Description
Technical field
The invention belongs to technical field of beneficiation, in particular to the colour sorting-of a kind of mica containing rubidium-feldspar ore is flotation combined
Beneficiation method.
Background technique
Rubidium is a kind of yttrium, since it is with special photoelectric properties, is referred to as the gold of " long eyes "
Belong to.Which are mainly applied to the fields such as new and high technology exploitation and electronic device, special glass.It is independent not yet to find that there are rubidiums at present
Mineral, and it is often present in mica in the form of isomorphous.Mica in ore often with adapt to the close symbiosis such as feldspar.
Because of the easy argillization of mica and feldspar, quartzy harder characteristic, ore grinding is meticulous to will lead to a large amount of mica minerals losses.It is therefore desirable to
It is proposed that effective scheme solves the above problems.Through research investigation discovery, the color of mineral containing rubidium and gangue mineral (quartz) have larger area
Not, gangue mineral quartz is often the light color such as white, and the dark system such as black can be presented in mica containing rubidium etc., therefore according to colors of mineral
Composition can be pre-processed, and select valuable rock part in advance, reduce gangue treating capacity, improve operating efficiency.
Summary of the invention
To overcome the defects of above-mentioned background technique, the present invention is according to the colour-difference of mica containing rubidium and feldspar, quartz mineral
It is different, a kind of beneficiation method of environment-friendly high-efficiency is provided.
To achieve the goals above, technical solution of the present invention is specific as follows:
A kind of flotation combined beneficiation method of colour sorting-of mica containing rubidium-feldspar ore, includes the following steps:
Step 1, it is crushed: the ore of extraction being spared to and is crushed to 0-20mm or so into jaw crusher, wherein being greater than
20mm part pass through sieve classification be back to crushing circuit formed it is closed circuit, less than 20mm part enter colour sorter be subsequent point
Choosing is prepared.
Step 2, colour sorting: step 1 products obtained therefrom is sent into colour sorter, sorting machine makes according to mineral color difference
Two different colors of ore is sub-elected with air cannon.The sorting machine is mainly by feeding system, Systems for optical inspection, signal processing
System and separation execution system composition.Mineral are evenly supplied to optical detecting parts by belt feeder, are sorted by computer settings
Color gamut；When mineral region after testing, according to range is preset, dark mine will be hit by air cannon and sort out
Come, light-colored part is directly entered in next splicing storehouse, realizes two parts separation.
Step 3, it is crushed ore grinding: by useful part in the product of step 2 (dark mine) even feeding into jaw crusher,
Broken product carries out sieve classification, wherein the part greater than 2mm is back to and continues to be crushed in crusher, particle size after cracking is made to exist
2mm or less.
Step 4, step 3 gained fragment is fed into ball mill, is milled to -200 mesh contents 70% or so.Production after ore grinding
Since wherein mica content is relatively high in product, it is easy to produce argillization phenomenon；After hydrocyclone desliming, into roughing process
Operation.
Step 5, use sulfuric acid to be inhibitor and amine as collecting agent as pH regulator, waterglass to sequentially add
In flotation cell, dosage distinguishes pH regulator (sulfuric acid) 300-500g/t, inhibitor (waterglass) 50-2000g/ with raw ore meter
T, amine collector (20-800g/t)；After roughing twice, concentrate enters subsequent fine and is elected to be industry, and tailing is scanned, and scans
Appropriate collecting agent is added in part, and dosage halves, and scavenger concentrate returns to roughing operation, and tailing is as true tailings.
Step 6, a small amount of sulfuric acid acidification adjustment pH is added in rougher concentration before carrying out selected operation, and cleaning technological flowasheet is divided into
Two sections, selected gained concentrate enters next section of cleaning technological flowasheet for the first time, and tailing is back to roughing.
Step 7, second of selected operation mainly carries out step 6 product selected in the case where being added without any medicament
Processing, gained concentrate product is as final concentrate.
Step 8, it scans, tailing addition collecting agent is scanned, closed circuit flow is formed.
Beneficial effects of the present invention, the present invention provide one kind according to the color difference of mica containing rubidium and feldspar, quartz mineral
The beneficiation method of environment-friendly high-efficiency can be pre-processed according to colors of mineral composition, be divided using physical method mineral
From processing, valuable rock part is selected in advance, promotes raw ore Beneficiation Feed Grade, reduces gangue treating capacity, improves operating efficiency.
Detailed description of the invention
Fig. 1 is the process flow chart of the method for the present invention.
Specific embodiment
The present invention is described in detail with reference to the accompanying drawing, by taking the Mica Mine containing rubidium oxide 0.91% as an example, using such as
Process flow of the invention shown in Fig. 1.
The mineral that the present embodiment uses are fairly simple, the mineral main component be mica, feldspar, quartz and it is a small amount of other
Mineral.Through analyzing, Rb is averagely contained in the mineral2O 0.91%, wherein melanocratic mineral is higher by about 1.5% or so containing rubidium.
After optimizing engineer testing, on the basis of Best experimental condition, closed-circuit test is carried out according to Fig. 1 technique,
Include the following steps:
Step 1, be crushed: ore reduction being less than 20mm or so using jaw crusher, the particle greater than 20mm return after
It is continuous broken, 2, which are entered step, less than the part 2mm is further processed.
Step 2, colour sorting: step 1 products obtained therefrom is uniformly sent into colour sorter by belt-conveying, is adjusted
COMPUTER PARAMETER, control detection system select wherein melanocratic mineral, make it according to different minerals color difference, will using air cannon
Melanocratic mineral therefrom separates, and the melanocratic mineral and leucocratic mineral after choosing respectively enter in two splicing storehouses.
Step 3, melanocratic mineral obtained in step 2 is continued to be crushed using jaw crusher, and carries out sieve classification
Processing, wherein the part return greater than 2mm is crushed to process and continues to be crushed to 2mm or less；Part less than 2mm adds water to goal
Ball milling operation is carried out in grinding machine.
Step 4, ore grinding, by -2mm product ball mill ore grinding obtained by step 3, it is desirable that product -0.074mm content is
70%, the product after ore grinding enters hydrocyclone and carries out desliming process.
Step 5, flotation: the product after desliming successively carries out roughing twice, once purging selection and selected twice；In terms of raw ore,
460g/t pH regulator, 1600g/t inhibitor, 400g/t and 100g/t amine collector are added when roughing I；Roughing II is added
200g/t and 50g/t amine collector；180g/t inhibitor is added in selected I；It scans I and the collecting of 100g/t and 25g/t amine is added
Agent；
The results are shown in Table 1 for the present embodiment closed-circuit test
1 closed-circuit test result of table
Technical solution of the present invention is described in detail in above-described embodiment.It is apparent that the present invention is not limited being retouched
