Abstract
A kind of refractory gold ore collecting agent, is made up of the raw material of following weight portion: butyl xanthate 23-27, sodium naphthalene sulfonate 3-4, pyrophosphoric acid 4-6, oleic acid 35-38, sodium thiosulfate 4-5, vulcanized sodium 1-2, isopropoxyethyl radicals thiourethane 16-18, triethyl citrate 4-6, sodium ethyl xanthate 6-8, benzothiazole mercaptan 12-14, gluconic acid 3-4, activator 10-12; Collecting agent of the present invention has the double action of collecting and foaming, foam stabilization, and collecting ability is strong, and make the gold mine rate of recovery high, selective good, gold ore grade is high; The activator of the application of the invention, changes gold mine surface hydrophobic, and activation internal structure, improves the collecting performance of collecting agent to gold, and all have the good rate of recovery to the gold mine of various difficulty choosing, environmental pollution is little, and collecting agent reclaims easily.
Description
Technical field
The present invention relates to mineral floating technical field, particularly a kind of refractory gold ore 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 gold recovering mineral.The collecting agent of better collecting effect is had to have puratized agricultural spray black powder, butyl ammonium aerofloat, catch the floating agents such as Jin Ling, Y-89, M16, QF to gold mineral at present, the collecting ability of conventional flotation medicament to gold mine is stronger, but it is selective poor, the problem that to also exist that gold recovery is low, index fluctuates large, flotation effect is undesirable, the problem that resource utilization is low.
In recent years, the research application that is novel, efficient combination floating agent carried out around improving golden mineral processing index achieves greater advance.Especially the most outstanding to change surname medicament in the investigation and application of new and effective medicament.Medicament modification comprises: introduce in existing medicament and can improve and strengthen the force of reagents and mineral surfaces other active group interactional; Develop individual water-soluble chelating or complexation agent; Select to have different activities and function two kinds and various medicaments combination and mixed reagent.Although the research of gold ore flotation medicament achieves significant progress, but still understand because partially carbonized thing adsorpting formulation in floatation process, or other reason, cause the loss to a certain degree of gold, gold mine samples the problem differed, and causes damage to enterprise and society.
Summary of the invention
The object of this invention is to provide a kind of refractory gold ore collecting agent and preparation method thereof, this collecting agent has collecting and foaming double attribute, selective good, and collecting ability is strong, beneficiation enrichment ratio, the advantage that recovery rate in ore-dressing is high.
Technical scheme of the present invention is as follows:
A kind of refractory gold ore collecting agent, is characterized in that being made up of the raw material of following weight portion: butyl xanthate 23-27, sodium naphthalene sulfonate 3-4, pyrophosphoric acid 4-6, oleic acid 35-38, sodium thiosulfate 4-5, vulcanized sodium 1-2, isopropoxyethyl radicals thiourethane 16-18, triethyl citrate 4-6, sodium ethyl xanthate 6-8, benzothiazole mercaptan 12-14, gluconic acid 3-4, activator 10-12;
Described activator is made up of 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 mixed by each raw material, is heated to 60-65 DEG C, stirs 45-60 minute, to obtain final product.
The preparation method of described refractory gold ore collecting agent, it is characterized in that: by other composition mixing except activating agent, at 45-50 DEG C, under 10000-12000 rev/min, stir 10-15 minute, add activator again, stir under 6000-8000 rev/min 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, and make the gold mine rate of recovery high, selective good, gold ore grade is high; The activator of the application of the invention, changes gold mine surface hydrophobic, and activation internal structure, improves the collecting performance of collecting agent to gold, and all have the good rate of recovery to the gold mine of various difficulty choosing, environmental pollution is little, and collecting agent reclaims easily.
Detailed description of the invention

Described activator is made up of the raw material of following weight portion (kilogram): 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 mixed by each raw material, is heated to 63 DEG C, stirs 50 minutes, to obtain final product.
The preparation method of described refractory gold ore collecting agent is: by other composition mixing except activating agent, at 48 DEG C, stir 13 minutes, then add activator under 11000 revs/min, stir 25 minutes and get final product under 7000 revs/min.
Experimental data
When carrying out flotation to the carbonaceous quartzite type gold ore of head grade 3.60g/t, when using this collecting agent, Au thick gold mine productive rate is 14.61%, thick gold ore grade 20.13g/t, Au rate of recovery 81.72% of Au.
Comparative example
When carrying out flotation to the carbonaceous quartzite type gold ore of grade identical in specific embodiment, use butyl xanthate and QF combination, Au thick gold mine productive rate is 14.61%, thick gold ore grade 19.78g/t, Au rate of recovery 76.30% of Au.
Find out that the collecting agent collecting ability of the embodiment of the present invention is strong, selective good from above data.
