,2-fluoroacetic acid base fourth are led acid 6, activator 11;
Described activator by following weight portion (kilogram) raw material make: sodium lignin sulfonate 2.5, silane resin acceptor kh-550 1.5, neopelex 2.5, sodium phosphate trimer 1.5, dimethicone 4.5, polyacrylic acid 2.5, HPMA 3.5, water 45; Its preparation method is that each raw material is mixed, and is heated to 63 ℃, stirs 50 minutes, obtains.
The preparation method of described low-grade gold collecting agent is, other composition except activating agent and NaOH is mixed, and at 48 ℃, stirs 13 minutes under 11000 revs/min, then adds activator and NaOH, stirs 18 minutes and get final product under 7000 revs/min.
Experimental data
When the carbonaceous quartzite type gold ore of head grade 3.80g/t is carried out to flotation, while using this collecting agent, the thick gold mine productive rate of Au is 15.36%, the thick gold ore grade 20.10g/t of Au, the Au rate of recovery 81.26%.
