Abstract
The invention discloses a gold ore collecting agent. The gold ore collecting agent comprises, by weight, 30-34 parts of hydroximic acid, 10-12 parts of O (oxygen)-alkyl-N (nitrogen)-alkyl sulfide carbamate, 24-27 parts of oleic acid, 2-4 parts of sodium carbonate, 3-4 parts of sodium silicate, 24-27 parts of 1,3-dimethyl butyl xanthate, 1-2 parts of trichloroisocyanuric acid, 12-14 parts of black powder, 4-6 parts of butyl sulfone propylene, 2-3 parts of DL-2-hydroxy sodium butyrate and 10-12 parts of activator. The gold ore collecting agent has collecting and foaming functions, stable foam and high collecting capability, so that gold ore recovery rate is high, selectively is good, and gold ore grade is high; through the activator, surface hydrophobicity of gold ore is changed, internal structure of the gold ore is activated, gold collecting performance of the collecting agent is improved, good recovery rate is guaranteed for various gold ores difficult to separate, and gold ore grade is high.
Description
Technical field
The present invention relates to mineral floating technical field, particularly a kind of gold mine 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 gold mine collecting agent and preparation method thereof, this collecting agent has collecting and foaming double attribute, and selectively good, collecting ability is strong, the advantage that recovery rate in ore-dressing is high.
Technical scheme of the present invention is as follows:
A kind of gold mine collecting agent, it is characterized in that being made by the raw material of following weight portion: hydroximic acid 30-34, O-alkyl-N-alkyl sulfide is by carbamate 10-12, oleic acid 24-27, sodium carbonate 2-4, sodium metasilicate 3-4,1 3-dimethylbutyl xanthate 24-27, sym-closene 1-2, black powder 12-14, fourth yellow acid propylene 4-6, DL-2-hydroxyl base butyric acid sodium salt 2-3, 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 gold mine collecting agent, is characterized in that: other composition except activating agent is mixed, at 45-50 ℃, stir 10-15 minute under 8000-12000 rev/min, then add activator, stir 15-30 minute and get final product under 6000-8000 rev/min.
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, and the gold mine of various difficult choosings is all had to the good rate of recovery, and gold is of high grade.
The specific embodiment
A kind of gold mine collecting agent, by following weight portion (kilogram) raw material make: hydroximic acid 32, O-alkyl-N-alkyl sulfide be by carbamate 11, oleic acid 25, sodium carbonate 3, sodium metasilicate 3.5,1,3-dimethylbutyl xanthate 25, sym-closene 1.5, black powder 13, fourth yellow acid propylene 5, DL-2-hydroxyl base butyric acid sodium salt 2.5, 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 gold mine collecting agent is, other composition except activating agent is mixed, and at 48 ℃, stirs 13 minutes under 10000 revs/min, then adds activator, stirs 25 minutes and get final product under 7000 revs/min.
Experimental data
When the carbonaceous quartzite type gold ore of head grade 4.80g/t is carried out to flotation, while using this collecting agent, the thick gold mine productive rate of Au is 19.20%, the thick gold ore grade 20.70g/t of Au, the Au rate of recovery 85.80%.
Comparative example
When the carbonaceous quartzite type 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 19.14%, the thick gold ore grade 19.99g/t of Au, the Au rate of recovery 79.71%.
The collecting agent collecting ability of finding out the embodiment of the present invention from above data is strong, selectively good.
