Abstract
The invention relates to a collecting agent and applications thereof in fine-sized molybdenite flotation. One of the related applications is the application of cross-linking agent Sac100 as the collecting agent. The related collecting agent consists of the cross-linking agent Sac100 and kerosene, and the mass ratio of the cross-linking agent Sac100 to the kerosene is 1.5:(6 to 8). The second related application is the application of the collecting agent in fine-sized molybdenite flotation. When the collecting agent disclosed by the invention is used, the recovery rate of negative 400-mesh molybdenite can be increased by 4 percent on average.
Description
Technical field
The present invention relates to a kind of mineral processing flotation collector, be specifically related to one and be applied to the fine-graded flotation collector of molybdenite sulphide ore.
Background technology
Collecting agent is the most important medicament of flotation production technology.Collecting agent changes solid mineral surface hydrophobic, makes the solid ore particle swum attach to floating agent on bubble.
Traditional molybdenite flotation technique is: ore is through fragmentation, ore grinding, flotation (roughly select+selected).Usually add collecting agent and foaming agent roughly selecting, conventional flotation optimum efficiency carries out fine fraction molybdenite flotation for using YC medicament, and its effect is poor, and the rate of recovery is only about 85%.
Summary of the invention
For defect or the deficiency of prior art, the invention provides the application of crosslinking aid S ac100 as collecting agent.
The invention provides a kind of collecting agent, this collecting agent comprises crosslinking aid S ac100 and kerosene.
Optionally, the mass ratio of described crosslinking aid S ac100 and kerosene is 1.5: (6-8).
For defect or the deficiency of prior art, present invention also offers the application of above-mentioned collecting agent in fine fraction molybdenite flotation.
Fine fraction of the present invention is the molybdenum ore that mog-400 order accounts for 80%.
The invention has the beneficial effects as follows:
Use collecting agent of the present invention, the rate of recovery average energy of-400 order molybdenites improves 4 percentage points, and when the rate of recovery of molybdenum improves 4 percentage points, the consumption of collecting agent of the present invention is suitable with kerosene consumption, called after DY15.
Accompanying drawing explanation
Fig. 1 is molybdenite flotation flow chart, and wherein: K represents concentrate, N represents chats, and X represents mine tailing.
Detailed description of the invention
The present invention uses through Mutiple Choice, attempt through great many of experiments, through contrast polyethylene glycol, acrylic acid, sac100 etc., finally determine to use crosslinking agent sac100 and kerosene to carry out proportioning, repeatedly consumption test determines dosage of crosslinking agent, final effect is: the shortcoming reducing Long carbon chain hydrocarbon ils disperse weak effect, do not reduce hydrocarbon ils in the wetting of molybdenite surface and diffusivity simultaneously, the more important thing is and improve the adsorption capacity of medicament for mineral, use this medicament can improve rate of recovery 2-8 percentage point for fine fraction molybdenite flotation in conventional flotation flow process.
Below the specific embodiment that inventor provides, to be further explained explanation to technical scheme of the present invention.
As shown in Figure 1, what adopt in following examples is flotation process in conventional chamber: sample preparation-ore grinding-flotation.Flotation flowsheet adopts a thick essence.Roughly select flotation time and be decided to be 2 minutes, selected flotation time is decided to be 1 minute.During ore grinding, floating agent is added in ball mill.
Embodiment 1:
Experimental condition: andesitic porphyrite type molybdenite 500g, grade 0.6%, mog-400 order 80%.Roughly select L=1.5 liter, selected L=0.75 liter.Roughly select t=2 to divide, selected t=1 divides.
-400 order molybdenite flotation result of the test tables 1
Know from table 1, DY15 to the collecting ability of molybdenum concntrate, apparently higher than YC medicament.The concentrate rate of recovery reaches 83.58%, and the chats rate of recovery reaches 8.48%, adds up to 92.06%, and uses YC medicament to be only 90.02%, improve 2.04 percentage points under equal conditions.Use polyethylene glycol to do crosslinking agent poor effect, use acrylic acid inoperative as crosslinking agent.
Embodiment 2:
Condition: andesitic porphyrite type molybdenite 500g, grade 0.8%, mog-400 order 80%.Roughly select L=1.5 liter, selected L=0.75 liter.Thick selected t=2 divides, and selected t=1 divides, and mixing time is 1 point, and flow process is with figure mono-, and molybdenite flotation result of the test is in table 2.
-400 order andesitic porphyrite type molybdenite flotation result of the test tables 2
Know from table 2, the collecting ability of DY15 collecting agent to molybdenite is better than YC medicament, and when concentrate grade is suitable, the rate of recovery is high 6.88 percentage points.Use polyethylene glycol to do crosslinking agent poor effect, use acrylic acid inoperative.
Embodiment 3:
Condition: Granite molybdenite 500g, grade 0.8%, mog-400 order 80%.Roughly select L=1.5 liter, selected L=0.75 liter.Thick selected t=2 divides, and selected t=1 divides, and mixing time is 1 point, and flow process is with figure mono-, and granite porphyry molybdenite flotation result of the test is in table 3.
-400 order Granite molybdenite flotation result of the test tables 3
Know from table 3, Granite molybdenite flotation, DY15 collecting agent flotation effect is better than YC medicament equally, and gap is obvious, and the rate of recovery is about high 8.89 percentage points.Polyethylene glycol, acrylic acid all do not reach the effect improving the rate of recovery.
