Description
Technical field
The present invention relates to a kind of flotation groove face and control method of adjustment, be a kind of mineral floating method, it is adaptable to the technical field of mineral processing of natural ore and people's dressing。
Background technology
In passing on experience work, the apprentices often ask master worker: what method flotation groove face adjustment has？How to adjust？Master worker answers and says: what method flotation groove face adjustment does not have, it is simply that " three are not " does not run that not emit not deep gouge just passable。
About flotation groove face method of adjustment, mineral processing textbook does not have the record of concrete operation method, traditional training materials that each enterprise is self-editing has two kinds of descriptions about flotation groove face method of adjustment:
1, after flotation device starts, the feed valve on flotation device need to repeatedly be regulated, till the foam surface of all flotation devices is in same level in an operation。
2, the foam amount of scraping making each flotation groove face in same flotation region is equal to。
Do not run that not emit not deep gouge be the operation of most basic floor level, pursue foam surface and be in same level, the conventional method making the foam amount of scraping equivalent has not caught up with the development of current technique of preparing, is primarily present a few point defect: one is the Advanced Idea having run counter to harmonious ore dressing " early catch and early receive early output "；Two be operative employee not referring in particular to operation standard；Three is that under equal conditions, operation index can not reach best。Owing to there is disadvantages described above, the economic indicator that not only can not obtain in production technology, more can not effectively reduce metal loss, both wasted resource, again cost of idleness。
Summary of the invention
Froth flotation is relatively advanced and conventional beneficiation method, and flotation is the important procedure in ore-dressing technique, and in ore-dressing technique, each production link services for flotation circuit。" harmonious ore dressing " theory: early catch and early receive early output。Valuable mineral can never be put into two-stage nitration output one section of output, can never be put into three sections of outputs in two-stage nitration output, output can be scanned roughly selecting never being put into of output, same reason, the 2nd groove output can be never put in the 1st groove output, the 3rd groove output can be never put in the 2nd groove output。Advocating today of " harmonious ore dressing " new concept in international ore-dressing technique, the present invention, by constantly groping research in production practices, sums up and obtains a kind of new flotation groove face method of adjustment, i.e. " staged adjusting method "。
The present invention is realized by following technical proposals。
A kind of flotation groove face controls method of adjustment, it is characterised in that: adopting staged flotation groove face adjusting method, each groove flotation froth amount of scraping is successively decreased to pit step by step from front groove。
Further, it is possible to selection single cavity is one-level, is called single cavity method, it is also possible to selection double flute is one-level, is called double flute method, it is also possible to selecting multiple-grooved (more than three grooves) is one-level, is called many channel process；Groove number selects single cavity method to control less, and groove number more options double flute method controls。
Further, according to practical situation, under premise few after many before following the flotation froth amount of scraping, the independent assortment of single cavity method and double flute method, carry out multiple-grooved control。
When in keeping technical process, each operation ore pulp amount is stablized and balances, the flotation device amount of scraping is scraped greatly as far as possible, but can not run and emit (race emits and refers to that flotation froth overflows flotation cell)。In same flotation region, the front groove foam amount of scraping is big, and the pit foam amount of scraping is little。
The front groove amount of scraping tunes up, and tuning up must be controlled, it is impossible to scrape ore pulp。
The pit amount of scraping is turned down, and turning down must degree of having, it is impossible to the not amount of scraping。
The ultimate principle of the present invention:
Staged flotation groove face adjusting method follow the valuable mineral content in each region in the flow direction of valuable mineral in technological process and flow process number (front many after few), take the principle in priority acccess control source to carry out single cavity or double flute or multiple-grooved operation, control to adjust the flotation device foam amount of scraping。
By ore pulp flow direction in flotation flowsheet, in same flotation region, before the content of valuable mineral of flotation device more than flotation device below, therefore, scraping (the foam amount of scraping tunes up), then in the flotation device of face, the content of valuable mineral is less therefore scrape (the foam amount of scraping is turned down) less more。Being equipped with medicament as each flotation region is previous and add point, the valuable mineral in the flotation device of foremost is the fastest with the reaction of floating agent, override, the most fully。Therefore, interregional in single flotation, few after many before adopting, what staged gradually decreased scrapes metering method。
The technique effect of the present invention: operative employee can be improved flotation groove face controlled technical ability, solve the operation knotty problem of flotation circuit。Establish the operation standard of flotation circuit in mineral processing specialty first, be the judging basis of objective evaluation flotation groove face control adjustment。The present invention is not limited only to the flotation groove face adjustment of slag ore dressing, it is also possible to use in the flotation circuit being generalized to all Mineral Processing Industries。
Accompanying drawing explanation

Detailed description of the invention
A kind of flotation groove face controls method of adjustment, it is characterised in that: adopting staged flotation groove face adjusting method, each groove flotation froth amount of scraping is successively decreased to pit step by step from front groove。Can select single cavity is one-level, is called single cavity method, it is also possible to selection double flute is one-level, is called double flute method, it is also possible to selecting multiple-grooved (more than three grooves) is one-level, is called many channel process；Groove number selects single cavity method to control less, and groove number more options double flute method controls。
, ultimate principle
Staged flotation groove face adjusting method follow the valuable mineral content in each region in the flow direction of valuable mineral in technological process and flow process number (front many after few), take the principle in priority acccess control source to carry out single cavity or double flute or multiple-grooved operation, control to adjust the flotation device foam amount of scraping。
By ore pulp flow direction in flotation flowsheet, in same flotation region, before the content of valuable mineral of flotation device more than flotation device below, therefore, scraping (the foam amount of scraping tunes up), then in the flotation device of face, the content of valuable mineral is less therefore scrape (the foam amount of scraping is turned down) less more。Being equipped with medicament as each flotation region is previous and add point, the valuable mineral in the flotation device of foremost is with floating agentReactionIt is the fastest, override, the most fully。Therefore, interregional in single flotation, few after many before adopting, what staged gradually decreased scrapes metering method。
2, method of adjustment contrast (as shown in Figure 1)
Staged flotation groove face adjusting method follow the valuable mineral content in each region in the flow direction of valuable mineral in technological process and flow process number (front many after few) take the principle in priority acccess control source to carry out single cavity or double flute or multiple-grooved operation, control to adjust the foam amount of scraping。This method can obtain best production target。
(2) the adjustment of the flotation groove face of traditional method is that the flotation groove face in same flotation region must control in same level。The foam amount of scraping making each flotation groove face in same flotation region is equal to。This method does not meet harmonious ore dressing theory, can only obtain general production target。
(3) wrong method is in same flotation region, and the pit amount of scraping is bigger than the front groove amount of scraping, and has run counter to the principle that Sources controlling is preferential。This does not make control adjust, and is referred to as to let alone adjustment。This method does not meet harmonious ore dressing theory, and production target is worst。
In figure, the shading table of " black " part shows the content of valuable mineral。
Valuable mineral in ★ dense expression region is many。
Valuable mineral in ★ light expression region is few。
Staged flotation groove face adjusting method has reached early to catch the science flotation purpose early receiving early output, meets the Advanced Idea of " the harmonious ore dressing " advocated in international ore-dressing technique。
3, method of adjustment selects
Be adopt staged method 1(single cavity) or staged method 2(double flute), can according to the flotation trough number in flow process or flotation region number select。
★ groove number selects staged method 1 less, carries out single cavity control。
★ groove number more options staged method 2, carries out double flute control。
(2) the practical situation according to groove face is determined。
★ single cavity is easily controlled, then select staged method 1。
★ single cavity difficulty controls then to realize double flute control, selects staged method 2。
(3), under pre-large post-small premise, it may be achieved the independent assortment of staged method 1 and staged method 2, carry out multiple-grooved control。
4, groove face Adjustment principle
Total Adjustment principle is: when in keeping technical process, each operation ore pulp amount is stablized and balances, the flotation device amount of scraping is scraped greatly as far as possible, but can not run and emit。In same flotation region, the front groove foam amount of scraping is big, and the pit foam amount of scraping is little。
Before ★, the groove amount of scraping tunes up, and tuning up must be controlled, it is impossible to scrape ore pulp。
The ★ pit amount of scraping is turned down, and turning down must degree of having, it is impossible to the not amount of scraping。
The advantage of staged adjusting method
Staged adjusting method overcomes the shortcoming and defect existed in traditional operation technology, applied range, has promotional value widely。The flotation circuit of all Mineral Processing Industries can be applied to, minimizing metal loss can be played, improve the effect of floatation indicators, floating operation body of tool can be instructed to operate, be the inspection floating operation work standard to groove face control adjustment capability。
Staged adjusting method has possessed originality, advance, application, simplification, safety, it is adaptable to floating separation and environment protection sewage process。It has broken the foam surface of traditional same flotation region flotation device must in the equal principle of same level or the same flotation region flotation device foam amount of scraping, it it is an original method leading over the same industry, valuable mineral can be better controled over and be flowed into down one flotation circuit, advantageously reduce mine tailing cupric, control metal loss, accomplish early reaction early output, met harmonious ore dressing new concept, reached the purpose of science flotation。
Application example
1, in the flotation device of legacy system < 1 cubic metre, the airduct of first trough floatation machine in each flotation region easily blocks, roughly selected 1st district at that time and chats flotation 1 district blocked often, stopping every time and will conscientiously confirm stopping state, this is that the tradition adjusting method requirement amount of scraping is equal to and causes。Because there being agitator tank before roughly selecting, having chemical feeding points in groove, the mineralized froth formed in advance flows into the 1st groove, and not air blast foam is also very abundant, and for pursuing the equivalent amount of scraping, the air quantity of the 1st groove is turned down by operative employee, so, the flotation device airduct of the 1st groove is easy to blocking。
In tradition adjusting method, collecting agent is caught the valuable mineral compacting caught and is not allowed output or delayed output, and this turns out traditional method of adjustment not science, has run counter to harmonious principle, and this method of adjustment does not catch up with the development of ore dressing operating technology！
2, selecting one section to be made up of 40 cubic metres of flotation devices of two grooves at new slag, the 1st groove mineralized froth enriches, and foam can be emerged to case upper end, ore deposit, can suppress air quantity, often cause foam tacky when pursuing the equivalent amount of scraping, and the amount of scraping is not smooth, easily causes " extremely bubble " phenomenon。
After adopting staged adjusting method, one section of flotation is to the no longer bubbling of case upper end, ore deposit, and bubble mobility is good, no longer tacky, and " extremely bubble " phenomenon eliminates。
Staged adjusting method controls the development immediately following technique of preparing, proper production reality, has accomplished early reaction early output, has met harmony ore dressing new concept, has been conducive to improving concentrate grade, reduces mine tailing cupric, effectively reduce metal loss。
3, from since 2005, being operated by work to the grasp of staged adjusting method and utilization, the mine tailing cupric index of new slag choosing has breakthrough every year。
