Description
Technical field
The present invention relates to a kind of method of smithsonite type zinc oxide ore flotation desilication, and in particular to smithsonite and quartz
Flotation separation method, belong to Mineral Processing Engineering field mineral floating separation technology field.
Background technology
The consumption figure of zinc resource is number three in non-ferrous metal, is number four in metal.Zinc is in dry external condition
Under relatively stable, and surface easily one layer of fine and close zinc carbonate film of generation under humid conditions, therefore can be to other materials table
Face is handled.Current most of zinc metal is applied in zinc-plated industry.In addition zinc rubber, battery, shielding material, pigment,
The industry such as printing, paint are also widely used.In recent years, with the rapid growth of China's economic, need of the China for zinc resource
The amount of asking also increases.In 2014, China's zinc concentrate import volume reached 219.82 ten thousand tons.Therefore, the ore dressing of zinc ore is improved
Sustainable development of the index to zinc resource has great importance.
Smithsonite is a kind of important mineral in zinc resource.At present floatation be the most important recovery method of smithsonite it
One.But because smithsonite is more crisp, therefore easily produces sludge in grinding process and be unfavorable for the sorting of valuable mineral and increase medicine
Agent usage amount.In addition smithsonite is a kind of carbonate mineral in itself, and easily dissolving produces zinc ion to silicate arteries and veins in ore pulp
Stone ore produce life-stylize effect, thus using fatty acid collecting agent also can collecting silicate gangue mineral, so as to cause concentrate
Grade is not high.Sulfidization-amine method is the most commonly used method for floating at present.But both need to add activator in floatation process to water chestnut
Zinc ore, which is activated, will also add inhibitor the gangue minerals such as quartz are suppressed, so as to cause flotation flowsheet i.e. complicated and difficult
With control.Therefore probing into new smithsonite ore floatation process, the rate of recovery for improving smithsonite provide with grade to China's zinc
Efficiently utilizing for source is significant.
The content of the invention
The present invention provides a kind of method of smithsonite type zinc oxide ore flotation drop silicon, and main purpose is according to new collecting
Agent realizes the effective of mineral to smithsonite and the different flotation behaviors of gangue mineral quartz by adding suitable regulator
Sorting.This method technological process and regime of agent are simple, and can realize the target of smithsonite ore floatation drop silicon.
A kind of method of smithsonite type zinc oxide ore flotation desilication, methods described include following processing steps：
(1) it is 1 in mass ratio by pending sample ore and water：3~5 mixing, size mixing 1~3min；Alternatively, into ore pulp
Add pH regulators to adjust slurry pH to 10~12, then size mixing 2~3min again；
(2) collecting agent N, N '-bis- fatty acyl groups ethylene diamine dipropionic acid sodium, stirring are added into ore pulp obtained by step (1)
2min, wherein, the dosage of the collecting agent is 300~360g/t；Afterwards by add collecting agent flowsheet of slurry agitation it is uniform after floated
Choosing, 3~5min of flotation time.
In the method for smithsonite type zinc oxide ore flotation desilication of the present invention, in step (1), by pending sample ore
It is 1 in mass ratio with water：3~5 mixing, size mixing 1~3min；The then pH value of measurement gained ore pulp, as ore pulp pH value determination is
Required slurry pH, then directly carry out step (2)；If ore pulp pH value determination is not the pH value of required ore pulp, then adjusted using pH
Agent adjusts slurry pH to required slurry pH, and then size mixing 2~3min again.
Above-mentioned " required slurry pH " can be 10~12 in arbitrary value, it can artificially be limited, in order to investigate and
Obtain the flotation results under condition of different pH.
In above-mentioned technical proposal, described " dosage of collecting agent refers to the pending sample ore institutes of every 1t for 300~360g/t "
It is 300~360g with the amount of collecting agent.
Product i.e. mine tailing in flotation froth product i.e. concentrate and groove is respectively dried after further, flotation terminates, weighed,
Calculate the rate of recovery and chemically examine grade.
In above-mentioned technical proposal, preferably pending sample ore be smithsonite with quartz artificial mixed ore, and smithsonite with
The mass ratio of quartz is 3:17.
In above-mentioned technical proposal, preferably it is described size mixing for：Ore pulp is stirred with 1600~1992r/min stir speed (S.S.)
Mix.
In above-mentioned technical proposal, preferably described pH adjuster is Na2CO3Solution.The method of the invention is to described
Na2CO3Solution has no particular/special requirement.
Compared with traditional method for floating, the beneficial effect of this method is：Smithsonite type zinc oxide ore proposed by the present invention
The method regime of agent of stone flotation desilication is simple, only need to add collecting agent N, N '-bis- fatty acyl groups ethylene diamine dipropionic acid sodium and pH
It is worth regulator Na2CO3The target of smithsonite ore floatation drop silicon can be achieved, thus it is easy to operate, there is well industrial feasible
Property.
