Description
Technical field
The present invention relates to tailings glass field, be specifically related to a kind of ultra-fine grade mine tailing method for separating.
Background technology
Submicron-sized particulate mine tailing, generally include that disseminated grain size is tiny, useful constituent be difficult to even cannot the material of monomer dissociation,
Or material is by over grind during monomer dissociation, part useful constituent, presented in submicron-sized particulate, uses routine
Isolation technics is difficult to its resource reclaim.On ordinary meaning, the disseminated grain size that submicron-sized particulate material refers generally to useful constituent is remote
Material much smaller than 75 μm.
Along with the progress of science and technology, the such as magnetic separation, flotation of the conventional means of resources processing, gravity treatment all start to fine
Sorting infiltration, and make some progress.As a example by flotation, traditional view think fine mineral can not flotation, and
A lot of operator also pay special attention to the overground of material to be avoided or " argillization ".Submicron-sized particulate material commonly uses separation method for carrying
Flotation body, this technique is to utilize other easily floating more rough grain to do carrier, optionally adheres to micro-, particulate target minreal therewith
The method of emersion together, and spontaneous carrier flotation technique is the floatation process utilizing same mineral to make carrier.
Summary of the invention
In order to solve above technical problem, the invention provides the method for separating of a kind of ultra-fine grain, comprise the following steps:
Ultra-fine grade mine tailing containing concentrate granule and gangue mineral adds mixing drum together with neutral oil；
Enter cylinder after sufficiently mixing, concentrate granule float together with neutral oil formed overhead stream flow into add hot charging
Putting, gangue mineral and water are formed after underflow adds flocculant and enter Paste thickener；
The overhead stream comprising concentrate granule and neutral oil is clean by regenerating unit through the dried neutral oil of heating devices heat
Change, return to described mixing drum and recycle, collect remaining concentrate granular powder, neutral oil and concentrate granule and pass through heating,
Both can reclaim neutral oil, mineral can be dried again；
After the underflow comprising gangue mineral and water enters Paste thickener, through flocculant effect, it is achieved solid-liquid separation, overflow
Primary water returns, and recycles, and underflow is flowed out, and underflow stone-like pulse tailings concentration, up to 70%～80%, is applied directly to building materials deep
In processing.
The method for separating of ultra-fine grain provided by the present invention, wherein cylinder preferred multiple stage separation cylinder, can be by one-level
Cylinder, two poles separate and three grades separate composition, two, three grades of buckets be mainly further Separation of Neutral oil float the water brought out and
Gangue mineral, ultra-fine grade mine tailing and the blended cylinder of neutral oil enter flash trapping stage cylinder, the generation of flash trapping stage cylinder after being sufficiently mixed
Overhead stream flow into the second-order separation cylinder, three grades of cylinders of inflow that the second-order separation cylinder produces, the overhead stream that three grades of cylinders produce flows into
Heater, the underflow of flash trapping stage cylinder, the second-order separation cylinder and three grades of cylinders adds flocculant and enters Paste thickener.
The method for separating of ultra-fine grain provided by the present invention, uses the method for oil aggregation to be enriched with ultra-fine grade mine tailing, oil
Reunion is to add collecting agent in ore pulp to make ultra-fine grade mineral hydrophobic, then adds neutral oil, and neutral oil is at hydrophobic granule table
Face is sprawled, and promotes subparticle to be gathered in oil phase formation group, thus increases the apparent particle diameter of fine-grained particles.Pass through profit again
Separate, reach the purpose of sorting, finally reclaim neutral oil, recycle after purification.
Oil aggregation neutral oil used in invention is hydro carbons, has and selects and the character of overseas Chinese federation.According to the difference of mineral, choosing
Selecting different medicaments, the activity order of hydro carbons is: aromatic hydrocarbons ＞ alkene ＞ isoparaffin ＞ cycloalkane ＞ n-alkane；Polycyclic aromatic hydrocarbon
＞ mononuclear aromatics；The non-alkylaromatic hydrocarbon of many alkylaromatic hydrocarbons ＞, selectivity is contrary.It is simultaneously introduced the collecting agent such as kerosene, diesel oil.
The method for separating of ultra-fine grain provided by the present invention sorts for ultra-fine grade mine tailing, has response rate height, divides
Select the features such as efficiency high cost is low.Solve conventional flotation technology and cannot sort a difficult problem for ultra-fine grade mine tailing.And technique stream
Journey is simple, and apparatus processing is convenient, workable.Conventional oil reunion separation method is flotation or screening, and the present invention is without flotation
Or screening, use the form of heating evaporation to reclaim neutral oil, there is the highest response rate, concentrate is dried simultaneously.
Accompanying drawing explanation
Fig. 1 is the method for separating schematic flow sheet of ultra-fine grain provided by the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
The method for separating of ultra-fine grain as described in Figure 1, comprises the following steps:
Ultra-fine grade mine tailing containing concentrate granule and gangue mineral adds mixing drum 1 together with neutral oil；
Entering cylinder 2 after sufficiently mixing, concentrate granule the formed overhead stream that floats together with neutral oil flows into two fraction
From cylinder 3, three grades of cylinders 4 of inflow that the second-order separation cylinder 3 produces, the overhead stream that three grades of cylinders 4 produce flows into heater 5, and one
The underflow of level cylinder 2, the second-order separation cylinder 3 and three grades of cylinders 4 adds flocculant and enters Paste thickener 7；
The overhead stream comprising concentrate granule and neutral oil neutral oil after heater 5 heat drying passes through regenerating unit 6
Purify, return to described mixing drum 1 and recycle, collect remaining concentrate granular powder；
After the underflow comprising gangue mineral and water enters Paste thickener 7, through flocculant effect, it is achieved solid-liquid separation, overflow
Stream primary water returns, and recycles, and underflow is flowed out, and underflow stone-like pulse tailings concentration, up to 70%～80%, is applied directly to building materials
In deep processing.
The method for separating of this ultra-fine grain sorts for ultra-fine grade mine tailing, has response rate height, efficiency of separation high cost
The feature such as low.Solve conventional flotation technology and cannot sort a difficult problem for ultra-fine grade mine tailing.And technological process is simple, and equipment adds
Work is convenient, workable.Conventional oil reunion separation method is flotation or screening, and the present invention adds without flotation or screening, employing
The form of thermal evaporation reclaims neutral oil, has the highest response rate, is dried concentrate simultaneously.
