Description
Technical field
The present invention relates to the technical field of ore dressing, the more particularly to technical field of copper-cobalt ore flotation.
Background technology
It is different using the physics of different minerals, chemical property in ore dressing process, the flotation from grind grading overflow pulp
Go out the enrichment process referred to as flotation of different types of mineral, be to enable the various mineral of levigate ore effective in flotation operation
Separation, it is often necessary to by chemicals treatment, part mineral is floated after treatment, and other mineral stayed in ore pulp, by
This reaches the process separated with enrichment.The flotation of single is extremely difficult to be totally separated from effect, therefore actual production, mineral
Separate would generally by roughing, scan, multiple processes such as selected, these processes can also may be used in the way of whole selective flotations
Realized with by other ore dressing modes.If all using the mode of flotation, because of the property and main component of ore pulp in various process
Content may have occurred that change, therefore the floating agent for using can accordingly be adjusted.
Various medicaments used in floatation process, collectively referred to as floating agent, remove collecting agent and rise in floating agent
Outside infusion, referred to as floatation regulator, to reach good flotation effect, floatation regulator of the prior art is typically more multiple
It is miscellaneous, comprising various constituents such as pH adjusting agent, activator, inhibitor, dispersant, flocculant.
To reduce the complexity of floatation regulator in portion of techniques, a kind of or two, three kind of material has only been selected as flotation
Regulator, but need to improve its consumption simultaneously, cause the rising of production cost.
The content of the invention
It is an object of the invention to propose that a kind of consumption is few, flotation efficiency is high, the copper-molybdenum that is applied to of flotation quality better vulcanizes
Floatation regulator in ore deposit separating flotation, the application process another object of the present invention is to propose the floatation regulator.
Technical scheme is as follows：
A kind of floatation regulator being applied in copper-molybdenum sulphide ore separating flotation, it is that vulcanized sodium is dissolved in Drinking Water to obtain
The mixed liquor for arriving.
In the technical scheme, vulcanized sodium can simultaneously play the effect such as inhibitor, reagent removal agent, activator, pH adjusting agent, due to
Preferably, vulcanized sodium is small to its inhibition for the native floatability of molybdenite, therefore it presses down copper effect very in copper, molybdenum separating flotation
It is excellent.
It is many by the way of flotation is carried out after production backwater mixes with floating agent in the prior art, under this form,
The flotation efficiency of vulcanized sodium is low, and flotation capacity is poor, and system pH deviate from vulcanized sodium and can use the scope that play a role of effect, and
System pH stability is poor in floatation process, and system distribution of charges is unstable, causes flotation poor controllability, the concentrate grade for floatingly selecting
Not high enough, stability of floatation is poor.Drinking Water is used in this programme, these problems can be effectively solved so that less
Under amount of sodium sulfide, the concentrate grade that floatingly selects is higher, stability of floatation is good.
Preferably：The concentration of vulcanized sodium is 5 ~ 10wt% in the floatation regulator.
Present invention further propose that a kind of application of the floatation regulator being applied in copper-molybdenum sulphide ore separating flotation
Method, be by the floatation regulator be applied to copper-molybdenum bulk concentrate roughing, scan, it is selected in.
It is preferred embodiment：Every kilogram of mineral use the 8 ~ 20g of floatation regulator.
Its is another to be preferred embodiment：In the floatation regulator used in the roughing concentration of vulcanized sodium be 18 ~
20wt%。
Further preferably：The floatation regulator used in the roughing use it is preceding first through energization process, be powered electricity
Pressure is less than 1.7V, and conduction time is 0.5 ~ 1h.
Its is another to be preferred embodiment：The concentration for scanning vulcanized sodium in the middle floatation regulator for using be 15 ~
17wt%。
Further preferably：It is described scan the middle floatation regulator for using use it is preceding first through energization process, be powered electricity
Pressure is less than 1.5V, and conduction time is 0.5 ~ 1h.
Its is another to be preferred embodiment：In the selected middle floatation regulator for using the concentration of vulcanized sodium be 10 ~
14wt%。
Further preferably：The selected middle floatation regulator for using use it is preceding first through energization process, be powered electricity
Pressure is less than 1V, and conduction time is 0.5 ~ 1h.
In floatation regulator of the invention, after vulcanized sodium itself is ionized in aqueous, typically can be by following Ionization Equation
Formula generates HS-、S2-、Na+、OH-Plasma：
Investigate and find in the broad range of pH=6 ~ 12, it can play certain sulfurization, show HS-And S2-Ion pair
Sulfurization can be played in mineral, if the pH of control system is relatively relatively low, to S2-The content of ion is less than HS-Content when,
Now adsorbance and adsorption rate of the sulphur on sulfide mineral surface are all higher, show HS in the case-Ion ratio S2-Ion
With sulfurate activity higher, while now OH-The absorption competition ability of ion is weaker, can turn into HS-Ionic adsorption is in mineral
Favorable factor on surface, floatation regulator is formulated as in the present invention as solvent by using Drinking Water with vulcanized sodium,
It is to reach and maintain this kind of pH states that its first purpose is, to improve flotation efficiency and quality.
In the preferred embodiment of application process of the invention, by different flotation stages, such as roughing, scan,
In selected, the floatation regulator first to various concentrations carries out different energization treatment, and its first purpose is in flotation adjustment
Agent uses the content of different ions in preceding effective adjustment system, so as to maximize raising flotation efficiency and flotation quality.
The present invention possesses following beneficial effect：
（1）Floatation regulator suppression copper effect of the invention substantially, can effectively improve the grade of concentrate after flotation；
（2）Floatation regulator of the invention has suppression copper effect faster, can effectively improve flotation efficiency；
（3）Floatation regulator of the invention has good reagent removal, reactivity, dispersiveness simultaneously, can effectively facilitate collecting agent
And/or the performance of the effect of foaming agent；
（4）Floatation regulator of the invention is relative to the regulator being mixed to get as solvent and vulcanized sodium using production backwater
Speech, can be greatly reduced the consumption of vulcanized sodium.
