Abstract
The invention discloses a collecting agent for copper and gold ores. The collecting agent comprises, by weight, 20-23 parts of diltiazem nitrile ester, 20-23 parts of ammonium dibutyl dithiophosphate, 3-5 parts of naphthenic acid, 2-3 parts of oxidized paraffin soap, 3-4 parts of sodium dodecyl benzene sulfonate, 1-2 parts of sodium napthionate, 3-4 parts of sodium oleate, 3-4 parts of sodium fluoride, 7-9 parts of O-alkyl-N-alkyl sulfide thionic carbamate, 6-9 parts of dimethylglyoxime and 10-12 parts of activator. The collecting agent has the advantages that collecting and foaming effects can be realized by the collecting agent, foams are stable, the collecting agent is high in collecting capacity, gold ores are high in recovery rate, selectivity and grade, a copper suppressing effect can be realized, and copper can be prevented from being collected; owing to the activator, surface hydrophobic properties of the gold ores can be changed, internal structures of the gold ores can be activated, the gold collection performance of the collecting agent can be improved, and gold is high in recovery rate and grade.
Description
Technical field
The present invention relates to mineral floating technical field, particularly collecting agent and preparation method thereof for a kind of cuproaurite.
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 collecting agent and preparation method thereof for a kind of cuproaurite, this collecting agent has selectively good, the advantage that collecting ability is strong.
Technical scheme of the present invention is as follows:
A cuproaurite collecting agent, is characterized in that being made by the raw material of following weight portion: sulphur nitrogen nitrile ester 20-23, butyl ammonium aerofloat 20-23, aphthenic acids 3-5, oxidized paraffin wax soap 2-3, neopelex 3-4, sodium naphthenate 1-2, enuatrol 3-4, sodium fluoride 3-4, O-alkyl-N-alkyl sulfide are by carbamate 7-9, dimethylglyoxime 6-9, 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 collecting agent for described cuproaurite, it is characterized in that: other composition except activating agent is mixed, at 45-50 ℃, stir 10-15 minute under 10000-12000 rev/min, add again activator, under 6000-8000 rev/min, stir 20-30 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, copper is had to inhibitory action simultaneously, can collecting copper; 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, and gold recovery is high, of high grade.
The specific embodiment
A cuproaurite collecting agent, by following weight portion (kilogram) raw material make: sulphur nitrogen nitrile ester 22, butyl ammonium aerofloat 22, aphthenic acids 4, oxidized paraffin wax soap 2.5, neopelex 3.5, sodium naphthenate 1.5, enuatrol 3.5, sodium fluoride 3.5, O-alkyl-N-alkyl sulfide are by carbamate 8, dimethylglyoxime 7, 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.
Described cuproaurite by the preparation method of collecting agent is: other composition except activating agent is mixed, at 48 ℃, stir 13 minutes under 11000 revs/min, then add activator, stir 25 minutes and get final product under 7000 revs/min.
Experimental data
When the copper-gold ore of head grade 6.70g/t is carried out to flotation, while using this collecting agent, the thick gold mine productive rate of Au is 26.44%, the thick gold ore grade 21.02g/t of Au, the Au rate of recovery 82.96%.
Comparative example
When the copper-gold ore of identical grade in specific embodiment is carried out to flotation, use butyl xanthate and QF combination, the thick gold mine productive rate of Au is 26.65%, the thick gold ore grade 20.78g/t of Au, the Au rate of recovery 76.65%.
The collecting agent collecting ability of finding out the embodiment of the present invention from above data is strong.
