Abstract
The invention relates to a direct flotation method of zinc sulfide ore. The method includes the steps of grinding the zinc sulfide ore to form ore pulp, adjusting the PH value of the ore pulp to reach 6-11, adding N-alkyl dithiocarbamic acid sodium as a collecting agent and terpenic oil as a foaming agent into the ore pulp, adding zero or little copper sulfate as an activating agent and carrying out flotation. According to the method, copper activation-free direct flotation of the zinc sulfide ore can be realized, the use amount of copper sulfate can be remarkably lowered, and subsequent flotation separation of zinc sulfide and other metal sulfide ore can be promoted.
Description
Technical field
The present invention relates to a kind of zinc sulfide mineral direct flotation method, it is possible to achieve zinc sulfide mineral no member directly
Flotation, belongs to Mineral Processing Engineering field.
Background technology
China's zinc resource enriches, and zinc reserves occupy the 2nd, the world, and industrial 90% about zinc yield derives from zinc sulfide ore
Thing, sphalerite and marmatite are modal zinc sulfide minerals in nature.In nature, pure sphalerite is less, great majority
Sphalerite generally all contains part iron tramp, when in sphalerite, iron content is referred to as marmatite when being more than 6%(ZnxFe1-xS),
It is referred to as superelevation marmatite when iron content is more than 20%.The color of sphalerite be decided by lattice the species of impurity element and
Content, the higher sphalerite color of usual iron content is deeper, and purer sphalerite is in then light yellow.Additionally, sphalerite and ferrum dodge
Also tend in zinc ore containing Determination of Rare-Expensive Elements such as indium, germanium, galliums.Therefore, zinc sulfide mineral also becomes recovery rare precious metal unit
The important carrier mineral of element.However, compared with other several nonferrous metal sulfide minerals, zinc sulfide mineral native floatability is poor,
Especially marmatite is difficult to the xanthate collectors direct flotation with short carbon chain.Therefore, the preactivated one-tenth of zinc sulfide mineral
For necessary link, produce upper widely used copper sulphate for activation at present(200~1000g/t)Use xanthate class flotation more afterwards, that is, activate
Xanthate floatation.But, sphalerite copper sulphate for activation xanthate flotation there is also some unsatisfactory shortcomings:
(1)The copper sulfate marmatite relatively low to sphalerite and some iron-holder has good activation effect, but is as
The increase activation of sphalerite iron content becomes more and more difficult and activator consumption and is significantly increased, and the activation to marmatite is past
Toward not reaching preferable activation effect;
(2)Practice have shown that, secondly the sphalerite after copper sulphate for activation is difficult to be suppressed, and, copper sulfate is as the one of ore dressing field
Plant wide spectrum activator and also a certain degree of activation can be caused to other nonferrous metal sulfide minerals or even gangue mineral, these factors make
Obtain sphalerite and separate extremely difficult, such as copper-znic separation, Pb-Zn separation etc. with other metal sulfides, cause zinc concentrate grade not
High and metal mutually contains problem;
(3)The interpolation of copper sulfate undoubtedly increased beneficiation cost.
For these reasons, the present invention provides a kind of direct flotation method of simple zinc sulfide mineral, using this
Method can realize the no member direct flotation of zinc sulfide mineral or the consumption significantly reducing copper sulfate.Due to there is no copper sulfate
Activating effect, this method for floating is advantageous to the FLOTATION SEPARATION of zinc sulfide ore and other metal sulfides.
Content of the invention
It is an object of the invention to provide a kind of method of zinc sulfide mineral direct flotation, methods described need not be member,
Or significantly reduce the consumption of copper sulfate.
The present invention is achieved through the following technical solutions:
A kind of method of zinc sulfide mineral direct flotation, through following steps:Sulfuration zinc ore crude ore grinding is made weight percent dense
Spend the ore pulp for 25 ~ 40%, the mass percent that wherein breeze of -0.074mm accounts for total breeze is 80~95%, so that mineral composition is filled
Divide monomer dissociation, add acid or aqueous slkali to adjust pH values of pulp to 6 ~ 11, then press the consumption addition collecting of raw ore 50 ~ 100g per ton
Agent stirring action 2 minutes, then add terpenic oil foaming agent stirring action to start after 2 minutes by the consumption of raw ore 20~30g per ton
Flotation.
In described sulfuration zinc ore crude, zinc grade is 1~6%, and in zinc sulfide mineral, iron content is less than 15wt%.
Described bronsted lowry acids and bases bronsted lowry solution is respectively hydrochloric acid and aqua calcises.
Described collecting agent is N- alkyl nabam, and its molecular structural formula is as follows:
In formula, X represents the alkyl of 4~12 carbon atoms, and in alkyl X, the particular number of carbon atom can be specifically right according to ore dressing
As experiment determines.
Select complex ore can also add a small amount of copper sulfate for indivedual difficulties(<100 g/t)This collecting is reused after activation
Flotation.
The present invention has the advantages that:
(1)Depending on original ore property, need not be member or substantially reduce copper sulfate consumption using the method flotation sphalerite, eliminate or aobvious
Write and alleviate the series of problems bringing using copper sulphate for activation;
(2)Compared with traditional copper sulphate for activation xanthate floatation, this direct flotation method has selectivity height, collector dosage
Less, the features such as flotation speed is fast, flotation flowsheet is simple, especially very weak to pyrite collecting ability be conducive to zinc sulphur content from.
