Abstract
The invention belongs to the technical field of mineral processing processes and mainly relates to a process for floatation of high-concentration scheelite rough concentrate. The grade of the scheelite rough concentrate is about 1.3%, the pulp concentration of a heating barrel is above 65%, the specification of the heating barrel is phi 5.0 m*5.5 m, the ore pulp height is 3.0 m, a reagent removal agent is added through calculation according to unit consumption of the rough concentration of 65 kg/t, and under the high-temperature stirring condition, quartz, fluorite, silicate and other gangue minerals are effectively separated from scheelite. After the ore pulp heating reagent removal process is completed, ore pulp is added with clean water to be distilled to 35%-40% in concentration to enter concentration work, an air inflow valve of a flotation machine is properly opened slightly, it is guaranteed that the ore pulp liquid level is stable in floatation work, scheelite particles and the gangue minerals can be effectively separated within short time, the scheelite particles can quickly be gathered on the surfaces of bubbles and then scraped out accordingly, and then the scheelite rough concentrate is obtained. The ore pulp floatation time is basically within 2.0 hours, finally the grade of the scheelite rough concentrate is still kept about 30%, and the recovery rate is still above 96%.
Description
Technical field
The invention belongs to mineral processing technology field, relate generally to the technique of the white tungsten rough concentrate of a kind of flotation high concentration.
Background technology
Luanchuan molybdenum ore belongs to molybdenum tungsten many metals associated minerals, white tungsten resource rich reserves.Molybdenum plant tailing enters Bai Wuxuan factory and carries out white tungsten resource synthetical recovery.Within 2008, white tungsten ore dressing plant initial design disposal ability is 6000t/d, white tungsten head grade about 0.05%, and along with Mu Xuan factory treatment scale constantly expands, present disposal ability has reached 15200t/d, white tungsten head grade about 0.095% scale.In earlier stage white tungsten is roughly selected process section and is changed to three current series by inner transformation by original two serial expansions, substantially can meet the needs roughly selecting production technology at present.And white tungsten dressing process section flow process remains the flow process of design when founding the factory, rough concentrate treating capacity is increased to present about 800t/d by about the 200t/d of 2008.Rough concentrate amount increases severely, and cause φ 30 meters of serious overload operations of concentrator, selected job throughput wretched insufficiency, causes selected operation cannot meet normal production.
Summary of the invention
For overcoming the deficiency in background technology, the object of this invention is to provide a kind of technique of high concentration Scheelite Flotation rough concentrate, to reach when equipment, technology and production index remain unchanged, increase selected job throughput, alleviate φ 30 meters of concentrator pressure and ensure the object that selected operation is normally produced.
Object of the present invention can adopt following technical scheme to realize:
A technique for the white tungsten rough concentrate of flotation high concentration, its preparation process is:
(1) choose the white tungsten rough concentrate of taste 1.3%, after roughly selecting, obtain the ore pulp of more than 65% after concentrated, send into through Pulp pump and heat in agitator, sampling detects pulp density;
(2) to warming up pulp, add NaOH when being warmed to 60 DEG C, then be warmed to 85 DEG C, then add reagent removal agent TY-1, continue to heat to 95 DEG C, then stop heating;
(3), after being incubated 1 hour at 95 DEG C, the rough concentrate passing through reagent removal of heating enters an agitator and sizes mixing, and makes pulp density carry out flotation operation at 35-40%;
(4), after temperature reduces, every barrel of warming up pulp time foreshortened to 1.1 hours by 1.5 hours, and selected operation recovery remains on more than 96%, and wet concentrate grade remains on about 30%.
In described step (1), after sampling detects pulp density, calculate this barrel of ore pulp according to pulp density and do ore deposit amount,
Do ore deposit amount by ore pulp when being warmed to 50 DEG C in step (2) and add NaOH, when being warmed to 75 DEG C, doing ore deposit amount according to ore pulp and add reagent removal agent TY-1.
Described thermal barrel specification is φ 5.0 × 5.5m, and ore pulp height is 3.0m.
The interpolation unit consumption of described reagent removal agent TY-1 is the amount of 65kg/t rough concentrate.
The specification of described agitator is φ 2.0 × 2.0m.
In described step (3), the normal flotation time of agitator every barrel is 3.5-4.0 hours.
Owing to adopting technical scheme as above, the present invention has following superiority:
De-unit consumption of medicine is increased to about 65kg/t by 60kg/t.Its objective is when rough concentrate amount is constant, increase de-dosing, be conducive under high-temperature stirring condition, strengthen better inhibitory action of gangue mineral such as quartz, fluorite, silicates, make these gangue minerals can better be suppressed, reach and just make scheelite effectively be separated with gangue mineral heating in reagent removal process.Slurry dilution to 35% after having heated-40%, enter selected operation, and suitably littlely open flotation device air intake valve, guarantee that flotation operation mineral syrup liquid is steady, white tungsten particle just can be made effectively to be separated with the gangue mineral short time, white tungsten particle can be enriched in bubble surface very soon, and scrapes thereupon, obtains white tungsten fine ore.The flotation of ore pulp time, final white tungsten fine ore grade still remained on about 30%, and the rate of recovery is still more than 96% substantially within 2.0 hours.
Be selected in concentration by improving white tungsten rough concentrate, selected job throughput increases by more than 1 times, significantly improves selected operating efficiency, has saved equipment operating cost and power consumption simultaneously, alleviates selected operational pressure, ensure that the normal operation of production.
Key of the present invention is according to rough concentrate grade, suitably increases de-unit consumption of medicine, ore pulp is effectively suppressed at most of gangue mineral in whipping process of heating.Selected concentration remains on 35%-40%, and like this in floatation process, scheelite does not need the enrichment long time just can reach grade and the rate of recovery of expection.If selected concentration is too low, selected operation foam will be caused excessively empty, then the rate of recovery significantly glides.
Detailed description of the invention
A technique for the white tungsten rough concentrate of flotation high concentration, its preparation process is:
