Abstract
The present invention provides a kind of method using tragacanth separation chalcopyrite and talcum, belongs to copper sulfide mineral and hydrophobic silicon hydrochlorate gangue sorts field.This method is levigate by chalcopyrite, talcum, chalcopyrite and talcum is taken to be put into the flotation cell of hanging trough flotator, suitable quantity of water is added and stirs and sizes mixing, the pH of ore pulp is adjusted with pH regulator, No. 2 inhibitor tragacanth, collecting agent butyl xanthate, foaming agent oil are added and stir 1-5min, air flotation obtains concentrate and tailings product, by product drying, weighing, chemical examination.Highly efficient depressor tragacanth can be adsorbed on hydrophobic silicate gangue surface, so that selective inhibitory is generated to hydrophobic silicon hydrochlorate gangue, while medicament is nontoxic, degradable, it is at low cost.
Description
Technical field
The present invention relates to copper sulfide mineral and hydrophobic silicon hydrochlorate gangue sorting technology field, particularly relate to a kind of utilize Radix Astragali
The method of glue separation chalcopyrite and talcum.
Background technique
Copper resource is one of the important foundation raw material being most widely used in the national economic development, is widely used in electricity
The fields such as gas, light industry, machine-building, building industry, national defense industry are only second to aluminium in the consumption of China's nonferrous materials.
China is copper resource big country, but the consumption figure growth rate of copper is significantly greater than production increase speed in recent years.With communication, electric power
The quickening of equal infrastructure constructions and automobile and IT product it is universal, demand of the China to copper products will continue from now on
It increases substantially.But with a large amount of exploitations of resource, the increasingly poor thin hydridization of copper resource brings shadow to efficient utilize of copper resource
It rings.The sorting of talcose copper-sulphide ores is the generally acknowledged technical problem of ore dressing field, and domestic and international researcher carries out such ore
Numerous studies.
The mineral for needing to recycle in talcose copper-sulphide ores are chalcopyrites, and the mineral for needing to inhibit are talcums.When ore dressing,
Since gangue mineral talcum hardness is lower, and there is native floatability, leads to the presence of a large amount of easily floating sludges in flotation pulp, be easy
It floats and enters concentrate, influence the raising of concentrate grade.Therefore, there are two types of approach for the separation of chalcopyrite and talcum: by taking off in advance
Fender removes microfine talcum flotation chalcopyrite again；Add talc depressants and then again flotation chalcopyrite.
It is removed in advance using the physical property and flotation characteristic of talcum, can be with separate section talcum, but this is often
Chalcopyrite is caused to lose.Moreover, can not reach copper sulfide concentrate requirement only with the method for preparatory removing talcum, still need
Carry out the inhibition work of talcum.Inhibit the talcum with native floatability using inhibitor, is in chalcopyrite and talcum separation
Common method, but existing inhibitor also can generate inhibiting effect to chalcopyrite while inhibiting talcum, lead to brass
Mine and the talcum efficiency of separation are lower, are unfavorable for the efficient utilization of copper-sulphide ores resource.Therefore, exploitation has compared with high selection talcum
Property inhibitor, study its inhibiting effect to chalcopyrite and talcum, realize efficiently separating for talcum and chalcopyrite, it is difficult to realizing
Efficient utilize of processing copper-sulphide ores is of great significance.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of methods using tragacanth separation chalcopyrite and talcum, solve
The technique of preparing problem that copper sulfide mineral chalcopyrite can not be separated with talcum efficient flotation separation.
The method includes the steps of:
Chalcopyrite and talcum mixture material is levigate, take it is levigate after raw material be put into the flotation cell of flotation device, add water
And uniform ore pulp is stirred to get, the pH of gained ore pulp is adjusted with pH regulator, and inhibitor tragacanth is then added and stirs 3-
5min, it continuously adds collecting agent butyl xanthate and stirs 3-5min, be eventually adding No. 2 oil of foaming agent and stir 1min, air flotation,
Product in flotation froth and slot is obtained, flotation froth is chalcopyrite, and product is talcum in slot.
Wherein, chalcopyrite purity is greater than 95% in talcose chalcopyrite raw material.Raw material is levigate to granularity less than 74 μm.Match
When setting ore pulp, the mass ratio of raw material and water is 1:(10-40).
PH regulator is hydrochloric acid or sodium hydroxide, and pH values of pulp is adjusted to 5-8.
Inhibitor tragacanth is configured to the solution that concentration is 1%-3% and adds, dosage 100-400mg/L；Collecting agent fourth
Xanthate is configured to the solution that concentration is 5%-10% and adds, dosage 20-40mg/L；No. 2 oil of foaming agent directly add, and dosage is
10-20mg/L。
The advantageous effects of the above technical solutions of the present invention are as follows:
In above scheme, using tragacanth as inhibitor, polymeric inhibitor tragacanth can be adsorbed on hydrophobic silicon
Hydrochlorate gangue talcum surface can be realized sulphur to generate stronger selective inhibitory to hydrophobic silicon hydrochlorate gangue talcum
Change the FLOTATION SEPARATION of copper mineral chalcopyrite and hydrophobic silicon hydrochlorate gangue talcum, while tragacanth extracts from plant, nontoxic, source
Extensively, at low cost, remarkable in economical benefits.
