Abstract
From Copper sulfide ore containing gold, select a flotation agent for gold, be made up of the raw material of following weight portion: butyl xanthate 36-39, carboxymethyl cellulose 2-3, n-butanol 20-24, phosphoric acid fourth fat 3-4, oleic acid 6-8, sulphur nitrogen nitrile ester 8-10, isopropoxyethyl radicals thiourethane 14-16, salicylic acid 1-2, sodium thiocarbonate 2-3, ethylenediamine tetra-acetic acid 2-3, citric acid 3-5, glycolic acid 10-12, activator 10-12; It is strong that flotation agent of the present invention has collecting ability, and make the gold mine rate of recovery high, selective good, gold ore grade is high; The activator of the application of the invention, activated ore internal structure, improves the collecting performance of collecting agent to gold, all has the good rate of recovery to the gold mine of various difficulty choosing, is particularly useful for choosing gold in copper-sulphide ores.
Description
Technical field
The present invention relates to mineral floating technical field, particularly a kind of flotation agent and preparation method thereof selecting gold from Copper sulfide ore containing gold.
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 flotation agent and preparation method thereof selecting gold from Copper sulfide ore containing gold, this flotation agent has collecting and foaming double attribute, selective good, the advantage that collecting ability is strong.
Technical scheme of the present invention is as follows:
From Copper sulfide ore containing gold, select a flotation agent for gold, it is characterized in that being made up of the raw material of following weight portion: butyl xanthate 36-39, carboxymethyl cellulose 2-3, n-butanol 20-24, phosphoric acid fourth fat 3-4, oleic acid 6-8, sulphur nitrogen nitrile ester 8-10, isopropoxyethyl radicals thiourethane 14-16, salicylic acid 1-2, sodium thiocarbonate 2-3, ethylenediamine tetra-acetic acid 2-3, citric acid 3-5, glycolic acid 10-12, 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 selecting the flotation agent of gold from Copper sulfide ore containing gold, it is characterized in that: by other composition mixing except activating agent, at 50-60 DEG C, under 9000-11000 rev/min, stir 10-15 minute, add activator again, stir under 6000-8000 rev/min 15-30 minute and get final product.
Beneficial effect of the present invention
It is strong that flotation agent of the present invention has collecting ability, and make the gold mine rate of recovery high, selective good, gold ore grade is high; The activator of the application of the invention, activated ore internal structure, improves the collecting performance of collecting agent to gold, all has the good rate of recovery to the gold mine of various difficulty choosing, is particularly useful for choosing gold in copper-sulphide ores.
