Abstract
The invention discloses a copper-nickel sulfide ore collecting agent, which consists of the following materials in parts by weight: 20-40 parts of allyl isobutyl thiocarbamate, 20-30 parts of methyl isobutyl carbinol, 10-30 parts of ammonium butyrate-blackcurrant, 10-20 parts of azothionitrile ester and 5-10 parts of blackcurrant acid, and the catalyst is prepared by fully mixing and uniformly stirring for 0.5-1 hour.
Description
Technical field
The present invention relates to non-ferrous metal industry for the floating agent of ore dressing, particularly a kind of copper nickel sulfide mineral collecting agent.
Background technology
Continuous exploitation for a long time, it is complicated that ore properties is tending towards, make the separation and Extraction difficulty of copper and nickel resources increasing, strengthened the difficulty of its comprehensive development and utilization processing, expose aborning fine fraction, particularly granularity reclaims scarce capacity, the features such as floatation process of serpentine severe jamming nickel mineral at the fine fraction mineral of-0.037mm.Serpentine is easy argillization in floatation process, serpentine sludge lotus positive electricity after argillization, interval at the alkalescent pH that nickel sulfide ore flotation is conventional, nickel sulfide ore bear electricity, therefore serpentine sludge is easily surperficial in fine fraction nickel sulfide ores by out-phase cohesion cover cap, affects fine fraction nickel sulfide ore floating, or enters concentrate with fine fraction nickel sulfide ore floating, cause fine fraction nickel sulfide ore to reclaim not exclusively, affect nickel metal recovery rate and concentrate grade.
Summary of the invention
The object of the invention is to avoid the deficiencies in the prior art that a kind of have collecting and foaming double attribute are provided, selectively good, collecting ability is strong, can improve flotation froth situation, strengthen secondary enrichment, improve the copper nickel sulfide mineral collecting agent of fine fraction Ni sulphide mine thing flotation effect.
For achieving the above object, the invention provides a kind of copper nickel sulfide mineral collecting agent, by the material of following weight portion, formed:
Allyl sulfide is for 20-40 parts of isobutyl carbamates
20-30 parts of methyl isobutyl carbinols
10-30 parts of butyl ammonium aerofloats
10-20 parts of sulphur nitrogen nitrile esters
5-10 parts of black powder acid.
In above-mentioned collector composition, allyl sulfide is 30 parts for preferred weight part of isobutyl carbamate, and preferred weight part of methyl isobutyl carbinol is 25 parts, and preferred weight part of butyl ammonium aerofloat is 20 parts, preferred weight part of sulphur nitrogen nitrile ester is 15 parts, and preferred weight part of black powder acid is 10 parts.
Described a kind of copper nickel sulfide mineral collecting agent, by following method, prepared:
At normal temperatures and pressures, allyl sulfide is added in stirred tank by required weight for isobutyl carbamate, methyl isobutyl carbinol, sulphur nitrogen nitrile ester, butyl ammonium aerofloat and black powder acid, under room temperature, be uniformly mixed 0.5～1 hour, make.
The weight portion scope of the combination of each component of the present invention and each component, determines by lot of experiments, and combinations thereof and weight portion scope can be given full play to the cooperative effect of each component.The present invention compared with prior art has the following advantages:
1. selectively good, collecting ability is strong, for mineral processing production, can obviously improve nickel ore concentrate grade and the rate of recovery, is applicable to the ore-dressing technique of lean ore, difficult ore dressing.
2. can improve flotation froth situation, strengthen secondary enrichment, improve fine fraction Ni sulphide mine thing flotation effect.
The specific embodiment
In following examples, enumerated the situation of the weight portion variation of three kinds of raw materials, the method for preparing described collecting agent is constant.But should be noted that: the proportioning of each component of collecting agent should be adjustable in scope by weight percentage, allyl sulfide is for 20-40 parts of isobutyl carbamates specifically, 20-30 parts of methyl isobutyl carbinols, 10-30 parts of butyl ammonium aerofloats, 10-20 parts of sulphur nitrogen nitrile esters, 5-10 parts of black powder acid, the preparation example of other proportionings repeats no more.
In order to describe more intuitively different embodiment Raw weight portions, change the impact on mineral processing index, select under the same conditions single Copper Ores to carry out beneficiation test, list respectively grade and the rate of recovery of copper, nickel rough concentrate, by the performance of the synthetic collecting agent of the variation reflection different material weight portion of copper, nickel rough concentrate mineral processing index.Copper, nickel rough concentrate are of high grade, illustrate that the selectivity of collecting agent is strong; The rate of recovery of copper, nickel rough concentrate is high, illustrates that described collecting agent collecting performance is strong.
In three embodiment of the present invention, the preparation method of copper nickel sulfide mineral collecting agent is, at normal temperatures and pressures, allyl sulfide is sour for isobutyl carbamate, methyl isobutyl carbinol, sulphur nitrogen nitrile ester, butyl ammonium aerofloat and black powder, by the weight of appointment in table 1, add in stirred tank, under room temperature, be uniformly mixed 30 minutes, 45 minutes, 50 minutes or 1 hour, make.Then with this collecting agent, copper nickel is carried out to beneficiation test.
Comparative example 1 collecting agent used is PN-405, and comparative example 2 collecting agent used is Z200, and copper nickel is contrasted to beneficiation test.
Embodiment and comparative example beneficiation test raw ore copper grade 0.95% used, nickel grade is 1.35%, and ore part of nickel mineral disseminated grain size is thinner, and the fine fraction nickel sulfide ore of-0.037mm accounts for 9% left and right of total nickel minerals.
The concrete numerical value of embodiment and comparative example is in Table 1.
After beneficiation test finishes, the concentrate product of respectively beneficiation test being obtained carries out granularity Detection, investigates the effect situation of collecting agent to thing under different grain size.Embodiment of the present invention concentrate product granularity testing result is in Table 2, and comparative example concentrate product granularity testing result is in Table 3.
In upper table, data are embodiment concentrate product essential mineral particle size average.
In upper table, data are comparative example concentrate product essential mineral particle size average.
From product granularity testing result, can find out, in embodiment concentrate, within the scope of 0.0371mm-0.0185mm, pentlandite distributive law increases, illustrate that collecting agent can effectively reclaim fine fraction nickel sulfide ore in ore, improve nickel recovery, gangue size distribution remains unchanged substantially simultaneously, fine fraction serpentine sludge does not float with fine fraction nickel sulfide ore, illustrates that collecting agent has good selectivity, when improving nickel recovery, can guarantee nickel ore concentrate in MgO content do not exceed standard.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
