Abstract
The invention discloses a kind of column machines rapidly and efficiently to select zinc method, sweeps flotation flowsheet using thick 2 essences of flotation device 1+thick 1 essence of flotation column 1+flotation device 3.First with flotation device by well it is floating, compared with the quick output of coarse granule zinc, recycle flotation column by medium difficult floating zinc in the selected middle output of flotation column, the zinc floating to hardly possible, output is cooperateed in flotation column again with collecting effect by activation for a long time in flotation device, both the flotation time and process of floating zinc mineral are shortened, reduce middling cycle loss, and difficult floating zinc mineral is allowed to have more time and chance to float.Not only having well solved same mineral has different floatabilities, and it solves the problems, such as size fractionated zinc mineral there are different floatabilities, fining is realized to sort, significantly improve zinc recovery, it realizes and efficiently selects zinc, raising zinc recovery and concentrate quality, energy-saving, clean manufacturing are had a very important significance.
Description
Technical field
The present invention relates to a kind of beneficiation method and systems, and in particular to a kind of column machine rapidly and efficiently select zinc method and
System.
Background technique
Led-zinc-silver deposit is the important mineral resources in China, and existing lead zinc nonferrous mine nearly thousand, how golden mainly lead zinc is
Belong to sulphide ore, for the grade of general zinc compared with lead height, income from sales of the zinc in lead-zinc sulfide ore exploitation typically constitutes from 60% or more.Zinc essence
Mine is the primary raw material for producing metallic zinc, zinc compound etc..The ore dressing time how made good use of limited zn Mineral resource, improve zinc
Yield either enterprise or country are all particularly important.
In lead zinc nonferrous metal mine, traditional floatation process of the current zinc flotation in China be 1 roughing+3-4 scan+
2-3 selected successively sequence Returning process, the lead zinc floatation equipment overwhelming majority are applied successfully using flotation device, flotation column
Seldom.Traditional floatation process method is difficult to further increase zinc recovery rate in ore-dressing and concentrate grade, and resource recovery is caused to mention
The problems such as height is difficult, and equipment multipotency consumption is high, reagent consumption is high, causes beneficiation cost high, while serious there is also flotation spill-over.
The technology of the present invention selects zinc to combine floatation process using column machine (flotation device+flotation column+flotation device), is floated using a small amount of
Machine is selected to select quick output to enter product fastly in zinc most of well floating, that particle is thicker zinc mineral；Recycle flotation column pair
The features such as flotation of particulate zinc mineral is favorably and treating capacity is big, not spill-over, big concentration ratio, the medium difficult zinc floated is passed through in flotation column
1 thick 1 it is selected enter product；The floating zinc of hardly possible is acted on by scavenging flotation machine activation for a long time with collecting, it is complete that zinc scans operation foam
Portion directly returns to zinc flotation column roughing, enters product by the collaboration output that can be floated between mineral in flotation column；Both it shortened
The flotation time and process of floating zinc mineral reduce middling cycle loss, and difficult floating zinc mineral is allowed to have more time and chance
It floats.The technology is applicable not only to lead-zinc polymetallic sulfide ore zinc flotation, is also applied for the floating of other nonferrous metals ore sulphide ores
Choosing.The exploitation of the technology of the present invention, has adapted to the needs of industry technology development, and technological achievement has extensive popularization and application foreground.
The inventive technique provides fine technical support and demonstration with comprehensive utilization for zn Mineral in polymetallic ore mountain is resource-effective, to rush
Into China's metal mine technical progress of industry, Resources for construction economizing type, environmentally friendly modernization mine have great promotion
Effect will make bigger contribution for China's mining industry Efficient Development and comprehensive utilization.

Beneficial effects of the present invention are as follows:
(1) it in the case where selecting Zn system using column machine combined mineral dressing technology, selects zinc to do using thick 2 essence of flotation device 1 and selects+float fastly
It selects thick 1 essence of column 1+flotation device 3 times to scan process flow, realizes that column machine process is combined and select zinc, break traditional flotation: flotation device choosing
Not, the process equipment process that flotation column+flotation device sorts, flotation column sorts.
(2) 3 foams scanned of flotation device are directly selected with zinc fastly and enters flotation column roughing operation together with tailing, break biography
The way that order of floatation of uniting returns.
(3) be conducive to coarse granule zinc mineral using flotation device to float, flotation column is more advantageous to fine grained zinc mineral floating
Feature, the zinc mineral good compared with thick, floatability to particle are directly entered zinc concentrate product by the 1 thick fast choosing of 2 essence when zinc selects fastly；It is right
Particle is relatively thin, floatability slightly almost select tailing zinc mineral to progress greatly in column flotation by 1 thick 1 fastly to produce into zinc concentrate
Product；It is again introduced into flotation column for scanning the poor zinc mineral of floatability in foam, and by the synergistic effect between mineral, makes it
There are more times to float.
(4) it scans middle zinc to sweep 2, sweep the foam of 3 operations, breaks traditional handicraft and sort, no longer carry out sequence return, but will
Select zinc scan operation foam and zinc fastly thick tailing, directly return to the roughing operation of zinc flotation column together with zinc column essence tailing, shortening can
The flotation time of floating zinc mineral, has given full play to flotation column: being more advantageous to that fine grained floats, treating capacity is big, does not overflow, concentration ratio
High feature reduces loss of the zinc in middling cycle, alleviates the internal circulating load for scanning operation, extend flotation time, subtract
Lack zinc and run tail, improves zinc recovery.
(5) it selects zinc to scan foam and is directly entered flotation column roughing, chats amount and flotation pulp amount substantially reduce, dosing
Also it decreases, solves the problems, such as the frequent spill-over of flotation device, it is reliable convenient to operate, and process is smooth.It is straight together that zinc scans foam
Return roughing is connect, is not returned successively, water supplement substantially reduces, and the ore pulp amount of zinc flotation can be reduced, and dosing also drops therewith
It is low, reduce the circulation ore pulp amount for scanning operation, improve floatation concentration, extend flotation time, reduces zinc in zinc tail
Loss, realize and rapidly and efficiently select zinc, improve the comprehensive resource utilization rate of Zn-containing sulfide ore, increase economic benefit.
In short, the invention proposes a kind of new to select zinc technology flow high efficiency beneficiation method, by the flotation of column machine joint,
Zinc quickly is selected, foam is scanned and is returned directly to the thick operation of zinc, realizes the collaboration essence to different grain size, different floatability zinc minerals
Flotation is refined, middling cycle is effectively reduced, saves and add water and beneficiation reagent dosage, solves the viscous appearance of zinc flotation froth
The problem of easy spill-over, process is smooth, convenient for operation, significantly improves zinc concentrate recycling and concentrate grade, realization is rapidly and efficiently selected
Zinc.
