Description
Technical field
The present invention relates to a kind of method activated in ore sulfide flotation system, more particularly relate to activate and adjust in a kind of cupric oxide ore sulfide flotation process the method for mineralized froth, belong to ore dressing field.
Background technology
In the method for floating of cupric oxide ore, most important method is that to vulcanize the xanthate floatation be basic framework.If flotation effect is not good enough, its reason can be analyzed from following angle, on the one hand from the purpose mineral, higher in conjunction with the ratio of copper, chrysocolla, intergrowth and microfine; From non-purpose mineral, harmful sludge content is on the high side on the other hand.For the former, can strengthen collecting by the method that adds activator, activator commonly used has ammonium salt, ethylenediamine, dithiol thio biphosphole etc.; For the latter, should manage to eliminate the impact of sludge.For the cupric oxide ore containing mud, if above two kinds of means use will both will be found out to the best activator of effect, can when using this activator, manage to eliminate the impact of sludge again.
When by sulfuration xanthate floatation, processing cupric oxide ore, because the copper sulfide film on copper oxide mineral surface easily comes off, the oxygen that whipping process is brought in addition makes partial vulcanization agent oxidation deactivation, so the flotation speed of copper oxide mineral is slower, the coarse scan selections number of flotation is more, vulcanizing agent needs segmentation to add, and can also stablize the copper sulfide film on copper oxide mineral surface with activator, makes it be not easy to come off.
By existing sulfide flotation method and sulfuration active flotation method, each section selected in coarse scan to flotation, due to the same operation of it being seen as to floating similar mineral, although so adopted different regime of agent, but its difference is less, only show as in the design of testing program the flotation to first paragraph and find best medicament condition, each section flotation afterwards carried out to medicament according to the first paragraph flotation to be added, its mineralized froth feature similarity, just the mineralized froth amount is by changeable few, the regime of agent of drafting thus is for only changing the dosing of back segment, do not change kind and the effect of medicament, more can not consider the difference of mineralized froth feature.Therefore in the technology of existing processing cupric oxide ore, still sulfide flotation method and sulfuration active flotation method are not combined, be applied to the front and back section of same flotation circuit; The example also activator and mineralized froth adjusting agent are not used in conjunction with.
Summary of the invention
It is research object that the present invention be take containing the mud cupric oxide ore, for the activation problem in the sulfide flotation system, coarse scan selections number with its flotation mostly is point of penetration, it is divided into to last stage flotation and after-stage flotation, and the larger regime of agent of difference before and after for this reason designing, before and after making, the flotation in stage forms different mineralized froth features, realizes different flotation purposes.
To containing finding in the experimental study process of mud cupric oxide ore, if add at the very start activator, with not adding activator, compare, at limited first paragraph, roughly select or first paragraph is roughly selected and added second segment and roughly select in the time, can make copper recovery and concentrate grade all descend.Analyze such result of the test and corresponding mineralized froth feature, think that this is the interaction due to various medicaments and sludge, cause too early the foam cavitation degree higher and make activation effect be difficult to present.
The present invention realizes by following technical proposal: a kind of method of activation and adjustment mineralized froth in cupric oxide ore sulfide flotation process, comprise last stage flotation, after-stage flotation, selected, described last stage flotation comprise one section roughly select or one section roughly select with two sections and roughly select, totally 1～2 segmentation; Described after-stage flotation comprises roughly selecting and scanning after the last stage flotation, totally 4～7 segmentations, and described selected totally 1～2 segmentation, specifically pass through following each step:
A. the cupric oxide ore wet-milling is made to ore pulp;
B. steps A gained ore pulp is carried out to the last stage flotation, in each segmentation of last stage flotation, add respectively vulcanizing agent 800～1500g/t raw ore, add collecting agent 60～200g/t raw ore, add foaming agent 20～50g/t raw ore;
C. step B gained ore pulp is carried out to the after-stage flotation, each segmentation in the after-stage flotation adds respectively mineralized froth adjusting agent I 0～400g/t raw ore, vulcanizing agent 200～1500g/t raw ore and activator 200～2000g/t raw ore, add again collecting agent 30～100g/t raw ore and foaming agent 10～30g/t raw ore, wherein, the activator that the mineralized froth adjusting agent I that first segmentation adds is 100～400g/t raw ore, add is 1000～2000g/t;
D. to the froth pulp of step C gained after-stage flotation or the mixture of steps A gained last stage flotation froth product and step B gained after-stage flotation froth product is carried out selected, in each selected segmentation, add respectively mineralized froth adjusting agent II 0～100g/t raw ore, vulcanizing agent 200～600g/t raw ore and collecting agent 20～60g/t raw ore.
The vulcanizing agent of described step B, C and D is one or more (any mixture, lower with) in vulcanized sodium, NaHS, sodium polysulfide.
The activator of described step C is one or more in ammonium sulfate, ammonium carbonate.
The mineralized froth adjusting agent I of described step C is one or more in calgon, carboxymethyl cellulose, waterglass.
The collecting agent of described step B, C and D is one or more in butyl xanthate, isoamyl xanthate, isopropyl xanthate.
The foaming agent of described step B and C is conventional foaming agent, as No. 2 oil.
The mineralized froth adjusting agent II of described step D is one or more in kerosene, diesel oil.
The present invention will add the period of activator to change into the after-stage of flotation, compare mutually, larger to the accumulation rate of recovery increase rate of copper, illustrate that activation effect can present in the after-stage flotation.For fear of only adding, the foam volume that activator causes is excessive, in the after-stage flotation, activator and mineralized froth adjusting agent I are used in conjunction with, although add a small amount of mineralized froth adjusting agent I, to copper, slight inhibitory action is arranged, but the increase rate to copper recovery is still larger, volume and the water content of mineralized froth have been reduced again simultaneously, so not only be convenient to the bubble of scraping of after-stage flotation, also be convenient to introduce selected by the flotation froth of after-stage.
Compared with prior art, the present invention has following advantage:
1, the activation effect of activator before stage flotation whether to add the difference of the rate of recovery after activator be criterion, and will promote as criterion by the accumulation rate of recovery of all stage flotations, leak with regard to having avoided last stage flotation activation effect to be difficult to present like this and select activator;
2, when the after-stage flotation adds activator, also coordinate and add mineralized froth adjusting agent I, can cause foam volume excessive when avoiding only adding activator, be convenient to like this production operation;
3, adopt flowage structure of the present invention and adding method thereof, not only, to ore milling product predictive desliming not, directly enter flotation, the copper metal loss of having avoided thus desliming to cause; And compare with sulfuration active flotation method with existing sulfide flotation method, when guaranteeing that Cu Concentrate Grade is close, can improve 8～14 percentage points of the copper concentrate rate of recovery.
