Description
Technical field
The present invention relates to a kind of beneficiation method of low-grade difficult scheelite, using the present invention can from containing calcite,
Tungsten concentrate is obtained in the low-grade difficult scheelite stone of fluorite.
Background technology
Tungsten resource is the Dominant Mineral Resources in China, and reserves account for the 68% of world's tungsten resource total amount.However, as its people pass through
The fast development of Ji, the consumption of China's tungsten resource are serious.In fast industrialization process for many years, the excessive exploitation of this resource makes
The tractable tungsten ore in China (wolframite for being easy to gravity treatment enrichment) is almost depleted.It is formed with the excessively exploitation of disposable resource fresh
Bright comparison is that China is very low for the development and utilization level of the difficult tungsten resource (low-grade scheelite) of rich reserves.Low product
Position scheelite resource reserves accounts for the 70% of China's tungsten resource gross reserves.By ore type, scheelite can be divided into scheelite-stone
English (or silicate mineral) type, scheelite-two major class of calcite-fluorite (or barite) type, when gangue is with quartz or silicate
Mineral for it is main when scheelite stone easily sort, and scheelite-calcite-fluorite (barite) type ore then floating due to mineral
The more difficult sorting of similar temperament.
The flotation of scheelite can be generally divided into two stages, i.e. roughing section and selected section, and roughing section is to improve concentration ratio
As the main purpose, selected section to upgrade as the main purpose.In flotation practice, white tungsten roughing technique is generally with pH regulators
Species name, it is common have sodium carbonate method, lime method and lime+sodium carbonate method.The method for concentrating of white tungsten includes room temperature essence
Method and heating concentration method are selected, it is relatively low that normal temperature method is applied to sorting index during calcite type scheelite；Floatation is heated to ore
Adaptability is stronger, and sorting index is stablized, but energy consumption is big, of high cost, complicated for operation.Therefore, developing has calcic gangue mineral
More highly selective inhibitor, realization scheelite is efficiently separated with calcic gangue, to realizing low-grade difficult scheelite
It efficiently utilizes and is of great significance.
The content of the invention
It is an object of the invention to provide a kind of beneficiation method of low-grade difficult scheelite, solving scheelite can not be with
The technique of preparing problem of efficient, the inexpensive FLOTATION SEPARATION of calcite, fluorite.
The present invention comprises the following steps：
A, ore preparation and ore grinding, obtain ore grinding ore pulp, and mog accounts for Zong Kuang for the ore of -0.074mm granularity level
Stone mass percent is 50%-55%；
B, table concentration and regrind, the ore grinding ore pulp that step A is obtained is classified with 0.037mm ,+0.037mm grades carry out
Table concentration obtains tungsten gravity concentrate；Flotation is carried out after table concentration tailing is regrinded and after the mixing of -0.037mm grades, then it is levigate
It is 70%-80% that the ore spent for -0.074mm granularity level, which accounts for total ore quality percentage,；
C, floatation desulphurization adds in collecting agent butyl xanthate and foaming agent in the ore pulp for needing to carry out flotation obtained in step B
No. two oil flotations remove sulphide ore, and collecting agent butyl xanthate dosage used is 40-80g/t, and the oily dosage of foaming agent 2 is 10-20g/
t；
D, roughing, add in the ore pulp after step C flotation removing sulphide ores regulator sodium carbonate, inhibitor YFW-12 and
Collecting agent BF-01 carries out roughing operation, obtains rougher concentration and rougher tailings；Inhibitor YFW-12 is pressed by citric acid and waterglass
Mass ratio 1：2-4 mixing compositions；Collecting agent BF-01 is by enuatrol, benzyl hydroximic acid, ethyl alcohol in mass ratio 3：2：1 mixing composition；
Sodium carbonate amount used in roughing is 1000-1500g/t, and inhibitor YFW-12 dosages are 2000-3000g/t, and collecting agent BF-01 is used
It measures as 120-180g/t；
E, scan, inhibitor YFW-12 and collecting agent BF-01 is added in the rougher tailings obtained in step D and carries out secondary sweep
Choosing, obtains true tailings, scans middling recurrence for the first time to roughing, scans middling recurrence for the second time to scanning for the first time, and first
For secondary inhibitor YFW-12 dosages of scanning for 1000-1500g/t, collecting agent BF-01 dosages are 60-90g/t；It scans and only adds for the second time
Collecting agent BF-01, dosage 60-90g/t；
F, it is selected, inhibitor YFW-12 is added in the rougher concentration obtained in step D and carries out triple cleaning, obtains tungsten flotation
Concentrate, first time selected middling recurrence to roughing, second of selected middling recurrence is selected to first time, and the selected chats of third time returns
It returns to selected for the second time；Selected inhibitor YFW-12 dosages are 500-700g/t, second of selected inhibitor YFW-12 for the first time
Dosage is 200-300g/t, and the selected inhibitor YFW-12 dosages of third time are 200-300g/t.
The present invention develops new inhibitor YFW-12, which can reduce collecting agent in calcite, fluorite surface
Adsorbance, without influence collecting agent scheelite surface absorption, to calcite, fluorite have selective depression ability,
Medicament is nontoxic, at low cost simultaneously.New collector BF-01 is developed, the collecting agent collecting ability is strong, to good environmental adaptability.
The efficient utilization of the scheelite containing calcite, fluorite, remarkable in economical benefits can be realized using two kinds of medicaments.
