Description
Technical field
The invention belongs to Copper-lead mixed concentrate separation ore-sorting field, be specifically related to the separation method of a kind of tennantite and galena.
Background technology
The Mineral separation of Copper-lead mixed concentrate is the most all the popular research direction of dresser author, the most both at home and abroad for copper
The research that lead separates is primarily referred to as Chalkopyrite and separates with galena, and less with the Separation Research of galena to tennantite.
Owing to having difficult floating easily suppression for tennantite relatively Chalkopyrite, therefore black to being associated with arsenic in production practices in early days
The copper of copper mine, lead ore mainly use the method for bulk flotation to obtain a Copper-lead mixed concentrate, then to bulk concentrate by adding
The Severely poisonous reagents such as cyanide carry out pressing down copper and float lead sorting, it is achieved copper, the separation of lead minerals.Continuous recently as environmental protection pressure
Strengthening, this method is gradually pressed down lead and floats copper method and replace, and presses down lead and floats copper and mainly use CMC, starch or bichromate conduct
The inhibitor of galena, but these inhibitor also have good inhibiting effect to tennantite, therefore for higher containing tennantite
Copper-lead mixed concentrate for, its separation index is the most not ideal enough.Therefore, find a kind of environmental protection, efficient tennantite with
The Mineral separation method of galena has the most positive realistic meaning.
Summary of the invention
Present invention solves the technical problem that and be, use inflation to regrind and achieve the selective milling of tennantite and galena；Pass through
Dongting Lake phragmites communis carboxymethyl cellulose and other medicament are carried out interworking, improvement, it is thus achieved that a kind of selectivity preferably modification has
Machine acidity LR inhibitor, it is achieved that the Selective depression to galena；Sieve classification fast-flotation of inflation being regrinded separates
Technique combines, and have effectively achieved the high efficiency separation of tennantite and galena.
In order to reach to solve the purpose of above-mentioned technical problem, the concrete technical scheme that the present invention provides is:
Described tennantite comprises the following steps with the separation method of galena:
(1) inflation is regrinded: is imported in ball mill by Copper-lead mixed concentrate (tennantite and the mixing sample ore of galena), fills
Enter the air of 1 3MPa pressure, ore grinding, abrasive material again must be inflated；Described inflation regrinds material middling particle particle diameter≤0.074mm's
Ore particle accounts for more than the 70% of ore particle gross mass；
(2) sieve classification: material of inflation being regrinded imports high frequency shale shaker and carries out classification, and undersize material is as lead concentrate A, sieve
Upper material enters dosing and sizes mixing operation；
(3) dosing is sized mixing: on-the-sieve material importing agitator step (2) obtained carries out dosing and sizes mixing, at agitator entrance
Place calculates acid LR inhibitor 80 200g of addition by ore pulp amount per ton and obtains dosing ore pulp material；Described acid LR inhibitor
By sulphuric acid and LS mass ratio 1:(3～5 in mass ratio) form, described LS is by sodium radio-phosphate,P-32 solution and carboxymethyl cellulose
1:(1 in mass ratio～6) composition；
(4) fast-flotation separates: dosing ore pulp material step (3) obtained imports pneumatic flotation cell and carries out one section quickly
FLOTATION SEPARATION, the froth pulp of flotation is the black copper concentrate of arsenic, and the material of flotation device bottom land is lead concentrate B；The lead concentrate that will obtain
A mixes as lead concentrate with lead concentrate B, it is achieved tennantite separates with galena.
Preferably, step (2) described high frequency shale shaker is 0.04mm high frequency shale shaker.Described acid LR inhibitor is by sulfur
Acid with LS 1:(3 in mass ratio～5) at normal temperatures stir be obtained by mixing；Described LS is fine with carboxymethyl by sodium radio-phosphate,P-32 solution
Dimension element 1:(1 in mass ratio～6) stir at 45～65 DEG C and be obtained by mixing；Described methylcellulose is with Lake Dongting area, Hunan
The phragmites communis of growth is that raw material fawns light yellow fibrous sprills prepared by method technique through water, and its molecular formula is:
C6H7O2(OH)2.5(OCH2COONa)1/2]70。
The separation principle of the present invention is: Copper-lead mixed concentrate through inflation regrind after make sieve classification operation feeding granularity reach-
0.074mm grade is more than more than 70%, it is ensured that the monomer dissociation between each mineral, and achieves the selection of part galena
Property fine grinding purpose, then to material use high-frequency screen carry out classification, it is thus achieved that screening product (undersize material) be lead concentrate
A, then adds acid LR inhibitor and sizes mixing for on-the-sieve material, and this inhibitor is a kind of interworking mixed solution, in strong acid
Property, in ore pulp, it mutually firmly can cover at its table after absorption after preferentially surface to galena carries out pickling and between galena
Face, the carboxyl in LR has the strongest hydrophilic simultaneously, and between the hydrone in itself and ore pulp, mutually absorption forms hydrogen bond and forms
Closing, the chemical bond energy powerful by material itself makes galena hydrophilic and suppressed, and tennantite is owing to containing arsenic in crystal, its
Before pulp potential system does not occurs significantly to reverse, and can not associate between inhibitor, float under bubble,
Tennantite and galena is made to obtain high efficiency separation.
The invention has the beneficial effects as follows, the stable in properties of acid LR inhibitor, and the inflation used is regrinded sieve classification
Fast-flotation separating technology flow process is reasonable, and ore dressing is effective, with low cost, it is achieved that tennantite effectively divides with galena
From.
In a word, the present invention uses inflation sieve classification fast-flotation of regrinding to separate and acid LR inhibitor method, has preferably
Adaptability, it is achieved that the high efficiency separation of tennantite and galena, inflation regrinding process can preferably realize to tennantite with
The selective milling of galena, acid LR inhibitor can realize the Selective depression to galena in fast-flotation operation.
The present invention has good stability, strong adaptability, the feature of medicament high-efficiency environment friendly concurrently.
