Abstract
The invention provides a kind of cyanide and do the method reclaiming copper in the molybdenum cleaner tailings of copper-cobalt ore inhibitor, solve the copper sulfide mineral suppressed by cyanide and be difficult to activation, a difficult problem for recovering effect difference, be conducive to the high efficiente callback of the copper sulfide mineral suppressed by cyanide, it is obtained in that and preferably selects copper index, the present invention is possible not only to reduce the loss of copper resource, and brings certain economic benefit and social benefit to enterprise.
Description
Technical field
The present invention relates to mineral manufacture field, be specifically related to a kind of cyanide and do the molybdenum cleaner tailings of copper-cobalt ore inhibitor
The method of middle recovery copper.
Background technology
Copper-cobalt ore is to annoying the difficult problem that molybdenite produces always, and in molybdenum concntrate, copper content exceeds standard often.Sodium sulfide, mercapto
Guanidine-acetic acid sodium and cyanide all can be as the inhibitor of copper sulfide mineral, wherein with cyanide to the inhibition of copper mineral
Good；Meanwhile, the more difficult recovery of copper sulfide mineral suppressed by cyanide.In the past, the copper content in molybdenite cleaner tailings is little
In 0.1%, synthetical recovery economic benefit is relatively low, and therefore, it is all abandoned by most of Mu Xuan factories, causes the loss of copper resource.
In recent years, exploiting and utilize the continuous expansion of scale along with Mo resource, the simple molybdenum ore easily selected reduces day by day,
The preparation proportion of Refractory molybdenum ore stone lean, thin, miscellaneous will increase year by year, and the intractability of molybdenum ore is also increasing year by year, due to brightness molybdenum
Ore deposit and copper sulfide mineral association relationship altogether is close, and a large amount of copper select in molybdenum rough concentrate with the intergrowth entrance of molybdenum, cause the selected tail of molybdenum
In ore deposit, the copper content in copper sulfide mineral rises to about 0.5%, if it not carried out synthetical recovery, will result in the tight of copper resource
Heavily lose, reclaim the copper sulfide mineral in molybdenum cleaner tailings, it is only necessary to carry out concentrating, flotation, the technical process such as filter and be dried, one-tenth
This is relatively low, simultaneously as copper content is higher in molybdenum cleaner tailings, its synthetical recovery has considerable economic benefit.
Summary of the invention
It is an object of the invention to provide a kind of cyanide and do the side reclaiming copper in the molybdenum cleaner tailings of copper-cobalt ore inhibitor
Method, solves one or more problems in above-mentioned prior art.
The technical solution adopted for the present invention to solve the technical problems:
A kind of cyanide does the method reclaiming copper in the molybdenum cleaner tailings of copper-cobalt ore inhibitor, comprises the steps:
1) the concentration escapes the medicine: the cupric molybdenum cleaner tailings utilizing raker thickener to suppress cyanide concentrates, before concentrating
7%～12%, it is concentrated to 20%～50%；
2) ore pulp after concentrating delivers to agitator dilute, adds copper sulfate, act on 3-10 minute while dilution, dilute
Release rear concentration and be not less than 20%；
3) ore pulp in step 2 is concentrated, introduce after being concentrated to 20～50% in another agitator, and be sequentially added into and catch
Receive agent and foaming agent, collecting agent and foaming agent are respectively xanthate and 2#Oil；
4) stirring ore pulp is in the case of floatation concentration is not less than 20%, use one roughing, four times selected and scan for twice floating
Selecting flow process, can obtain grade is 15%～25%, the copper concentrate of the response rate more than 80%.
Lime consumption in described step 1 is 500～1000g/t to ore deposit, adds Calx and can remove the cyaniding in ore pulp
Thing, to reduce the consumption of follow-up reagent removal agent.
In described step 2, the consumption of copper sulfate is 250～400g/t to ore deposit, adds copper sulfate and can remove copper sulfide mineral
The cyanide of surface adsorption.
Xanthate consumption in described step 3 is 25～40g/t to ore deposit, 2#Oil consumption is 5～15g/t to ore deposit.
Owing to using technical scheme as above, the present invention has a following superiority:
The invention provides a kind of cyanide and do the method reclaiming copper in the molybdenum cleaner tailings of copper-cobalt ore inhibitor, solve by
The copper sulfide mineral of cyanide suppression is difficult to activation, a difficult problem for recovering effect difference, is conducive to the copper-sulphide ores suppressed by cyanide
The high efficiente callback of thing, it is possible to obtain and preferably select copper index, the present invention is possible not only to reduce the loss of copper resource, and gives enterprise
Bring certain economic benefit and social benefit.
Accompanying drawing explanation
Fig. 1 is the flow chart of the present invention.
Detailed description of the invention
Example 1
Henan molybdenum ore use in molybdenite refining process Cyanogran. as the inhibitor of copper sulfide mineral, in molybdenum cleaner tailings
Copper content is 0.48%.
The first step, utilizes raker thickener, adds sedimentation agent and reagent removal agent Calx, the consumption of Calx be 800g/t to ore deposit,
The concentration that molybdenum cleaner tailings is concentrated to 45% carries out reagent removal, dehydration；
Second step, by concentrate ore pulp deliver to No. 1 agitator size mixing to 25% concentration, be simultaneously introduced activator copper sulfate to ore pulp
Carry out reagent removal activation, copper sulfate consumption be 350g/t to ore deposit, action time is 3 minutes；
3rd step, by the pulp conveying of concentration after reagent removal 30% to No. 2 agitator, adds collecting agent and foaming agent, and collecting agent is adopted
With xanthate, foaming agent uses 2#Oil, xanthate and 2#Oil consumption is respectively 35g/t and 10g/t to ore deposit；
4th step, finally by pulp conveying to flotation section, flotation flowsheet be one roughing, four times selected and secondary is scanned, finally
Selected foam is through to filter, can obtain after drying accumulative grade be 20.23%, accumulative theoretical recovery is more than 81.53% copper concentrate.
The optimal way being only the present invention presented above, it is noted that for the those of ordinary skill of the industry, not
On the premise of departing from the invention design, it is also possible to making some deformation and improvement, these also should be regarded as the protection of the present invention
Within the scope of.
