Description
Technical field
The present invention relates to a kind of floating agent for improving Sphalerite flotation index, belong to metallic ore ore dressing field.
Background technology
The separation of complicated sulfuration mine is the great difficult problem of China's non-ferro metals floatation technique, with resource dilution, be result in
Pharmaceutical quantities consumed in the ore of poor, thin, miscellaneous, difficult choosing are continued to increase, but floatation indicators fail have more obvious improvement.It is domestic
Collecting agent of the xanthate as zincblende is continued to use always, although can obtain preferable effect to a certain extent, but for microfine
Zincblende, the selectivity of its xanthate shows slightly not enough.The development direction of new medicament should have preferable collecting mainly for xanthate
Effect, but selectivity problem on the weak side.In face of increasingly complicated mill head property, the country lacks for fine fraction zincblende
The floating agent for sorting, in order to solve this problem, is badly in need of the most efficient flotation reagents that exploitation is sorted for fine fraction zincblende.
The content of the invention
In order to solve the problems, such as that fine fraction zincblende amount of consumption of drugs is big, sorting result is poor, it is an object of the invention to provide one kind
Sphalerite flotation medicament, the rate of recovery to zinc is high, and consumption is few, low cost, more obvious to fine fraction zincblende sorting result.
The technical proposal for solving the technical problem of the invention is：The special floating agent is by concentration 8~10wt% ethyls
Sodium xanthogenate solution, 8~10wt% butyl xanthic acids sodium solution, 8~10wt% amylic sodium xanthogenates solution and the fourths of 1~1.5wt% bis-
Base phosphordithiic acid ammonium salt solution is mixed, and the percent by volume of four kinds of solution is that 5~20 parts of ammonium dibutyl dithiophosphates are molten
Liquid, 5~15 amylic sodium xanthogenate solution, 30~40 ethoxy-dithioformic acid sodium solutions, balance of butyl xanthic acid sodium solution.
The assistant medicament used cooperatively with the floating agent is copper sulphate and 2# oil.
The beneficial effects of the invention are as follows:The medicament can reduce the metal loss of zincblende in mine tailing, improve zincblende and reclaim
Rate（Zinc recovery can improve 1%~3%）, reagent consumption is relatively low（Only the 1/3 of conventional dose）, and prepare it is convenient, using simple,
Only medicament according to certain ratio be simply mixed treatment and can be used for zincblende and sorted, can significantly reclaim fine fraction（-
500 mesh）Zincblende, improves zinc metal recovery rate.New medicament of the invention for floatation process have obvious technical indicator advantage,
Economic effect and environmental benefit.
Specific embodiment
The present invention is described in further detail below in conjunction with specific embodiment
Its each solution concentration of formula of the invention：8~10%（wt）Sodium ethylxanthate, 8~10%（wt）Sodium n-butyl-xanthate, 8~
10%（wt）Amylic sodium xanthogenate, 1~1.5%（wt）Ammonium dibutyl dithiophosphate.
The preparation method of the medicament is, according to above-mentioned formulation content, by above-mentioned 4 kinds of raw materials, to be configured to corresponding concentration,
Ratio according to above-mentioned technical proposal mixes.
The application method of medicament is the solution prepared in a manner described, and the medicament of the preparation directly adds floating for zincblende
It is elected to be the roughing operation in industry.
The percent by volume of each component solution of 1 embodiment of table 1~4
。
According to the proportions medicament in above table, wherein：5~20 parts of ammonium dibutyl dithiophosphate solution, 5~15
Amylic sodium xanthogenate solution, 30~40 ethoxy-dithioformic acid sodium solutions, balance of butyl xanthic acid sodium solution make total to reach percentage
Hundred.
The application method of medicament is the solution prepared in a manner described, and it is thick that the medicament of the preparation is directly made an addition into zincblende
Industry is elected to be, the collecting effect of zincblende is played in floatation process, and the floating agent is efficient（The zincblende rate of recovery is carried
It is high by 1%~3%）, consumption it is few（Only the 1/3 of conventional dose）, it is especially more obvious to fine fraction zincblende sorting result.
The present embodiment 1~4 is the mine tailing after lead sulphur mixes choosing, and into zinc Beneficiation flowsheet, its zincblende grade is not quite similar.
2 are shown in Table using the technological process of example 1~4 of collecting agent of the present invention and conventional dose and conditional outcome contrast.Therefrom
Find out, compared with conventional dose condition, new medicament condition test of the invention its zincblende rate of recovery is respectively increased 2.57%,
1.49%th, 2.31%, 2.21%, new medicament of the invention is remarkably improved Sphalerite flotation index, and dosing is few.
The floatation indicators of 2 embodiment of table 1~4 are contrasted
。
Embodiment 5~8：
The present embodiment 5~8 is different fineness（It is i.e. different less than 0.025mm contents）Under the conditions of lead sulphur it is mixed select mine tailing, as this
The mill head of agentia condition experiment, its technological process is ibid.Using collecting agent of the present invention and the example 5~8 pairs of conventional dose
Than the results are shown in Table 2.Therefrom find out, compared with conventional dose condition, new medicament condition test of the invention its zincblende rate of recovery
1.15%, 2.71%, 2.69%, 2.80% is respectively increased, new medicament of the invention can improve fine fraction Sphalerite flotation index, and medicine
Agent consumption is few.
The floatation indicators of 3 embodiment of table 5~8 are contrasted
。
In embodiment 1~8, different mill head grades, different mill head grade compositions is respectively adopted, carries out ore dressing pair
Than, in ore-dressing technique, by this medicament as zincblende collecting agent, zinc tail detached job can only with one roughing
Reach zinc concentrate grade requirement.
In new medicament application of the present invention to production practices, the zincblende rate of recovery and uses traditional medicament phase up to 93.69%
Than its zinc recovery improves 1.85%, while dosing is by 850g/t, is reduced to 280g/t, saves medicament 570g/t.
