The invention discloses the combined modifiers and its application method of a kind of flotation magnesium skarn type copper sulfide ore, belong to Mineral Processing Engineering technical field.The combined modifier uses caustic soda, three kinds of vulcanized sodium, waterglass pharmaceutical agent combinations, and the proportion of three kinds of medicaments is caustic soda: vulcanized sodium: waterglass=20~40:0.5~2:1~5.Compared with conventional copper-sulphide ores regulator lime, three kinds of medicament synergistic effects, are more advantageous to inhibitor performance and collecting agent performance plays, and increase substantially the mineral processing index of copper, there is market application value.
Description
Technical field
The present invention relates to the regulators and its application of a kind of flotation magnesium skarn type copper sulfide ore, belong to mineral processing skill
Art field.
Background technique
Currently, common copper-sulphide ores flotation pH regulator is mainly lime, such as Dexing copper mine, Dongguashan Copper Mine.Stone
Ash has source wide, the relatively cheap feature of price, and during vulcanization copper ore floatation, the property of can choose inhibits yellow iron
Mine has obtained extensive industrial application.
Often contain a large amount of phlogopite, talcum, chlorite, snake in copper sulfide ore due to resulting from magnesium skarn
The clay minerals such as stone, kaolinite, when lime, which is applied to flotation, results from the copper sulfide ore of magnesium skarn, there are some to ask
Topic: firstly, lime itself is a kind of common flocculating agent, large quantities of lime is added in ore pulp, clay pit in ore pulp can be promoted
Composition granule and copper-sulphide ores composition granule heterocoagulation, are unfavorable for the dispersion and FLOTATION SEPARATION of mineral grain；Secondly, mine is added in lime
A large amount of calcium ion and calcium hydroxy compounds are brought in slurry, these containing Calcium compounds can clay mineral and sulfide mineral surface without
Selective absorption causes inhibitor to be difficult to select to inhibit clay mineral, and FLOTATION SEPARATION is difficult；Furthermore the use of lime will lead to
Pipeline and empty fouling, influence the normal operation of floatation equipment (such as flotation column) and pipeline.Therefore, using novel regulator pair
The flotation of magnesium skarn type copper sulfide ore has great importance.
The present invention uses the mixture of caustic soda, vulcanized sodium and waterglass as flotation magnesium skarn type copper sulfide ore for the first time
Floatation regulator achieves extraordinary flotation effect.Its mechanism of action are as follows: strengthen dispersion ore pulp CLAY MINERALS AND THEIR SIGNIFICANCE and copper sulfide
Mineral grain hinders the foam entrainment of hydrophily gangue mineral；The adverse effect of unavoidable ion in ore pulp is eliminated, inhibitor is strengthened
Selective inhibitory.
Summary of the invention
In order to overcome the shortcomings of regulator in existing magnesium skarn type copper sulfide ore flotation, the first purpose of this invention
It is to provide a kind of new combined modifier for flotation magnesium skarn type copper sulfide ore, significant effect, with vulcanization
Copper Ores regulator is compared, and combined modifier is conducive to strengthen the dispersion of clay mineral and copper-sulphide ores composition granule, promotes to inhibit
The selective inhibitory of agent, increases substantially mineral processing index.
The purpose of the present invention is what is be accomplished by the following way:
A kind of combined modifier of flotation magnesium skarn type copper sulfide ore: being by three kinds of caustic soda, vulcanized sodium, waterglass medicines
Agent combination；The quality proportioning of the combined modifier is caustic soda: vulcanized sodium: waterglass=20~40:0.5~2:1~5.
Further, the quality proportioning of the combined modifier is caustic soda: vulcanized sodium: waterglass=20~30:0.5
~2:1~5.
Further, the quality proportioning of the combined modifier is preferably caustic soda: vulcanized sodium: waterglass=20~
25:0.5~2:1~5.
A second object of the present invention is to provide the applications of the combined modifier of above-mentioned magnesium skarn type copper sulfide ore.This
Invention will be used for flotation magnesium skarn type copper-sulphide ores by the regulator of three kinds of caustic soda, vulcanized sodium, waterglass pharmaceutical agent combinations for the first time
Stone.Its significant effect promotes the selective inhibitory of inhibitor, increases substantially mineral processing index.
As regulator when specific application is flotation magnesium skarn type copper sulfide ore.
Further, the combined modifier with adjust slurry pH be 10.0~11.5 be terminal determine be added
Amount；It is preferred that adjustment slurry pH range is 10.5~11.0.
The present invention by the quality proportioning of combined modifier preferably with the preferred amount ranges of combined modifier arrange in pairs or groups, can more into
One step promotes the effect of regulator, improves mineral processing index to the greatest extent.
The combined modifier of flotation magnesium skarn type copper sulfide ore of the present invention in specific application, by caustic soda,
Ore grinding in grinding machine is proportionally added in vulcanized sodium and waterglass simultaneously with ore, add collecting agent, inhibitor and foaming agent into
Row flotation.
In specific application, what is used catches the combined modifier of flotation magnesium skarn type copper sulfide ore of the present invention
Receiving agent includes: one of butyl xanthate, butyl ammonium aerofloat, Z-200, penta xanthate, sulphur ammonium esters collecting agent, Thiourea collecting agent or several
Kind；Inhibitor includes such as guar gum, sodium carboxymethylcellulose, modified cellulose class inhibitor, sodium humate, sodium lignin sulfonate
One or more of；Foaming agent includes one or more of 2# oil, MIBC, BK210.The collecting agent, rises inhibitor
The usage amount of infusion is according to conventional amount used.
The present invention has the advantage that and good effect: using the group cooperation of caustic soda, three kinds of vulcanized sodium, waterglass medicaments for the first time
Flotation is carried out to magnesium skarn type copper sulfide ore for regulator, can effectively disperse clay mineral and copper-sulphide ores composition granule,
The foam of hydrophily gangue mineral is hindered to carry phenomenon, such as phlogopite, serpentine, kaolinite secretly；Eliminate unavoidable ion in ore pulp
Adverse effect, strengthen the selective inhibitory of inhibitor, the easily floating gangue mineral of selective depression, such as talcum, chlorite
Deng；To be conducive to the FLOTATION SEPARATION of mineral, the grade and the rate of recovery of copper concentrate are improved, mineral processing index is increased substantially.
