Description
Technical field
The present invention relates to a kind of mineral flotation foaming agent, and in particular to one kind is prepared using Utilize Cyclohexane Oxidation By-Product X oil
Mineral flotation foaming agent, be particularly well-suited to the flotation of the mineral such as metal sulfide, metal oxide ore or nonmetallic ore, belong to ore deposit
Thing flotation preparation technique field.
Background technology
During cyclohexane oxidation preparing cyclohexanone and Hexalin, X is oily to have a kind of by-product to be referred to as, and its output accounts for ring
The 5%～8% of hexanone yield.Due to the development of China's chinlon chemical fibre industry, the volume of production of Ketohexamethylene expands rapidly, every year up to 10
Ten thousand more than t, side-product X oil yields are big.X oil outward appearances are brownish black thick liquid, are burnt mainly as fuel at present, range of application
Narrower, also there is the patent that some are utilized with regard to X oil the country, but fewer, and such as patent CN104177218A discloses one kind from ring
The method that key component is reclaimed during hexanone by-product-X is oily, including pretreatment, hydrogenation, hydrolysis and often-part of rectification under vacuum four,
Recycling process is complex.If the comprehensive utilization of X oil can be realized, its added value of product is improved, no matter from environmental angle
Or economic benefit angle has great significance.
Worldwide most of mineral resources useful constituent comparision contents are low, it is necessary to process ability through mineral resources
Improve its useful constituent content and later use in addition, flotation is again most widely used side in mineral resources processing technique field
Method.Floatation frother is one of most important floating agent in the mineral resources course of processing, in order that valuable mineral and stone-like pulse ore deposit
Thing is efficiently separated, and is often required to produce a large amount of foams using foaming agent, forms a large amount of gas-liquid interfaces, makes valuable mineral be enriched in gas-liquid
Interface is floated and is separated with stone-like pulse, and the impact of the performance of foaming agent to floatation indicators is very notable.Foaming agent is usually polarity
Surfactant, contains in the molecular structure polar group, hydrophilic entrance liquid phase, such as hydroxyl, carboxyl, ether, molecule
The other end is non-polar group, and close gas enters gas phase, such as alkyl, so that foaming agent molecule produces orientation on gas-liquid interface
Arrangement.Foreign countries are methyl isobutyl carbinol (MIBC) using more extensive floatation frother.MIBC is contracted by raw material of acetone
Close, due to the restriction of current domestic production technology, substantially based on import, price is higher, constrains MIBC in state
Interior application.The foaming agent species of China's synthetic is fewer, and the terpene compound-pine refined from Oleum Pini is used always
There are many defects in oleyl alcohol, terpineol foaming agent, from the point of view of floatation process feature, the inclined medium size of foam that terpineol is produced,
Microvesicle is less, is unfavorable for the attachment of particulate ore deposit, and the particulate response rate is low.Meanwhile, terpineol abnormal smells from the patient is very big, affects health, with
The terpineol of tailings discharging, biological degradability is poor, has pollution to aquatic organism and environment.
The research aspect of new foaming agent, has both at home and abroad substantial amounts of report.Chinese patent CN1403206A disclose by
Branched alcohol and oxirane or expoxy propane ratio dispensing on request, and add the alkali of material quantity gross weight 0.3%～1%
The oxide of metal K, Na makees catalyst, anti-at a temperature of 0.01～1.2MPa pressure, 170～190 DEG C in autoclave
Normal pressure is depressured to after answering 2～3 hours, less than 50 DEG C are cooled to, the method for foaming agent is filtrated to get.Chinese patent
CN102614994A is disclosed with monohydric alcohol and polyhydric alcohol as raw material, in the presence of catalyst 70～90 DEG C in inert environments
Reaction 1～3 hour, is down to after room temperature and adjusts product pH value to the neutral method for obtaining foaming agent.Chinese patent
CN103721854A is disclosed with n-butyl alcohol (C4H10O) as the main foaming agent of flotation, tetraethylene glycol (TEG) (C8H18O5) it is auxiliary blowing agent
Method.
So far, the foaming agent for adopting in mineral processing production practice is still based on terpenic oil and MIBC.Terpenic oil is derived from
Natural plants, complicated component, the active constituent content of common pinitol oil product is only 50% or so.And MIBC is expensive, no
Beneficial to popularization and application.Therefore, X oil is modified and is applied to floatation frother, be expected to promote the recycling of X oil and rise
The development of infusion.
The content of the invention
For the defect that prior art is present, it is that a kind of foams performance of offer is good, abnormal smells from the patient is low, peace that the purpose of the present invention is
The mineral flotation foaming agent that loopful is protected.
It is to provide that a kind of raw material sources are wide, low cost, simple to operate, process conditions temperature that another object of the present invention is
The method for preparing the mineral flotation foaming agent of sum.
It is the application for providing a kind of mineral flotation foaming agent in mineral floating that third object of the present invention is, it has
Have the advantages that frothing capacity is good, consumption is few, abnormal smells from the patient is low, be particularly adapted to metal sulfide, metal oxide ore or nonmetallic ore
