Description

A kind of copper-cobalt ore strengthens the method that suppression copper carries molybdenum
Technical field
The present invention relates to the copper-cobalt ore method in minerals separation field more particularly to a kind of sides for strengthening suppression copper and carrying molybdenum Method.
Background technology
Copper-molybdenum ore reserves is very big in the world, and the copper-molybdenum in China is in the high_speed development stage, time for molybdenum in copper mine It is always a bigger problem to receive.The few technique streams using diffeential floatation of the Beneficiation flowsheet of copper-molybdenum ore at present Journey, mainstream sorting process are copper-molybdenum bulk flotation, and copper-molybdenum bulk concentrate presses down process for copper by floating molybdenum and carries out copper-cobalt ore, copper-molybdenum point It is molybdenum concntrate from flotation froth, flotation tailing is copper concentrate.
Due to the very difficult inhibition of the secondary copper ores such as the bornite in floatation process and vitreous copper, floated using conventional suppression copper Molybdenum technology, technic index is difficult to control, the rate of recovery and product quality fluctuation are big.In addition it is big in bulk concentrate during copper-cobalt ore Interference can be generated to separation by measuring gangue mineral, and containing a large amount of shale mineral especially in China's low-grade copper molybdenum ore, this is right Copper mineral is effectively inhibited to propose higher requirement in copper-cobalt ore technique.
Invention content
The present invention provides a kind of copper-cobalt ore and strengthens the method that suppression copper carries molybdenum, strengthen during copper-cobalt ore inhibit it is secondary Copper mineral, while the recycling of molybdenum ore object is improved, it ensure that the grade and the rate of recovery of molybdenum concntrate.
The technical solution adopted by the present invention is that:Include the following steps:
A. copper-molybdenum bulk concentrate by coarse scan select in advance throw tail, one roughing, scan three times with five times it is selected after obtain essence Ore deposit foam;
B. copper deactivator is added in the concentrate foam obtained in step a;
C. the ore pulp formed in step b enters grinding machine and regrinds;
D. molybdenum collecting agent is added in the ore milling product obtained in step c;
E. the product that step d is obtained enters essence six to smart ten flotation operations, obtains final copper concentrate and molybdenum concntrate.
Tail is thrown in the step a in advance to include primary pre- roughing and scan in advance three times.
Copper deactivator is sulfur hydrogen salt class inorganic salts in the step b, and dosage is 180~220g/t bulk concentrates.
It is NaHS that copper deactivator, which is sulfur hydrogen salt class inorganic salts, in the step b.
In the step c grinding machine be tower grinding machine, ore milling concentration 10%-12%.
Molybdenum collecting agent is non-polar hydrocarbon oil in the step d, and dosage is 480~520g/t bulk concentrates.
A kind of copper-cobalt ore disclosed in this invention strengthens suppression copper, and to carry molybdenum methodological science reasonable, easy to operate, it is easy to accomplish, It has the following advantages compared with prior art:
1. the inhibition in efficient hardening copper-molybdenum bulk concentrate separation process to copper mineral, especially efficiently solves secondary The unquenchable problem of copper mineral, and then improve molybdenum concentrate grade and the rate of recovery.Usually add in copper-molybdenum bulk concentrate separation process NaHS is added to inhibit as copper mineral, the HS that NaHS is dissociated in ore pulp and generated-、S2-It can adsorb in chalcopyrite Surface, prevents chalcopyrite and collecting agent phase separation, and mineral are suppressed due to surface hydrophilic ion.However in copper-molybdenum bulk concentrate still Containing a certain amount of secondary pig copper, there are passivation phenomenons on secondary pig copper surface, its hardly possible is caused to inhibit hence into molybdenum concntrate, leads to molybdenum Concentrate grade is difficult to reach sale requirement.In technical solution disclosed by the invention, copper suppression is added in smart five foam grinding processes Preparation, smart five foams can generate a large amount of fresh surfaces in grinding process, and fresh surface is in the moment meeting of formation and copper deactivator Interaction, so as to eliminate secondary copper surface passivation phenomenon, enhances the inhibition to copper, so as to improve the grade of molybdenum concntrate.
2. smart five foam regrinding process avoid bulk concentrate argillization problem, while enhance selected foam reagent removal, after being Continuous operation prepares qualified molybdenum concntrate and provides guarantee.To the 5th selected foam of copper-cobalt ore in technical solution disclosed by the invention Regrinded rather than bulk concentrate detach at the beginning of regrinded, this is because copper-molybdenum bulk concentrate by pre- coarse scan choosing, coarse scan Choosing and five times it is selected after deviate from most gangue quartz impurity, while ensureing that copper and molybdenum effectively dissociate, avoid gangue A large amount of crush of class mineral and the argillization phenomenon generated, in addition smart five foams deviate from the xanthate of a large amount of remainings in grinding process Class collecting agent prepares qualified molybdenum concntrate for subsequent job and creates condition.
3. regrinding before product enters downstream and being added to collecting agent of the non-polar hydrocarbon oil as molybdenum, follow-up work is enhanced Recycling of the industry to molybdenum improves the rate of recovery of molybdenum.In technical solution disclosed by the invention kerosene, essence five are added to regrinding product Copper-molybdenum intergrowth can be dissociated accordingly during foam is regrinded, and kerosene can be made with newly-generated molybdenum ore object monomer surface at this time With enhancing the recycling of this part molybdenum ore object, improve the rate of recovery of molybdenum concntrate.
4. technical solution operation disclosed by the invention is easy, equipment investment and power consumption are small, remarkable in economical benefits.This hair The core technology that a kind of bright disclosed copper-cobalt ore reinforcing suppression copper puies forward molybdenum method is by being added during being regrinded to smart five foams NaHS enhances the inhibition to copper mineral, while ensureing that copper is effectively dissociated with molybdenum, avoids a large amount of of gangue quartz mineral In addition the argillization phenomenon for crushing and generating enters before downstream to regrinding product and is added to kerosene, enhances subsequent job pair The recycling of molybdenum improves the rate of recovery of molybdenum.Therefore the technical solution is easy to operate, is not required to larger equipment investment and power disappears Consumption, operating cost are low, it is easy to accomplish.
