Description
Technical field
The invention belongs to Ore Dressing Engineering fields, and in particular to a kind of combination for flotation olive pyroxenite type ilmenite is caught
Receive agent and preparation method and application.
Background technique
With the rapid development of China's titanium industry and the emergence of titanium dioxide industry, China to the demand of ilmenite concentrate increasingly
Greatly.The maximum ferrotianium ore-rock mine mineral deposit in China Sichuan Panxi Diqu, but the titanomagnetite resource of this area pass through tens
The exploitation in year, major part mine has entered medium and deep exploitation at present.Climb the big mining area in Xisi (Panzhihua, red lattice, Baima, Taihe county) more
Toward deep mining, gabbro, pyroxenic ratio are gradually decreased, and the ratio of olive pyroxenite, peridotite gradually increases.This kind of olive brightness
Containing a large amount of gangue minerals such as olivine, titanaugite, chlorite and hornblend etc. in lithotype titanomagnetite, mineral composition is complicated.
Simultaneously because these gangue minerals are similar to valuable mineral ilmenite floatability, they are floated using traditional floating agent
Choosing, poor selectivity, the rate of recovery are low, it is difficult to obtain preferable industrial mineral processing index.
Although some collecting agents for common ilmenite are successfully developed, these collecting agents or it is difficult to obtain
Compared with high-grade ilmenite concentrate or when obtaining compared with high-grade ilmenite concentrate (45% or more), the rate of recovery is lower.In addition, these collectings
The preparation system of agent is excessively complicated, often needs emulsifier, and dosing is larger.The collecting agent announced such as 105583084 A of CN
Preparation system it is complicated, and need a large amount of environmentally harmful lye, the rate of recovery of the collecting agent of the patent is lower, is no more than
82%；If 104971826 A of the CN collecting agent announced not only prepares system complexity, and the rate of recovery is only more than 60%；Such as CN
The collecting agent that 102489410 B are announced not only prepares system complexity, and in order to obtain higher grade and the rate of recovery, need to be in floating sulphur
It is operated afterwards using thick three essence, process is more many and diverse；System is not only prepared such as 104117435 A of the CN collecting agent announced to answer
Miscellaneous, concentration times need more than three times and the rate of recovery is lower；Although although the collecting agent that 102600985 A of CN is provided prepares system
It is relatively simple, concentrate grade and lower sulfuric acid dosage are slightly improved in ore dressing, but its rate of recovery is still very low.
It is worth noting that the product of the type mineral raw ore are also resided in for the difficulty of olive pyroxenite type ilmenite ore dressing at present
Position is usually lower, and generally 17~18%, how low-grade ore is subjected to ore dressing and obtains high-grade concentrate, is the difficulty of this field
One of topic.
Summary of the invention
In view of the shortcomings of the prior art, one of the objects of the present invention is to provide one kind to be used for flotation olive pyroxenite type ilmenite
Combined capturing and collecting agent, which is made of component A, component B and water, wherein component A is oleic acid or oxidized paraffin wax soap,
Component B is primary amine salt or quaternary ammonium salt；
Wherein, the weight ratio of component A and component B are weight of the sum of the weight of 9:1~12:1, component A and component B with water
Weight ratio be 1:4~19；
The head grade of the olive pyroxenite type ilmenite is not higher than 18%.
The primary amine salt includes dodecylamine hydrochloride or tetradecy lamine hydrochloride.
The quaternary ammonium salt includes decyl trimethyl ammonium chloride or dodecyl trimethyl ammonium chloride.
Preferably, the component A is oleic acid.
Preferably, the component B is dodecylamine hydrochloride.
As a preferred embodiment of the invention, the component A is oleic acid, and the component B is dodecylamine hydrochloride.
The weight ratio of oleic acid and dodecylamine hydrochloride is 10:1.
Another object of the present invention is that providing the method for preparation said combination collecting agent, the method are as follows:
Component A and component B is mixed by the weight relationships, then water is added by the weight relationships, at 40 DEG C~60 DEG C
Under the conditions of constant temperature water bath, stir 20~30 minutes to get.
Another object of the present invention is that providing said combination collecting agent in terms of flotation olive pyroxenite type ilmenite
Using.
It is described in application, the flotation pulp that combined capturing and collecting agent uses pH range be 5.0~10.0, flotation temperature 10
~25 DEG C, the dosage of combined capturing and collecting agent is 1800~2200g/t raw ore.
Beneficial effects of the present invention:
Combined capturing and collecting agent of the invention is applied to have good floatation indicators (concentrate product when the ilmenite flotation of olive pyroxenite type
Position is up to 46% or more, and the rate of recovery is up to 86% or more), and while reaching above-mentioned floatation indicators required concentration times are only 2 times, the present invention
The dosing of about one third or so can be reduced.Collecting agent of the present invention requires flotation conditions loose simultaneously, and has preferable
Stability in hard water.
Detailed description of the invention
Fig. 1 is flotation process figure of the invention.
