Step S300, mine tailing slurry is made to enter pretreatment system, to be cleaned to the mine tailing slurry before magnetic separation.Specifically
For, mine tailing slurry is the Ta Nb tailings after gravity treatment.Mine tailing slurry first passes through Pulp pump 304, subsequently into concentrator
305, after concentrator concentrates current stabilization, straight line shaker 306, after straight line shaker screens, mine tailing slurry are passed through in the underflow of discharge again
Into the first magnetic separator 307 in magnetic separation system.
Step S301, mine tailing slurry is made to enter magnetic separation system, to filter out magnetic material and non-magnetic material.It is specific and
Speech, is screened by the first magnetic separator, the second medicament agitator tank that the magnetic material for screening to obtain enters in floatation system
310；Screen obtained non-magnetic separation material and enter the second magnetic separator 308, the magnetic material that the second magnetic separator screens to obtain enters
Second medicament agitator tank 310 in floatation system；Last second magnetic separator in series connection process screens to obtain non magnetic
The first medicament agitator tank 309 that material enters in floatation system.
Step S302, flotation is carried out respectively to the magnetic material and non-magnetic material that filter out using floatation system.First
The non-magnetic material of medicament agitator tank discharge enters the first flotation device 311 to floatingly select lepidolite and feldspar；Second medicament stirs
The magnetic material of tank discharge enters the second flotation device 312 to floatingly select lepidolite and magnetic mine tailing.Connect process in last
The feldspar that individual first flotation device flotation obtains enters the vacuum tank 313 of product handling system system；In process of connecting last the
The magnetic mine tailing that two flotation device flotation obtain enters the first cyclone 315 of product handling system system；And the lithium obtained by flotation
Mica enters the small concentrator 314 of inclined tube-type of product handling system system.
Step S303, product handling system is carried out to the product after floatation system flotation using product handling system system.Specifically,
After feldspar enters vacuum tank, the second cyclone 316 of product handling system system is entered back into, finally by the first of product handling system system
Feldspar finished product is obtained after belt vacuum filter 319.After magnetic mine tailing enters the first cyclone, then by product handling system system
Dewatering screen 318, you can obtain magnetic mine tailing finished product.After lepidolite enters the small concentrator of inclined tube-type, product handling system system is entered back into
The second belt vacuum filter 317 after, you can obtain lepidolite finished product.
The Ta Nb tailings Comprehensive recycle technology that the utility model embodiment also provides, entered according to the property of ore in itself
Row ore dressing, mineral intergrowth relation complexity, granularity and thinner difficult point are overcome, so as to realize to above-mentioned lepidolite, feldspar powder and magnetic
Effective comprehensive reutilization of property mine tailing.
