Description
Technical field
The present invention relates to copper nickel sulfide mineral flotation auxiliary material technical fields, and in particular to one kind is applied to low-grade vulcanization cupro-nickel
High-efficient collecting agent of mine and preparation method thereof.
Background technique
With deepening continuously for exploitation, copper-nickel sulfide property tends to be poor miscellaneous, and cupro-nickel ore dressing difficulty increases, bulk concentrate quality
Not high, the target minreal rate of recovery is low, and association rare precious metal synthetical recovery is difficult.Conventional xanthate class, black powder class (such as butyl xanthate,
Isoamyl xanthate and butylamine black powder etc.) collecting agent is although all kinds of many and preferable to the simple copper-nickel sulfide effect of ore properties,
But the copper nickel effect serious to argillization, head grade is low is general, especially thin to raw ore cupro-nickel mineral disseminated grain size, ore
The mineral of matter complexity, sorting result are worse.Therefore, the beneficiation reagent of screening efficiently, economic, environmentally friendly is comprehensive to valuable mineral is solved
The problems such as rate of recovery is low, and reagent cost is high is of great significance.
Summary of the invention
The technical problem to be solved in the present invention is to provide one kind to have both collecting and bubbling character, to the low-grade copper sulfide of rich magnesium
Nickel minerals selectivity is preferable, collecting effect is obvious, and flotation froth size, color, gloss, intensity are relatively stable, bubble mineralization degree
Well, mineral ascent rate is fast, can be improved low grade copper-nickel sulphide ores object concentrate grade and the rate of recovery high-efficient collecting agent and its
Preparation method.
In order to solve the above technical problems, the present invention adopts the following technical scheme: a kind of be applied to low grade copper-nickel sulphide ores
High-efficient collecting agent, i.e. RL-08 collecting agent, it is characterised in that: by weight, raw material composition is as follows:
30-50 parts of isoamyl xanthate
10-30 parts of amine alcohol xanthate
10-30 parts of fourth Sodium Aerofloat
5-15 parts of diphenylguanidine
5-15 parts of methyl isobutyl carbinol.
Preferably, by weight, raw material composition is as follows:
40 parts of isoamyl xanthate
20 parts of amine alcohol xanthate
20 parts of fourth Sodium Aerofloat
10 parts of diphenylguanidine
10 parts of methyl isobutyl carbinol.
Further, the collecting agent is optimal applied to the nickeliferous vulcanization ambrose alloy for being lower than 0.42%, cupric and being lower than 0.13%
Nickel mineral has preferable collecting effect for the nickel sulfide cupro-nickel mineral of this grade.
A kind of preparation method of the high-efficient collecting agent applied to low grade copper-nickel sulphide ores, it is characterised in that: normal in room temperature
Pressure, 30-50 parts of isoamyl xanthate, 10-30 parts of amine alcohol xanthate, 10-30 parts of fourth Sodium Aerofloat, 5-15 parts of diphenylguanidine, methyl is different
5-15 parts of butyl carbinol sequentially add in stirred tank, are stirred 0.5-1 hours at room temperature to get the low-grade vulcanization cupro-nickel
The high-efficient collecting agent of mine.
The present invention determines the parts by weight range of raw material composition and each component by a large number of experiments, so that each raw material can be sufficiently
Respective synergistic effect is played, avoids traditional xanthate class, black powder class collecting agent with butyl xanthate, isoamyl xanthate and butylamine black powder
Deng be used as primary raw material, lead to the disadvantage of the sorting result difference of copper nickel serious to argillization, that head grade is low.To make this hair
It is bright to have the following advantages that, 1, have both collecting and bubbling character, to rich magnesium low grade copper-nickel sulphide ores selectivity preferably, collecting effect
Obviously；2, flotation froth size, color, gloss, intensity are relatively stable, and bubble mineralization degree is good；3, mineral ascent rate is fast,
Concentrate grade and the cupro-nickel rate of recovery can be effectively improved.
Specific embodiment
The present invention will be further described combined with specific embodiments below: in the examples below, describing five kinds of raw materials
Parts by weight variation the case where, the method for preparing collecting agent is constant.But it should be noted that the proportion of collecting agent each component is pressed
Weight percent should be it is adjustable in range, specifically isoamyl xanthate 30-50 parts, 10-30 parts of amine alcohol xanthate, fourth sodium it is black
10-30 parts of medicine, 5-15 parts of diphenylguanidine, 5-15 parts of methyl isobutyl carbinol.
It is as follows as five specific Application Examples, i.e., shown in table 1,
Embodiment 1,35 parts of isoamyl xanthate, 30 parts of amine alcohol xanthate, 25 parts of fourth Sodium Aerofloat, 5 parts of diphenylguanidine, methyl-isobutyl
5 parts of methanol；
Embodiment 2,40 parts of isoamyl xanthate, 20 parts of amine alcohol xanthate, 20 parts of fourth Sodium Aerofloat, 10 parts of diphenylguanidine, methyl tert-butyl
10 parts of base methanol；

Medicine, amine alcohol xanthate, fourth Sodium Aerofloat part, diphenylguanidine part, methyl isobutyl carbinol part are added in stirred tank, and it is small to be stirred 0.5-1
When, it is added in stirred tank, is stirred at room temperature 30 minutes, 45 minutes, 50 minutes or 1 hour by the weight specified in table 1, make
?.Then beneficiation test is carried out to Low-grade Cu-ni Ore with the collecting agent.
In order to more intuitively describe influence of the parts by weight of raw materials variation to mineral processing index in different embodiments, in the same terms
It is lower that single Copper Ores is selected to carry out beneficiation test, the grade and the rate of recovery of copper, nickel rough concentrate are listed respectively, it is coarse-fine by copper, nickel
The performance of the collecting agent of the variation reflection different material parts by weight synthesis of mine mineral processing index.
Raw ore nickel grade used in embodiment and comparative example beneficiation test is 0.42%, copper grade 0.13%.
Parts by weight of raw materials variation specific value is shown in Table 1, comparative example beneficiation test specific value and is shown in Table 2.
Table 1
Table 2
Copper, nickel ore concentrate grade are high, illustrate that the selection performance of collecting agent is strong；Copper, the rate of recovery of nickel rough concentrate are high, illustrate collecting
Agent collecting performance is strong.
The above has been described in detail, described above, is only a preferred embodiment of the present invention, when cannot
Limit the application practical range, i.e., it is all according to the made equivalent changes and modifications of the application range, it should still belong to covering scope of the present invention
It is interior.
