Description
Technical field
The present invention relates to flotation technology field, particularly relates to a kind of refractory oxidized copper ore flotation synergist.
Background technology
Increasing to the demand of copper with China's rapid development of economy, this will make the disparities between supply and demand of China's copper resource
It is more and more prominent.From the point of view of world's copper resource, each Copper Mine there are about 10%~15% oxide ore.China's copper resource is enriched, its
Middle oxidation ore reserves, which is more about, accounts for 1/4.In addition to most of mineral deposits are all there are oxidized zone, there is large-scale cupric oxide mineral deposit to exist.
These cupric oxide ores mostly have the spies such as oxygenation efficiency is high, clay content is big, particulate misproportion dissemination, oxygen sulphur mix, thickness mixing
Point, very low plus the cupric oxide ore cupric having, this just determines the difficulty of cupric oxide ore ore dressing.The main mine of cupric oxide ore
Species type has malachite, chrysocolla, chessy copper, cuprite, black copper ore, blue stone, warringtonite and atacamite etc..Conventional flotation oxygen
The method for changing copper has been difficult to adapt to the needs of current complicated refractory copper oxide, and new medicament, new process, joint flotation flowsheet are more next
More become the development side of flotation refractory copper oxide.Copper oxide mineral floatability is poor, is difficult to obtain ideal using conventional flotation medicament
Sorting result, therefore focus on synthesis and the profit of new and effective medicament for the Oxidized copper ores of cupric oxide ore in recent years
With.
The new Chelating Collectors B-130 of Sichuan nonferrous metallurgy Research Institute has been successfully applied to the difficult choosing oxidation of Tonglushan Mine
The processing of copper mine, its mechanism of action are mainly that can make that the sulfide film of mineral surfaces is quick, absorption is caught securely in floatation process
Agent is received, improves the flotation speed and flotation efficiency of refractory copper oxide mineral.2,5- dithiol -1 of Kunming Inst. of Metallurgy research and development,
3- thio biphospholes are a kind of organic activators of cupric oxide ore, it is soluble in KOH or NaOH aqueous solutions, are slightly soluble in the ethanol of heat.
Lijiang, yunnan cupric oxide ore is sand shape oxide ore, raw ore copper grade 2.02%, oxygenation efficiency 79.24%, with traditional medicament
Vulcanized sodium is compared, and uses D2(2,5- dithiol -1,3- thio biphospholes) can obtain grade 22.63%, the copper of the rate of recovery 81.67%
Concentrate, in the case where concentrate grade is suitable, copper, silver raising recovery rate all improve 2~3 percentage points.Shenyang Research Institute of Nonferrous Metals
Develop a kind of novel oxidized copper mineral collecting agent OK2033.Chen Xinlin, Liu Xuesheng etc. carry out ore dressing examination using OK2033 to it
Test, the results showed that, roughing can obtain the copper rough concentrate of grade 8.43%, the rate of recovery 72.93%, make collecting compared to hydroximic acid
Agent, the roughing rate of recovery improve more than 1.5 percentage points, and copper rough concentrate grade also improves nearly 1 percentage point.Having research, this is carried
A kind of collecting agent with the cupric oxide ore compared with high selectivity is gone out, copper grade can be obtained by carrying out float test using the collecting agent
15.8%, the copper concentrate (patent No. of the rate of recovery 91.5%：CN 103464302A).
Although the research report on the new floating agent of refractory copper oxide ore is very much, it is concentrated mainly on cupric oxide ore and catches
The research and development field of agent is received, the relevant report of development and application for flotation synergist is few.Synergist one kind, which has, necessarily catches
Agent performance is received, but does not play collecting agent in floatation process, a small amount of addition is remarkably improved the surface-active of floatation indicators
Agent.Common synergist is mainly some nonionic surface active agent.Collector modified and mixed reagent is to improve collecting agent
The common method of performance, fatty acid collecting agent are used in mixed way existing numerous studies and practice with synergist.
At present, in terms of the research of the new floating agent of refractory copper oxide ore is concentrated mainly on collecting agent, flotation synergist
Using being also concentrated mainly on the mineral such as fluorite, apatite and bauxite, and for the research of refractory copper oxide ore flotation synergist
Report less.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of refractory oxidized copper ore flotation synergist, can significantly carry
High its sorts recovery index, has the features such as stability is good, and good water solubility, activity is high, adaptable, and dosing is few.
Synergist composition of raw materials parts by weight composition is as follows：60 parts of 8-hydroxyquinoline, 45 parts of dioctylphosphoric acid ester, ammonium sulfate 15
Part, 5 parts of kerosene, 5 parts of ethanol.
The preparation method of the synergist, comprises the following steps that：

Liquid phosphoric acid dioctyl ester, kerosene and ethanol are mixed again, obtain liquid pharmaceutical solution；
Then, powder-mixed solid is added in the liquid pharmaceutical solution mixed, adds water to be configured to volume
Fraction is the solution of 30%-35%；
Finally, the solution prepared is placed in microwave field and is handled, 40 DEG C~50 DEG C of heating-up temperature, mixing time 15
~20min, obtains synergist.
Wherein, microwave field strength 0.5-2kW.
The synergist of the present invention for being remarkably improved refractory copper oxide ore floatation indicators is a kind of composite surface activity
Agent, the application method of synergist are that the flotation confection stoste prepared according to the method described above is directly made an addition to grinding operation,
Make medicament come into full contact with the ball mill with mineral to play a role.
The above-mentioned technical proposal of the present invention has the beneficial effect that：
In such scheme, synergist be it is a kind of by the floating agent that forms of various medicaments compounding, institute's medicament stock that uses for
General chemistry industrial products, raw material sources extensively, be easy to get, use rear non-environmental-pollution and degradable.Microwave intervention medicament adds
Temperature mixing, by using the strong microwave absorbing property of hydrone, makes hydrone absorb microwave energy in microwave field and is changed into high-energy, by force
The molecule of hydration, realizes the heating of a variety of floating agents under the fuel factor of microwave radiation and the collective effect of non-thermal effect
Fusion, improves the reactivity of floating agent.Synergist can directly make an addition to grinding operation in the form of stoste, without specially adjusting
PH value, less dosage is remarkably improved floatation indicators, while reduces flotation collector dosage, for the suitable of refractory copper oxide ore
Answering property is good.The advantages that stability is good in addition, the synergist also has, good water solubility, activity is high.The new medicament of the present invention is used for oxygen
Change the floatation process of copper mine, significant effect, has obvious technology economy advantage and environmental benefit.
