Description
Technical field
The present invention relates to miscellaneous Lead-zinc mine tailings flotation technology fields, more particularly to one kind is to yellow containing marmatite, high magnetic
The multiple difficulty of iron ore fine grain teeth cloth type selects the beneficiation method of lead zinc sulphur ore.
Background technique
Marmatite (Znx,Fe1-x) S is since the zinc atom on zinc blend lattice is by Fe3+Replace, makes chemical valence and charge
State disequilibrium affects mineral floatability, adsorptivity, oxidation to change mineral lattice hole concentration, electron density
Reducing condition and interfacial electrochemistry reaction.In addition, how much iron-containing marmatite is, except its floatability is influenced, have an effect on magnetic strong
Weak, iron content is higher, magnetic stronger.Magnetic iron ore (Fe1-xS, 0 < x < 0.223) it is that one kind can be with the sulphur of the iron of multi mineral symbiosis
Compound has monocline, six sides, three kinds of rectangle polymorph, common for monocline and hexa-pyrrhotite, not the isomorphous system
The magnetism and floatability difference of magnetic iron ore are larger, different from the separating behavior of marmatite.In China's lead zinc sulphur ore resource
In, in galena, marmatite and the magnetic iron ore as the main purpose ore type of mineral, as each outstanding lead zinc is obtained in the Inner Mongol
Mine, Dachang, Guangxi Pb-Zn deposits etc., the embedding cloth feature of this generally existing mineral of type ore is complicated, valuable mineral disseminated grain size is micro-
Carefully, mineral floating environment is complicated, and marmatite and magnetic iron ore separating effect are poor, and lead and zinc dressing recovery difficult is big, sorting index
It is not ideal enough.But this kind of lead zinc sulphur ore resource reserves are big, and development and application prospect is preferable, realizes this kind of Lead-zinc mine tailings
It efficiently utilizes, is many mines technique of preparing problem urgently to be solved.According to the present invention is exactly a kind of containing marmatite, height
The multiple difficulty of magnetic iron ore fine grain teeth cloth type selects the beneficiation method of lead zinc sulphur ore.
Currently, mainly having for the beneficiation method containing marmatite, magnetic iron ore type intrcate Pb-Zn sulphide ore stone: single floating
Select method and Combination of magnetic separation flotation technique.
(1) single floatation.Generally using lead zinc controling differential flotation process for copper under high alkalinity environment, i.e. plumbum floatation process is added big
Amount lime forms the inhibition to marmatite and magnetic iron ore, selects zinc process to continue to add lime inhibition magnetic iron ore floating, adds
Add copper sulphate for activation marmatite, xanthate does collecting agent to its flotation recovery.But that there are flotation flowsheets is long for the method, and floatation process is not
To stablize, middling cycle amount is big, and the efficiency of separation between lead-zinc-sulphur is low, and product quality is poor (product grade is unqualified sometimes),
Flotation recovery rate is not high, and especially (lime consumption is more than 25kg/t tcrude ore, and copper sulphate dosage is more than greatly for lime and copper sulphate dosage
600g/t tcrude ore) the defects of.
(2) Combination of magnetic separation flotation technique.Rear magnetic technique is floated and first floated after generally including first magnetic, is floated technique after first magnetic and is referred to preparatory removing
Most of magnetic iron ore in ore, to magnetic tailing floatation and recovery of lead zinc；And magnetic technique refers to that preparatory flotation obtains lead, zinc after first floating
Concentrate, after to the magnetic iron ore to float in zinc concentrate using magnetic separation remove, obtain qualified zinc concentrate product.Zinc is dodged for iron content
No matter mine, high magnetic iron ore disseminated grain size micro type lead zinc sulphur ore are existed using magnetic technique after floating or first float after first magnetic
It is mingled with a large amount of marmatites in magnetic iron ore, metal loss is serious, causes zinc flotation recovery rate relatively low, and mineral processing index is poor etc. asks
Topic, and there are beneficiation flowsheets it is long, unstable, operation difficulty is big the disadvantages of.
Summary of the invention
The technical problem to be solved by the present invention is to for containing marmatite, the multiple difficult choosing of high magnetic iron ore fine grain teeth cloth type
Lead-zinc mine tailings, traditional ore-dressing technique sort the outstanding problems such as difficulty is big, the efficiency of separation is low, ore dressing overall target difference, provide
It is a kind of efficiently, stablize, that the efficiency of separation is high, adaptable, sorting index is good is fine for marmatite, high magnetic iron ore is contained

The mine rate of recovery, and obtain the zinc concentrate of qualified high quality.
Second, big around marmatite and PYRRHOTITE BY FLOTATION separating difficulty, the selected bioaccumulation efficiency of zinc is low, concentrate grade is poor
The problems such as, by medicament and the mineral mechanism of action, powder performance screening and minal Study of flotation, have developed efficient magnetic
Pyrite inhibitor XKY-12, it easily generates soluble chelating object in Surface of Pyrrhotite, keeps mineral hydrophilic, while in mineral table
Face is adsorbed, and is desorbed mineral surfaces lyophobic dust (double xanthate, xanthic acid copper), is in addition also accelerated magnetic iron ore
Surface oxidation significantly improves the sorting of marmatite and magnetic iron ore to facilitate the selectivity strength to magnetic iron ore to inhibit
Precision.
Compared with the prior art, the advantages of the present invention are as follows: firstly, creativeness, which proposes, " it is mixed preferentially to float lead-two sections of zinc sulphur
Close roughing-zinc sulphur mixed coarse concentrate regrinding dissociation, reagent removal by active carbon-XKY-12 strengthens zinc sulphur content from selected " ore dressing new technology, solution
The problem that beneficiation flowsheet of having determined is long, ore dressing process is unstable, Zinc Concentrates Quality is poor, recovery rate in ore-dressing is low；Secondly, having invented efficiently
Magnetic iron ore inhibitor XKY-12 solves the problems, such as that marmatite is low with the magnetic iron ore efficiency of separation, separation accuracy is poor.
