Description
Technical field
Regulator and its application the present invention relates to a kind of flotation magnesium skarn type copper sulfide ore, belong to mineral processing skill
Art field.
Background technology
At present, conventional copper-sulphide ores flotation pH regulators are mainly lime, such as Dexing copper mine, Dongguashan Copper Mine.Stone
Ash has the characteristics of source is wide, and price is relatively cheap, during vulcanization copper ore floatation, can be with Selective depression Huang iron
Ore deposit, has obtained extensive commercial Application.
Due to often containing substantial amounts of phlogopite, talcum, chlorite, snake in the copper sulfide ore for resulting from magnesium skarn
, when lime is applied to flotation results from the copper sulfide ore of magnesium skarn, there is asking for some in the clay minerals such as stone, kaolinite
Topic：First, lime is in itself a kind of conventional flocculating agent, and large quantities of lime is added in ore pulp, can promote clay pit in ore pulp
Composition granule and copper-sulphide ores composition granule heterocoagulation, are unfavorable for dispersion and the FLOTATION SEPARATION of mineral grain；Secondly, lime adds ore deposit
Substantial amounts 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 selection and suppresses clay mineral, and FLOTATION SEPARATION is difficult；Furthermore, the use of lime can cause
Pipeline and empty fouling, influence floatation equipment (such as flotation column) and the normal operation of pipeline.Therefore, using new 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 first
Floatation regulator, achieves extraordinary flotation effect.Its mechanism of action is：Reinforcing 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, strengthens inhibitor
Selective inhibitory.
The content of the invention
In order to overcome the shortcomings of regulator, first purpose of the invention in existing magnesium skarn type copper sulfide ore flotation
It is to provide a kind of new combined modifier for flotation magnesium skarn type copper sulfide ore, its effect is significant, with vulcanization
Copper Ores regulator is compared, and combined modifier is conducive to strengthening the dispersion of clay mineral and copper-sulphide ores composition granule, promotes to suppress
The selective inhibitory of agent, increases substantially mineral processing index.
The purpose of the present invention is achieved in the following ways：
A kind of combined modifier of flotation magnesium skarn type copper sulfide ore：It is by caustic soda, vulcanized sodium, three kinds of medicines of waterglass
Agent is combined；The quality proportioning of described combined modifier is caustic soda：Vulcanized sodium：Waterglass=20~40:0.5~2:1~5.
Further, the quality proportioning of described combined modifier is, caustic soda：Vulcanized sodium：Waterglass=20~30:0.5
~2:1~5.
Further, the quality proportioning of described combined modifier is preferably, caustic soda：Vulcanized sodium：Waterglass=20~
25:0.5~2:1~5.
Second object of the present invention is to provide the application 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 caustic soda, vulcanized sodium, three kinds of regulators of pharmaceutical agent combinations of waterglass first
Stone.Its effect is significant, promotes the selective inhibitory of inhibitor, increases substantially mineral processing index.
As regulator when specifically application is flotation magnesium skarn type copper sulfide ore.
Further, described combined modifier with adjust slurry pH be 10.0~11.5 for terminal determine add
Amount；It is preferred that adjustment slurry pH scope is 10.5~11.0.
The present invention preferably arranges in pairs or groups the quality proportioning of combined modifier with the preferred amount ranges of combined modifier, can more enter
One step lifts the effect of regulator, farthest improves mineral processing index.
The combined modifier of flotation magnesium skarn type copper sulfide ore of the present invention in concrete application, by caustic soda,
Vulcanized sodium and waterglass proportionally add ore grinding in grinding machine simultaneously with ore, add collecting agent, inhibitor and foaming agent and enter
Row flotation.
In concrete application, what is used catches the combined modifier of flotation magnesium skarn type copper sulfide ore of the present invention
Receiving agent includes：One kind or several in butyl xanthate, butyl ammonium aerofloat, Z-200, penta xanthate, sulphur ammonium esters collecting agent, Thiourea collecting agent
Kind；Inhibitor includes such as guar gum, sodium carboxymethylcellulose, modified cellulose class inhibitor, sodium humate, sodium lignin sulfonate
In one or more；Foaming agent includes one or more in 2# oil, MIBC, BK210.Described collecting agent, inhibitor, rise
The usage amount of infusion is according to conventional amount used.
The present invention has the advantage that and good effect：Made using the combination of caustic soda, vulcanized sodium, three kinds of medicaments of waterglass first
For regulator carries out flotation to magnesium skarn type copper sulfide ore, can effectively dispersed clay mineral and copper-sulphide ores composition granule,
Hinder the foam entrainment phenomenon of hydrophily gangue mineral, such as phlogopite, serpentine, kaolinite；Eliminate unavoidable ion in ore pulp
Adverse effect, strengthen the selective inhibitory of inhibitor, such as easily floating gangue mineral of Selective depression, talcum, chlorite
Deng；So as to be conducive to the FLOTATION SEPARATION of mineral, the grade and the rate of recovery of copper concentrate are improved, increase substantially mineral processing index.
