Description
Technical field
The present invention relates to a kind of complex copper sulphide ore mineral processing index technology that is used for effectively improving.
Background technology
Electrochemical regulating and controlling can make the floatation process selectivity significantly improve, and is applicable to the separating flotation of polymetallic ore and bulk concentrate.The good combination of electrochemistry and novel and effective floating agent is the new way that solves the complicated sulfuration mine FLOTATION SEPARATION.The separation of plumbous zinc mineral is brought into play enormous function substantially through having solved the control of pulp potential in industrial production; And copper sulfide ore is owing to exist copper mineral many than the lead minerals kind, and the best flotation current potential of each copper mineral is all different, copper sulfide electric potential regulating in the past can only be controlled the best flotation current potential of a kind of main copper mineral, the unmanageable problem in aspects such as automatic control that exists pulp potential and chemical agent to add is also seldom in industrial application.In order to solve this difficult problem, be badly in need of seeking the short-cut method of copper mine electric potential regulating.
Summary of the invention
The purpose of this invention is to provide a kind of copper-sulphide ores technique of preparing efficiently, can significantly improve copper mineral metal ore dressing recovery index.
A further object of the present invention provides a kind of copper-sulphide ores floating agent system and implementation method, when improving the copper mineral metal recovery rate, reduces dosing, reduces production costs and alleviates environmental protection pressure.
A further object of the present invention provides a kind of flotation flowsheet and configuration of easy to operate, designs simplification, saves investment and cuts down the consumption of energy.
The technical solution adopted for the present invention to solve the technical problems is: for achieving the above object, the present invention takes following technical scheme: a kind of technology that improves complex vulcanizing copper mine ore floatation indicators, increase an air-breathing agitator between the tank diameter of this technology before grader and flotation newly, in this air-breathing agitator, utilize air to adjust the copper-sulphide ores pulp potential by the control mixing time; Adopt isoamyl xanthate and medicament sulphur nitrogen eyeball ester as copper mineral selective copper collector foaming agent; Carry out the preferential fast-flotation of copper mineral, may further comprise the steps:
A, floating agent prescription are formed
The copper flotation operation utilizes air to adjust the copper-sulphide ores pulp potential in 10-30 minute by the control mixing time in air-breathing agitator with lime control grinding flotation pH values of pulp 7.5～14, keeps pulp potential more than or equal to 100mV calomel reference electrode current potential; Isoamyl xanthate 10～20g/t; Sulphur nitrogen eyeball ester is as collecting agent foaming agent 30～40g/t;
B, medicament add place and mode
Lime and isoamyl xanthate make an addition in the ball mill, and sulphur nitrogen eyeball ester makes an addition in the preceding tank diameter of flotation;
C, flotation process
Only one roughing once purging selection one obtains copper concentrate to recleaning.
Described a kind of technology that improves complex vulcanizing copper mine ore floatation indicators, lime and isoamyl xanthate make an addition in the ball mill, after ore pulp enters in the air-breathing agitator, utilize air to adjust the copper-sulphide ores pulp potential by the control mixing time, under the effect of the aerial oxidant oxygen of current potential, pulp potential from grinding process-300mV is progressively to 100mV, controlling current potential at last just can more than or equal to 100mV, in this process, the best current potential of the copper-sulphide ores of all kinds is all in this interval, when various copper-sulphide ores reach best current potential, a spot of isoamyl xanthate just carries out the optimization mineralising with it, add sulphur nitrogen eyeball ester collecting agent and foaming agent as a supplement in the tank diameter before entering flotation, thereby accelerated copper flotation speed, when copper is roughly selected, scrape fast.
Described a kind of technology that improves complex vulcanizing copper mine ore floatation indicators, lime are adjusted the PH scope 7.5～12, isoamyl xanthate 10～20g/t, and sulphur nitrogen eyeball ester is as collecting agent foaming agent 30～40g/t.
Advantage of the present invention is:
The technological process of copper-sulphide ores flotation new technology of the present invention is consistent with the all-round excellent first flotation flowsheet of tradition, it still is the all-round excellent first flotation of copper mineral, the different air control mixings time of just utilizing adjust copper-sulphide ores pulp potential flotation technology, the various key elements that comprise traditional floating operation factor by adjusting, reach raising and improve copper mineral flotation index and effect, make the complicated sulfuration mine thing obtain quick highly selective FLOTATION SEPARATION.It has two main points: the one, and main adjusting and control comprise traditional floating operation parameter of slurry pH, collecting agent kind, consumption and usage, flotation time and flotation flowsheet structure etc., the 2nd, do not adopt additional electrodes, do not use and add chemical reagent, only use airborne carrier of oxygen to adjust the copper-sulphide ores pulp potential by the control mixing time as the oxidation medicament.Compare with traditional floatation process, flotation technology of the present invention can (1) improve sorting index, and the metal recovery rate of general copper mineral on average improves 5～40 percentage points, and concentrate grade is higher simultaneously; (2) simplify flowage structure, flotation time only needs 2/3 of conventional flotation time, can save equipment investment and cuts down the consumption of energy.Technology of the present invention is to separate with medicament effect and then generation fast-flotation under the best potential state of each copper mineral, potential control method more in the past the copper potential control method easy, stablize, make flow process to shorten dramatically, scan number of times and can reduce to once and even do not scan, totally can reduce volume of equipment and reach 1/3rd; (3) reduce reagent consumption, reduce production costs.The copper collecting agent can reduce about 3/4ths to 2/3rds; (4) production operation is stable, and in PH=7.5～14 scopes, little to the flotation influence of copper mineral, the variation of ore character is little to sorting influence.
Adopt technology of the present invention and traditional flotation technology technology under equal conditions to handle copper sulfide ore, at aspects such as copper mineral flotation index, reagent consumption, flowage structure and energy consumptions, the technology of the present invention technology all has significant advantage, and economic benefit and social benefit are fairly obvious.
