Row, which is raised, to be sent；
Step 2: molybdic tailing slurry is delivered to flat cone cyclone and is classified, and molybdic tailing slurry, will be less than 120 mesh by classification
Sand grains and thin mud raised by flat cone cyclone overflow central tube into Tailings Dam settlement on storage；The sand grains of 120 mesh be will be greater than by flat cone
Cyclone underflow enters high-frequency oscillation dewatering screen；
Step 3: by dehydration high frequency shale shaker after dehydration, sand grains up to standard is transported to through closing conveyer belt on sieve
Product stacks library and carries out stockpiling sale, sieves lower waste water slurry and enters the clarification of Tailings Dam settlement on storage；
Step 4: all Tailings Dam clarified wastewaters that enter return to dressing plant's multiplexing.
Of the invention is further described, five plunger reciprocating pump is positive displacement pump, have flow is constant, run smoothly,
Fluid power pulsation is few, is suitble to the Tailings transportation of long range, Gao Yangcheng.
Of the invention is further described, the sand grains that upper sand grains up to standard is moisture content 20% is sieved in the step 3.
By adopting the above technical scheme, it has the following beneficial effects:
Configuration process of the present invention by five plunger reciprocating pumps, flat cone cyclone and high-frequency oscillation dewatering screen, Neng Gouyou
Effect ground recycles sub-sand grain in the middle part of tailing, reaches ultra fine sand standard applied to construction market and reduces CHARACTERISTICS OF TAILINGS SAND to place
It occupies and ecological environment destruction purpose, meets that the high lift of tailing, long-distance delivery, weight feed classification, yield is controllable, energy
In dressing plant end according to feelings flexible configuration feature, comprehensive utilization of tailing rate can be effectively improved, the discharge of gangue solids is reduced,
The disturbance improved the ecological environment alleviates the demand in building aggregate market, can obtain good economic and social profit, has mine
The meaning that mountain industry promotes and applies, the size of scale of the present invention is adjustable, but flowage structure and principle are constant.
Detailed description of the invention
Fig. 1 is process structure schematic diagram of the invention；
Fig. 2 is device connection diagram of the invention.
Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
Embodiment 1: a kind of method that ultra fine sand is recycled from molybdic tailing as shown in Fig. 1 to Fig. 2, including following step
It is rapid:
Step 1: molybdic tailing slurry focus in tailings pump pond, by five plunger reciprocating pumps by conveyance conduit by pressurize into
Row, which is raised, to be sent；
Step 2: molybdic tailing slurry is delivered to flat cone cyclone and is classified, and molybdic tailing slurry, will be less than 120 mesh by classification
Sand grains and thin mud raised by flat cone cyclone overflow central tube into Tailings Dam settlement on storage；The sand grains of 120 mesh be will be greater than by flat cone
Cyclone underflow enters high-frequency oscillation dewatering screen；
Step 3: by dehydration high frequency shale shaker after dehydration, sand grains up to standard is transported to through closing conveyer belt on sieve
Product stacks library and carries out stockpiling sale, sieves lower waste water slurry and enters the clarification of Tailings Dam settlement on storage；
Step 4: all Tailings Dam clarified wastewaters that enter return to dressing plant's multiplexing.
Five plunger reciprocating pump is positive displacement pump, has that flow is constant, run smoothly, fluid power pulsation is few, be suitble to over long distances,
The Tailings transportation of high lift, the upper sand grains up to standard of sieve is the sand grains of moisture content 20% in the step 3.
Dressing plant's molybdic tailing starches dry tailing amount such as 3000t/d, converts into 125t/h；Tailing specific gravity: by 2.7 designs, tailing
Granularmetric composition and yield: less than 80 mesh contents account for 9.02%, account for 20.25% less than 120 mesh contents greater than 80, are less than greater than 120
200 mesh contents account for 16.27%, account for 23.04% less than 400 mesh contents greater than 200, account for 31.42% greater than 400 mesh contents；Tailing
Concentration: 27-33% can output building materials ultra fine sand 1000t/d less than the sand grains of 120 mesh in centralized recovery tailing.
Through the invention by five plunger reciprocating pumps+flat cone cyclone+high-frequency dewatering screen configuration process, Neng Gouyou
Effect ground recycles sub-sand grain in the middle part of tailing, reaches ultra fine sand standard applied to construction market and reduces CHARACTERISTICS OF TAILINGS SAND to place
