Description
Technical field
The present invention relates to a kind of method for eliminating copper ion in secondary copper sulfide polymetallic ore slurry solution, belong to mineral processing
Technical field.
Background technology
The multi-metal sulfide in China, especially cupric multi-metal sulfide, the most disseminated grain size of valuable mineral is thin, copper mine
Thing and other sulfide mineral densification symbiosis.In addition, the oxidation of copper sulfide ore, causes secondary copper sulfide mineral in grinding process to dissociate
Go out a large amount of copper ions.It is single that the diffeential floatation of Cu, Pb, Zn, Fe sulphide ore is unchallenged from the point of view of minal flotation, but
In actual production, copper ion has activation to sulfide minerals such as zincblende, need to add regulator, could realize separation, but
Reagent consumption amount is big, and the floatation indicators of final concentrate are not high, and economic benefit is low.
Cu2+The mechanism of activation to zincblende：
The standard free energy of the reaction, which becomes, to be turned to：
Activate the Cu needed for zincblende2+Concentration and Zn2+The ratio between concentration is：
Similarly, the Cu needed for pyrite is activated2+Concentration and Fe2+The ratio between concentration is：
Thermodynamic data is looked into, calculates Cu2+To zincblende and pyrite priming reactionAnd required concentration：
Cu2+Activate zincblende, the condition of pyrite
At present, Na is used mostly to the polymetallic ore containing secondary copper sulfide both at home and abroad2S、ZnSO4、Na2SO3Suppress zincblende
But when secondary copper content is more in flotation system, more copper ion is also easy to produce, is easily formed on galena, zincblende surface
Copper sulfide film, assign their properties of certain similar copper sulfide mineral, cause surface property differences unobvious, can not obtain compared with
Good floatation indicators.K2Cr2O7Galena has certain effect, but easily causes pollutions of the heavy metal ion Cr to environment.Use cyanogen
Change sodium and suppress copper sulfide mineral progress FLOTATION SEPARATION, but Cymag, the potassium cyanide in waste water have severe toxicity, processing cost height.Separately
Outside, in the case where head grade is relatively low, using diffeential floatation or iso flotability flotation, first sulfide mineral is suppressed, meeting
Substantial amounts of inhibitor is consumed, collecting is then activated to it and consumes substantial amounts of activator again, considerably increases industrial cost.
As seen through the above analysis：In the flotation operation of the multi-metal sulfide containing the secondary pig copper, unavoidable ion Cu2+
Generation can to flotation system produce significant impact.Cu is eliminated using rational method2+Influence to flotation operation, turn into raising
One important channel of the multi-metal sulfide mineral processing index containing the secondary pig copper.
The content of the invention
During to overcome existing technique of preparing to handle the multi-metal sulfide containing the secondary pig copper, it is difficult to eliminate Cu2+To flotation system
The shortcomings that having an impact, better profits from the existing multi-metal sulfide resource in China, and the present invention proposes a kind of secondary sulphur of elimination
The method for changing unavoidable copper ion in Cu-polymetallic deposit slurry is specific, specifically includes following steps：
（1）The well mixed preparation suspension of copper powder is added in water in 1 ~ 5 g/L ratio, and is heated to boiling；
（2）Raw ore slurry is prepared to monomer dissociation in polymetallic ore sample ore comminution ore deposit, step is added in raw ore slurry（1）
Obtained copper powder suspension, hydrochloric acid, heating stirring make it fully react the ore pulp after the copper ion that is eliminated；By in sample ore per ton
The ratio for adding 5~20g copper powders adds copper powder suspension in ore pulp；The hydrochloric acid of addition makes the pH of ore pulp be 2~5.
Step of the present invention（1）Described in copper powder granularity be 25~75 μm.
Step of the present invention（2）The mass percent concentration of middle raw ore slurry is the % of 60 %~80.
Step of the present invention（2）Middle hydrochloric acid mass fraction is 20~40 %.
Step of the present invention（2）Described in the reaction time be 10~20 min, heating-up temperature is 40~65 DEG C.
Step of the present invention（2）Ore pulp is prepared conventional flotation is carried out by conventional method, obtain final concentrate product.
The present invention principle be：Hydrochloric acid and copper powder under conditions of heating with Cu2+Reaction, generation Cu (I) complex；The presence that can relatively stablize in aqueous, it is not easy to be disproportionated into Cu2+And Cu.Relevant Element potential diagrams
It is as follows：
, soIn water
It is more stable in solution.Following reaction can be carried out to the right：
The present invention utilizes this principle, eliminates unavoidable ion Cu2+To the adverse effect of flotation system, sudden strain of a muscle is effectively prevented
The formation of the mineral surfaces sulfide film such as zinc ore, galena, pyrite, increases floating between copper sulfide mineral and other mineral
Sex differernce, improve floatation indicators.
Beneficial effects of the present invention are：
（1）Effectively eliminate Cu caused by secondary copper sulfide2+To zincblende, pyrite, magnetic iron ore activation；
（2）The dosing in flotation operation is reduced, has greatly saved cost, essence can be reduced, scan number；
（3）Hydrochloric acid, copper powder source are wide, and action effect is notable, and copper powder can enter concentrate product and be recovered；
（4）The grade and the rate of recovery of copper concentrate are improved, reduces product in concentrate and mutually contains phenomenon.
