Description
Technical field
The present invention relates to the technical fields of ore dressing, the in particular to technical field of copper-cobalt ore flotation.
Background technique
It is different using the physics of different minerals, chemical property in ore dressing process, the flotation from grind grading overflow pulp
The enrichment process of different types of mineral is referred to as flotation out, keeps the various mineral of levigate ore effective in flotation operation
Separation, it is often necessary to pass through chemicals treatment, so that part mineral is floated after processing, and other mineral are stayed in ore pulp, by
This reaches the process of separation and enrichment.The flotation of single is extremely difficult to be totally separated from effect, therefore in actual production, mineral
Separation would generally by roughing, multiple processes, these processes such as scan, be selected can be in a manner of whole selective flotations, can also
It is realized in a manner of through other ore dressings.If all using the mode of flotation, because of the property and main component of ore pulp in various process
The content floating agent that may have occurred that variation, therefore use can be performed in accordance with adjustment.
Various medicaments used in floatation process, collectively referred to as floating agent remove collecting agent and are risen in floating agent
Outside infusion, referred to as floatation regulator, to reach good flotation effect, floatation regulator in the prior art is typically more multiple
It is miscellaneous, include a variety of constituents such as pH adjusting agent, activator, inhibitor, dispersing agent, flocculant.
It is the complexity for reducing floatation regulator in portion of techniques, has only selected a kind of or two, three kind of substance as flotation
Regulator, but need to improve its dosage simultaneously, lead to the rising of production cost.
Summary of the invention
It is an object of the invention to the copper-molybdenums that is applied to for proposing that a kind of dosage is few, flotation efficiency is high, flotation quality is good to vulcanize
Floatation regulator in mine separating flotation, another object of the present invention is to propose the application method of the floatation regulator.
Technical scheme is as follows:
A kind of floatation regulator applied in copper-molybdenum sulphide ore separating flotation, for vulcanized sodium is dissolved in Drinking Water
Obtained in mixed liquor.
In the technical solution, the effects of vulcanized sodium can play inhibitor, reagent removal agent, activator, pH adjusting agent simultaneously, due to
The native floatability of molybdenite is preferable, and vulcanized sodium is small to its inhibition, therefore it presses down copper effect very in copper, molybdenum separating flotation
It is excellent.
The mode that flotation is carried out after mixing the prior art mainly adopts production return water with floating agent, under this form,
The flotation efficiency of vulcanized sodium is low, and flotation capacity is poor, and system pH, which deviates from vulcanized sodium, can use the range that play a role of effect, and
System pH stability is poor in floatation process, and system distribution of charges is unstable, leads to flotation poor controllability, the concentrate grade floatingly selected
Not high enough, stability of floatation is poor.Drinking Water is used in this programme, can effectively be solved these problems, so that less
Under amount of sodium sulfide, the concentrate grade floatingly selected 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 applied to the floatation regulator in copper-molybdenum sulphide ore separating flotation
Method, in the floatation regulator to be applied to the roughing of copper-molybdenum bulk concentrate, scans, is selected.
Its preferred embodiment are as follows: every kilogram of mineral use the 8 ~ 20g of floatation regulator.
Its another preferred embodiment are as follows: in floatation regulator used in the roughing concentration of vulcanized sodium be 18 ~
20wt%。
It is further preferred that floatation regulator used in the roughing is first handled through energization using preceding, be powered electricity
Pressure is less than 1.7V, and conduction time is 0.5 ~ 1h.
Its another preferred embodiment are as follows: it is described scan used in floatation regulator the concentration of vulcanized sodium be 15 ~
17wt%。
It is further preferred that it is described scan used in floatation regulator first handled through energization using preceding, be powered electricity
Pressure is less than 1.5V, and conduction time is 0.5 ~ 1h.

14wt%。
It is further preferred that it is described it is selected used in floatation regulator first handled through energization using preceding, be powered electricity
Pressure is less than 1V, and conduction time is 0.5 ~ 1h.
It, generally can be by following Ionization Equation after vulcanized sodium itself ionizes in aqueous solution in floatation regulator of the invention
Formula generates HS-、S2-、Na+、OH-Plasma:
Discovery is investigated in the broad range of pH=6 ~ 12, certain sulfurization can be played, show HS-And S2-From
Son can play sulfurization for mineral, if the pH of control system is relatively relatively low, until S2-The content of ion is lower than HS-Content
When, adsorbance and adsorption rate of the sulphur on sulfide mineral surface are all higher at this time, show HS in the case-Ion ratio S2-
Ion has higher sulfurate activity, while OH at this time-The absorption competition ability of ion is weaker, can become HS-Ionic adsorption in
Favorable factor on mineral surfaces, the present invention in by using Drinking Water as solvent, be formulated as flotation tune with vulcanized sodium
Whole dose, the first purpose is to reach and maintains such pH state, to improve flotation efficiency and quality.
In the preferred embodiment of application method of the invention, by different flotation stages, such as roughing, scan,
In selected, different energizations is carried out to the floatation regulator of various concentration first and is handled, one of its goals is to adjust in flotation
Agent improves flotation efficiency and flotation quality to maximize using the content of different ions in preceding effective adjustment system.
