Description
Technical field
The present invention relates to technical field of beneficiation, in particular to the system of a kind of scheelite and gangue mineral FLOTATION SEPARATION inhibitor
Preparation Method and application.
Background technique
From sulphide ore, black tungsten, white tungsten, fluorite, calcite symbiosis complex multi-metal mine in flotation black and white tungsten ore, this kind of mine
Stone FLOTATION SEPARATION is relatively difficult, is all utilized in inhibition fluorite, calcite in strongly basic medium both at home and abroad at present, uses fatty acid
Ore, i.e., be ground to after the granularity of requirement and first floatingly select vulcanization by the method for collecting agent (Oxidized paraffin wax or oleic acid) Scheelite Flotation mine
Mine, flotation black and white tungsten (or Scheelite Flotation), general method are the addition sodium carbonate 1000 into ore pulp to sulfide flotation tailing again
G ton or more, addition waterglass inhibits fluorite, calcite and other gangue minerals, does collecting using Oxidized paraffin wax or oleic acid
Agent flotation black and white tungsten (or Scheelite Flotation).China Hunan persimmon bamboo plantation polymetallic ore is one large-scale tungsten, molybdenum, bismuth, fluorite symbiosis
Complex multi-metal mine.Major metal mineral have scheelite, wolframite, bismuthine, molybdenite, magnetic iron ore, pyrite etc., main arteries and veins
Stone ore object is garnet, quartz, fluorite, calcite, pyroxene, hornblend etc..Raw ore contains tungstic acid 0.56%, wherein 2/3 is
Scheelite, 1/3 is wolframite.Raw ore contains 0.09% bismuth-containing 0.18% of molybdenum, calcium fluoride containing 18-20%.Current ore-dressing technique stream
Cheng Shi：After raw ore is milled to the fineness that -200 mesh account for 85%, first Flotation of Sulfide Ores respectively obtains molybdenum concentrate, bismuth concentrate and iron concentrate.
Sulfide flotation tailing carries out tungsten flotation, and the floating agent used is：Sodium carbonate, waterglass, Oxidized paraffin wax, flotation pulp pH
Value is 10-11, after slurry pH is adjusted to 9 or so with sulfuric acid by tungsten flotation tailing, then with fatty acid collecting agent flotation fluorite.It is existing
Floatation major defect is：The flotation recovery effect of black and white tungsten ore is poor, generally also to add before or after tungsten flotation operation
Reselection operation (spiral concentrator and shaking table) recycles wolframite.Keep process flow complicated, while the flotation recovery after tungsten flotation
When fluorite, it is also necessary to which slurry pH is transferred to 9 or so by the sulfuric acid of 600-1000 g tons of reagent removal or addition, not only increases medicament expense
With, and the floatation indicators of fluorite are also poor.
A kind of beneficiation method of Flotation of Sulfide Ores recycling black and white tungsten first from complex multi-metal mine of CN95117062.7,
Invention is characterized in that the method from the tailing flotation of tungsten after Flotation of Sulfide Ores is：A. 250-500 g tons of sodium metasilicate, carboxylic are added
It 20-40 g tons of methylcellulose, stirs 2-5 minutes；B. 800-1200 g tons of plumbi nitras is added, nitrito- phenylhydroxylamine amine is added
It 500-800 g tons of ammonium salt, stirs 6-10 minutes；C. 2-12 g tons of oleic acid of addition emulsification, is stirred 2-5 minutes；D. thick through 1 time
Choosing, 2 times it is selected, scan for 2 times, obtain tungsten rough concentrate.
Summary of the invention

The carboxymethyl cellulose for weighing 3.5g pours into 100ml three-necked flask, is subsequently added into the detergent alkylate sulphur of 4.2g
Acyl chlorides, then the n,N-Dimethylformamide (DMF) for using graduated cylinder to measure 40ml are poured into flask as solvent, and 0.3g is and then added
Pyridine solution as acid binding agent.After putting up device, recirculated water is opened,；Start agitating and heating.60 DEG C are warming up to, when reaction
Between be 4 hours.It cools down to after reaction, reaction product is put into stand on one side, is then slowly fallen while stirring with stirring rod
Enter in the beaker equipped with 200ml dehydrated alcohol, there is pale yellow precipitate.Then suction filtration separation is carried out using bottle,suction, finally used
Baking oven, which is adjusted to 70 DEG C, dries product, weighs, and obtains the modified carboxymethyl cellulose of dodecyl benzene sulfonyl chloride, and degree of substitution is
0.579。
The modified carboxymethyl cellulose performance characterization of 3 dodecyl benzene sulfonyl chloride of embodiment
Infrared spectrum measurement
Using Bruker Fourier transformation infrared spectrometer (model：VERTEX 70), sample is detected using KBr pressed disc method
It is in 400~4000cm-1Infrared spectrogram, at room temperature (25 DEG C), humidity 50% detect.
By modified carboxy methyl cellulose take it is micro be put into agate Yan Portland, potassium bromide is added and is ground, until be ground into
Powder.Later by pressed powder, be pressed into it is thin and transparent after be just put among instrument, carry out the detection of infrared spectroscopy.
Degree of substitution refers to the average number replaced dodecyl benzene sulfonyl chloride on each Aglycone of carboxymethyl cellulose,
According to the infared spectrum of the carboxymethyl cellulose after modification, being acquired using integral in characteristic peak is 2926.35cm-1The long-chain at place
Alkyl vibration peak and characteristic peak are 1038.56cm-1The area ratio at the C-O key chattering peak at place, i.e. A2926.35/A1038.56。
3 dodecyl benzene sulfonyl chloride modified carboxy methyl cellulose (being abbreviated as SDS-CMC) of embodiment can float three kinds of mineral
The research of property
The separation of scheelite and fluorite, Calcite by Flotation process mainly comprises the following steps, and is fluorite and side by main gangue mineral
It after the scheelite of Xie Shi is levigate, is added in flotation device and stirs, sodium hydroxide is added and adjusts slurry pH, the suppression of the preparation is added
Preparation, 20mg/L finally add collecting agent enuatrol 30mg/L, are carrying out flotation.
It is 120mg/L that Fig. 1, which show test collecting agent enuatrol dosage, and pH value is controlled 10 ± 0.2.Data can from figure
To obtain, for scheelite substantially not by the inhibiting effect of SDS-CMC, the rate of recovery is 90% or so, is held essentially constant；Calcite exists
SDS-CMC dosage starts when being 4-8mg/L by strong inhibition, and the rate of recovery reduces rapidly, and is down to 1.05% from 79.28%, it
Calcite, which is constantly in, afterwards is totally constrained；Fluorite with the dosage of SDS-CMC increase, the rate of recovery with reduction, from
71.35% is down to 29.71%.
Fig. 2 is SDS-CMC as inhibitor, and when enuatrol is as collecting agent, slurry pH is to three kinds of mineral floatabilities
Research.At inhibitor SDS-CMC dosage 10mg/L, the flotation conditions of collecting agent enuatrol dosage 120mg/L, SDS-CMC exists
There is stronger inhibiting effect to calcite and fluorite under soda acid (pH=6-12) ore pulp environment, especially to calcite inhibitory effect
Preferably, the rate of recovery is all very low；Preferable than alkaline environment in acidic environment to the inhibitory effect of fluorite, fluorite returns before pH=8
Yield increases with pH and amount of increase is little, and when pH is before 8-10, Fluorite recovery rate goes up suddenly, is risen to by 46.65%
68.79%；And SDS-CMC does not have inhibiting effect to scheelite, and the rate of recovery of scheelite, white tungsten can be improved to a certain extent
The mine rate of recovery rises as pH increases, and the rate of recovery is increased to 88.65% from 63.87%.
4 dodecyl benzene sulfonyl chloride modified carboxy methyl cellulose of embodiment (abbreviation SDS-CMC) composite ore float test
