Abstract
A collecting agent for separating gold from auriferous sphalerite is prepared by the following raw materials in part by weight: 18-20 parts of sodium nonyl xanthate, 4-7 parts of diethyl dithiocarbamate, 3-4 parts of aluminum sulfate, 3-5 parts of ferrous sulfate, 12-15 parts of alkyl succinic acid ester sulfonate, 12-14 parts of n-caprylic alcohol, 1-2 parts of carboxymethylcellulose, 2-3 parts of phenyl ethyl isopropyl phenyl phenol polyoxyethylene ether, 12-14 parts of benzoquinone dioxime, 3-5 parts of 8- hydroxyquinoline and 10-12 parts of activating agents. The collecting agent has a collecting function and a foaming function; the gold collecting ability is high, so that the recycling rate of gold ores is high; the collecting agent does not collect Zn and Fe, the selectivity is high, and the grade of the gold ores is also high; and moreover, by using the activating agents, the surface hydrophobicity of the gold ores is changed, the internal structure is activated, and the gold collecting performance of the collecting agent is improved. The collecting agent is applicable to sphalerite or is applicable to separating gold from the sphalerite.
Description
Technical field
The present invention relates to mineral floating technical field, particularly a kind of containing golden zincblende capture reagent for gold 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 golden zincblende capture reagent for gold and preparation method thereof that contains, this collecting agent has selectively good, the advantage that collecting ability is strong.
Technical scheme of the present invention is as follows:
Containing a golden zincblende capture reagent for gold, it is characterized in that being made by the raw material of following weight portion: nonyl sodium xanthogenate 18-20, diethyldithiocarbamate 4-7, aluminum sulfate 3-4, ferrous sulfate 3-5, dialkyl succinylsuccinate ester sodium sulfonate 12-15, n-octyl alcohol 12-14, carboxymethyl cellulose 1-2, phenethyl cumenyl phenol polyethenoxy ether 2-3, parabenzoquinone dioxime 12-14,8-oxyquinoline 3-5, activator 10-12;

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 described preparation method containing golden zincblende capture reagent for gold is: other composition except activating agent is mixed, at 47 ℃, stir 13 minutes under 8500 revs/min, then add activator, stir 25 minutes and get final product under 6000 revs/min.
Experimental data
To head grade 4.80g/t containing golden zincblende stone while carrying out flotation, while using this collecting agent, the thick gold mine productive rate of Au is 19.02%, the thick gold ore grade 20.70g/t of Au, the Au rate of recovery 82.02%.
Comparative example
To identical grade in specific embodiment containing golden zincblende stone, while carrying out flotation, use butyl xanthate and QF combination, the thick gold mine productive rate of Au is 18.97%, the thick gold ore grade 20.57g/t of Au, the Au rate of recovery 77.30%.
