Description
Technical field
The present invention relates to zinc ore flotation beneficiation technology and application field, particularly a kind of flotation for oxidized form zinc ore
Medicament and method for floating.
Background technology
Zinc is one of important nonferrous metal ore, be widely used in zinc silk, zine plate, zinc powder, plating, fax version, kill
Worm agent and alloy etc. are applied, and the application of zinc at this stage has irreplaceability.Zinc ore is the mineral resources formed by geologic process,
With non-renewable.The zinc deposit that geologic process is formed can typically be divided into vulcanization type (i.e. primary type) and oxidized form (i.e. wind
Change type), wherein, for vulcanization type zinc ore mainly based on zincblende (ZnS), it is the mineral that flotation is most difficult in sulfide mineral,
But it can also show good floatability after the potassium permanganate by adding a certain amount of concentration in ore pulp, pass through flotation work
Skill can reach the higher rate of recovery, therefore vulcanization type zinc ore is always the essential mineral of zinc ore industry, and utilization are preferable；Oxidation
Type zinc ore is the secondary ore of zinc, is a kind of important zinc-bearing mineral, mainly with smithsonite (ZnCO3), smithsonite [Zn2(Si2O7)
(OH)·H2O], willemite (ZnSiO4), zincite (ZnO), marionite [Zn5(CO3)2(OH)6] etc. form exist, containing a large amount of
Metal impurities, such as lead, iron, cadmium, copper, gold, silver, this kind of more metal chapeau de fers belong to difficult using one of ore (difficult ore dressing), this
The utilization of class difficulty ore dressing primarily directed to association in such ore noble metal, and zinc and other association components not yet completely profit
With, that is to say, that there is presently no preferable Application way for oxidized form zinc ore.
With the development and modernization construction of society, the mankind are more and more to the demand of zinc and consumption, the exploitation speed of zinc ore
Degree is also increasingly faster, and with continually developing with exhausted for China's vulcanization type zinc resource, be easy to utilize has industry meaning at present
The vulcanization type zinc ore of justice is fewer and fewer, and zinc resource shortage contradiction is more and more prominent, forces people to have to turn to more difficult utilize
Oxidized form zinc ore, the utilization to oxidized form zinc ore are also increasingly taken seriously, but the utilization of oxidized form zinc ore always one
Problem.The processing mode of oxidized form zinc ore has two kinds：First, enter back into smelting program after oxidized form zinc ore is carried out into beneficiation enrichment
To obtain metallic zinc；Program processing is smelted to obtain metallic zinc second, oxidized form zinc ore is directly entered.Due to oxidized form zinc ore
Stone grade is relatively low, complicated component, and when such ore directly being entered into smelting program, the difficulty of recycling is very big, production
Cost is of a relatively high.Therefore, the processing mode of oxidized form zinc ore enters back into smelting program after mainly carrying out beneficiation enrichment, with drop
Low smelting cost.Flotation is to handle the major way that oxidized form zinc ore carries out beneficiation enrichment, and the important directions of beneficiation research.
So far, the method for floating of oxidized form zinc ore is in addition to bulk flotation, also dense media-floatation, magnetic-floating flow the methods of, but
It is that its mineral processing index is all not so good, the rate of recovery of its zinc is only 60%-70%, and the zinc concentrate grade that can be obtained is only 30%-
40%.
The content of the invention
The difficulty that the present invention has recycling for the method for floating of oxidized form zinc ore in the prior art is big, production cost
It is of a relatively high, and the rate of recovery of zinc is low, a kind of problems such as the zinc concentrate grade of acquisition is low, it is proposed that oxidized form zinc ore floating medicine
Agent, different floating agent weight meter combinations and addition sequence are used for the oxidized form zinc ore of diverse geographic location, is reached
The purpose of effective enrichment zinc ore has been arrived, has improved the utilization rate of zinc ore, the rate of recovery of zinc and zinc concentrate grade.The present invention is also
It is related to a kind of oxidized form zinc ore floating method.
