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 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 containing golden zincblende capture reagent for gold and preparation method thereof, this collecting agent has selective good, the advantage that collecting ability is strong.
Technical scheme of the present invention is as follows:
A kind of containing golden zincblende capture reagent for gold, it is characterized in that being made up of 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, oxine 3-5, 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 described preparation method containing golden zincblende capture reagent for gold, it is characterized in that: by other composition mixing except activating agent, at 45-50 DEG C, under 8000-9000 rev/min, stir 10-15 minute, add activator again, stir under 5000-7000 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, and strong to golden collecting ability, make the gold mine rate of recovery high, to Zn, Fe not collecting, 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; Be applicable to choosing gold in zincblende or marmatite.
