Abstract
A preparation method of an auxiliary collecting agent for improving the recovery rate of associated gold in antimonite comprises the following steps: first mixing oxalic acid, hydrochloric acid and water at a mass ratio of (1-1):(1-2):(2-3) to obtain a solution 1; then adding ammonium phosphate into the solution 1 at a mass ratio of (1-2):(2-5), and performing stirring at 70-75 DEG C to dissolve the ammonium phosphate to obtain a solution 2; and next, adding ammonium sulfolipid into the solution 2 at a mass ratio of (1-2):(1-3), conducting reaction for 2-4 h at 2-2.5Mpa to obtain a liquid agent, namely the auxiliary collecting agent.
Description
One, technical field
The present invention relates to a kind of preparation method improving the supplementary catching agent of the associated gold rate of recovery in stibnite.
Two, background technology
General employing optimum flotation flow process or bulk flotation flow process are reclaimed in the flotation of stibnite and associated gold both at home and abroad at present.Selective flotation flowsheet, i.e. diffeential floatation antimony trisulfide mineral under certain condition, and then flotation gold-containing sulfurating mineral; Bulk flotation flow process adds some medicament under certain condition to make antimony gold floating form bulk concentrate.Although these two kinds of methods can effectively reclaim Sb-Au ore thing, selective flotation flowsheet easily makes gold-carrying minerals in antimony concentrate too much introduce antimony concentrate, reduces antimony concentrate grade and harmful element and exceeds standard, and to adopt after bulk flotation separation process again so general.Bulk flotation generally adopts sulfuric acid or copper sulphate first to activate, and then add xanthate, black powder, sulphur nitrogen etc. and carry out flotation collecting, the flotation recovery rate of sulphide ore is between 86 ~ 91%; But when gold-carrying minerals is mica or quartz and gold content is higher, then adopt above collecting agent then not obvious to the recovering effect of gold, the rate of recovery of gold is only 50 ~ 60%, and its reason is: on the one hand, and mica or quartzy floatability vulcanizate not as other; On the other hand, because mica or quartz are originally as oxide mineral, its floatability is poor; Again, in gold-carrying minerals, iron ion affects its floatability with isomorph existence.How to prepare the supplementary catching agent improving the associated gold rate of recovery in stibnite is the problem that concern is compared in domestic and international ore dressing circle always.
Three, summary of the invention
The object of the invention is to a kind of preparation method improving the supplementary catching agent of the associated gold rate of recovery in stibnite, the supplementary catching agent that the method prepares can improve the rate of recovery of associated gold in stibnite.
The present invention realizes above-mentioned purpose by the following technical solutions: a kind of preparation method improving the supplementary catching agent of the associated gold rate of recovery in stibnite, oxalic acid, hydrochloric acid and water in mass ratio=1 ~ 1:1 ~ 2:2 ~ 3 are comprised the steps: to be mixed to get solution 1, then ammonium phosphate in mass ratio=1 ~ 2:2 ~ 5 are added in solution 1, be stirred under temperature 70 ~ 75 DEG C of conditions and dissolve to obtain solution 2; Then sulphur ammonium fat in mass ratio=1 ~ 2:1 ~ 3 are added in solution 2, under 2 ~ 2.5Mpa condition, react the liquid preparation obtained for 2-4 hour be described supplementary catching agent.
The application of supplementary catching agent in flotation of the associated gold rate of recovery in the raising stibnite be prepared into, actual conditions is: during flotation, and adding sulfuric acid adjustment slurry pH is 6.5 ~ 7; In floatation process, ore ore grinding is dissociated to mineral monomer, then add waterglass 250g/t and make inhibitor, add plumbi nitras 50g/t again, copper sulphate 80g/t makes activator, add butyl xanthate 120g/t, described supplementary catching agent 30g/t again, finally add foaming agent 2# oil 100g/t and collecting is carried out to stibnite and associated gold
The total consumption of described supplementary catching agent is: 30 ~ 40g/t.
During use, described supplementary catching agent stoste is added.
Unless otherwise indicated, percentage of the present invention is mass percent, and each constituent content percentage sum is 100%.
Concrete advantage of the present invention is:
1, the supplementary catching agent adopting the present invention to prepare is soluble in water, and has good selective and resistance to low temperature, can improve the rate of recovery of associated gold in stibnite,
2, dosing is few.
