Abstract
A novel combined flotation regulator of mineral phosphate containing siliceous gangue relates to a flotation regulator applicable to mineral phosphate that has a large silt content and mainly containssiliceous gangue and belongs to the technical field of mineral processing engineering. The regulator adopts another three drugs combined for use in normal sodium carbonate regulator, and the mixtureratio of sodium carbonate: table salt:caustic soda:water glass in the combined regulator is 2-2.5:0.2-0.5:0.8-1.2:1-1.5. The three drugs are synergistic to obtain obvious and better effect than sodiumcarbonate singly used and be more beneficial to the development of catching performance of catching agent oxidized paraffin wax soap. In use, the consumption amount of the combined regulator is rather less than that of the sodium carbonate singly used, and the combined regulator is beneficial to settlement of concentrate, wide in the source of raw materials, moderate in price and has market promotion value.
Description
Affiliated technical field
The present invention relates to a kind of flotation, to contain siliceous gangue be that main phosphorus ore thing is adjusted the efficient adjustment agent that agent, especially flotation contain the many collophanes of mud.
Background technology
At present, it is sodium carbonate, sulfuric acid etc. that collophane commonly used is adjusted agent, and these are adjusted agent and all have some problems in actual applications.As when adopting sodium carbonate for the adjustment agent, the collophane consumption soda ash amount that majority contains siliceous gangue is about 5～8kg/t, even higher, and the foam viscosity is big, is not easy froth breaking, concentrate sedimentation difficulty; And adopt the adjustment agent of sulfuric acid as carbonate containing gangue collophane, and not only consumption is big, the cost height, and equipment anticorrosion is difficult to effective solution with the scale problems in wastewater treatment and the flotation cell.
Summary of the invention
In order to overcome the deficiency of adjusting agent in the existing phosphorus ore thing flotation, the invention provides the combined modifier that a kind of flotation contains siliceous gangue phosphorus ore thing, its effect is significantly adjusted the agent agent with conventional collophane and is compared, have that consumption is few, foam is salubrious, be beneficial to the concentrate sedimentation, tailing water does not have greasy dirt, wide, the moderate advantage of raw material sources.
Solving the technical scheme that technical problem of the present invention adopts is: adjust in the agent at conventional sodium carbonate and be used in combination other three kinds of medicaments, a kind of is inorganic salts salt; A kind of is caustic soda; Another kind is a waterglass.The proportioning of combined modifier is: sodium carbonate: salt: caustic soda: waterglass=2～2.5: 0.2～0.5: 0.8～1.2: 1～1.5, four kinds of medicament synergies are better than independent use sodium carbonate effect.Use this combined modifier, the consumption of adjusting agent can reduce significantly, because the soda ash price is relatively more expensive in all medicaments of flotation phosphate mineral, is very favorable to reducing the flotation cost like this.
The using method of collecting agent of the present invention is, after adding soda ash, adds salt earlier, adds sodium carbonate, caustic soda, waterglass then successively, and mixing time is 3 minutes.The interpolation of soda ash once in ore mill, once mixes being added in the flotation cell all at twice with oxidized paraffin wax soap.
Advantage that the present invention has and good effect:
It is main phosphorus ore thing that flotation is contained siliceous gangue, can reduce the medicine consumption of conventional sodium carbonate significantly, in the cost-effective while, strengthens the collecting performance of collecting agent, makes ore pulp salubrious, is beneficial to sedimentation.Be used in combination to have than independent use sodium carbonate and size mixing preferably and inhibitory action, the combined modifier raw material sources are wide, moderate, and market popularization value is arranged.Use CS combined modifier consumption of the present invention to be about 4kg/t, concentrate grade can be brought up to more than 30%, and the rate of recovery can reach more than 40%, and the concentrate effect of settling is relatively good.
Description of drawings
Fig. 1 is combined modifier of the present invention application technology flow chart in flotation.
Fig. 2 is applied in the flotation process figure of other local rock phosphate in powder for combined modifier of the present invention.
The specific embodiment
Embodiment 1:
Contain the apatite mine tailing after to Longling iron ore magnetic separation and handle, this sample ore is the sand sample, and composition mostly is the earthy thing of shale particle greatly.The phosphorus ore thing is based on apatite, and gangue mineral mainly contains vesuvian, calcite, quartz, muscovite, biotite, allochite etc., and wherein in the majority with calcite, other mineral are then rarely found.See landwaste and metalliferous mineral are arranged.Landwaste roughly has three kinds: a kind ofly be made up of clay mineral, shale, sericite and biotite, wherein biotite is less relatively; Another kind of landwaste is entirely by micro-lepidiod bauxite rock landwaste; The third landwaste is limestone landwaste (more rare).Metalliferous mineral has limonite and a small amount of magnetic iron ore, and magnetic iron ore is that subhedral is crystalline sometimes, is xenomorphic granular sometimes.Limonite then is irregular granular.This mine tailing phosphorus grade is low, be about about 18.56%, the difficult choosing of some phosphorus ore thing, argillization is more serious, at mog is that 200 orders accounted for 70% o'clock, found that in floatation process, adopt soda ash, waterglass to size mixing separately, when using oxidized paraffin wax soap to carry out flotation, find that the soda ash consumption is when 15kg/t, flotation effect is relatively good, but concentrate foam viscosity is big, is difficult to sedimentation.And use this combined modifier CS to be about 4kg/t, proportioning is: sodium carbonate: salt: caustic soda: waterglass=2: 0.2: 0.8: 1.Adjust the agent consumption and reduce to about 4kg/t, concentrate grade can be brought up to more than 30%, and the rate of recovery can reach more than 40%, and the concentrate effect of settling is relatively good.Use according to this ore facts have proved, the flotation of such phosphorus ore thing is had well size mixing and, because the use of this combination medicament can reduce the consumption of adjusting agent, be convenient to the collecting of collecting agent simultaneously the inhibitory action of gangue.Because these combined modifier raw material sources are wide, moderate, and market popularization value is arranged.
