Description
Technical field
The utility model relates to the golden agitator of a kind of ultrasound-enhanced leaching, belongs to technical field of wet metallurgy.
Background technology
Gold have also been obtained widespread use, as technical fields such as electronics, communication, aerospace, chemical industry, medical treatment due to its excellent performance in modern high technology industry.Along with the continuous increase of gold mine mining mineral resource amount, the reserves that higher-grade easily processes gold mine are day by day exhausted, and Refractory Au-ores will become the valuable source of gold industry from now on.How effectively and the exploitation Refractory Au-ores of persistence, be China's gold industry technical barrier in the urgent need to address.
Verified in gold geology reserves in China, about had about 1000t to belong to pyrite/arsenopyrite coated Refractory Au-ores, it is one of main Refractory Au-ores.The embedding cloth of gold in this kind of gold mine among pyrite and mispickel lattice, and wherein the sulphur of high-content and arsenic very harmful to Cyanide Leaching; Industrially must carry out pre-treatment to it, open the parcel to gold, remove the material that sulphur and arsenic etc. affect cyaniding simultaneously, can effective Leaching of Gold.At present, the industrial method for pre-oxidizing applied has: roasting method, high-pressure oxidation method, biological pre-oxidation method, oxidation method etc., but these methods all exist certain deficiency.Such as, roasting method easily causes burning, forms caking, hinders gold to leach further, and along with the raising of environmental requirement, waste gas pollution control and treatment cost improves, and its range of application is restricted; High-pressure oxidation method operates at high temperature under high pressure, and equipment material requires high, and investment cost is large, and undesirable to the material treatment effect higher containing organic carbon; The available bacterial classification of bacterial oxidation method is limited, and reaction time is long, ensure that bacteria live and breeding make reaction conditions comparatively harsh.Recent decades, along with the continuous research of scientific worker, successively there is Nitric acid catalyzing and oxidizing method, chlorination process and adopted the chemical substances such as superoxide, permanganate, potassium bichromate, perchlorate, hypochlorite, ozone to carry out the method for preoxidation in oxidation treatment process, but these methods, due to problems such as equipment, operation or costs, rest on the laboratory study stage substantially.
Although under the long-term endeavour of investigators, cyanide gold-leaching technology is own through obtaining significant progress.Along with peroxide reagent helps the appearance of leaching technology, the development of technology for gold extraction has been pushed to a climax.Under the effect of peroxide reagent that hydrogen peroxide is representative, the leaching rate of gold and even leaching yield are obtained for and significantly improve, and the leaching gold time significantly shortens.But, continue development on this basis and just seem more difficult.Soak golden speed to seem to reach certain limit, be difficult to substantial further raising.Therefore, technology for gold extraction development reach this climax stage while, enter again " bottleneck " stage.In this case, continue to improve the golden speed of leaching, need a kind of new breakthrough, and the fundamental way realizing new breakthrough be exactly seek new thinking from the intrinsic propesties of the golden process of leaching.Therefore, how intense cyaniding gold extraction technology, enhances productivity, thus reaches the reduction scale of capital construction, investment reduction, reduction production cost, has become key subjects of current gold scientific effort.
Summary of the invention
For above-mentioned prior art Problems existing and deficiency, the utility model provides a kind of ultrasound-enhanced leaching golden agitator.The golden agitator transmission shaft of this ultrasound-enhanced leaching and paddle wheel depart from cell body center, effectively prevent phenomenon of turning round and round, and be conducive to the Homogeneous phase mixing of solid-liquid-gas three-phase, improve rate of mass transfer, the utility model is achieved through the following technical solutions.
The golden agitator of a kind of ultrasound-enhanced leaching, comprise cell body 9, opening for feed 11, discharge port 12, whipped-up structure, ultrasound structure and ventilation device, described whipped-up structure comprises paddle wheel 1, transmission shaft 3 and electric motor 4, ultrasound structure comprises ultrasonic transducer 2, wire 6, ultrasonic generator 7 and turner 8, ventilation device comprises ventage 5 and air outlet 10, described cell body 9 departs from cell body center and arranges the transmission shaft 3 passed from cell body 9 top, transmission shaft 3 bottom is provided with paddle wheel 1, transmission shaft 3 upper end connects electric motor 4, transmission shaft 3 is installed the ultrasonic transducer 2 in hollow cylindrical, ultrasonic transducer 2 is connected with ultrasonic generator 7 by wire 6, wire 6 is provided with turner 8 and this turner 8 is connected with transmission shaft 3 top, transmission shaft 3 is provided with ventage 5 for hollow shape top end face, transmission shaft 3 is provided with air outlet 10 for hollow shape bottom end face.
End face side, described cell body 9 top is provided with opening for feed 11, and bottom cell body 9, side is provided with discharge port 12.
The using method of the golden agitator of this ultrasound-enhanced leaching: when connecting electric motor 4, electric motor 4 drives paddle wheel 1 rotation at a high speed along clockwise direction by transmission shaft 3.Ventilate to the ventage 5 on transmission shaft 3 top, gas is gone out by the air outlet 10 bottom transmission shaft 3 simultaneously, and the ore pulp in agitator can form airwater mist cooling admixture under the state stirred; Ore pulp in stirrer, under the air passed into and the strong stirring action of impeller 1, forms powerful eddy current rotary motion.Because transmission shaft 3 departs from cell body center, effectively prevent phenomenon of turning round and round, be conducive to airwater mist cooling mixing, make the increase of diffusion like this, accelerate the golden speed of leaching to a certain extent, meanwhile, the electric power that ultrasonic generator 7 produces is transferred to ultrasonic transducer 2 by wire 6, then electric energy conversion is that acoustic energy launches ultrasonic wave to the ore pulp in agitator 9 by ultrasonic transducer 2, and ultrasonic wave produces cavitation phenomenon in ore pulp.When cavitation bubble collapses, in space minimum in very short time and around cavitation bubble, produce the high temperature and about 5 × 10 of more than 5000K
7the high pressure of Pa, rate of temperature change is up to 10
9k/s, and the jet producing that strong shockwave and (or) speed per hour reach 400Km, the strong impact force formed under cavitation and acoustic pressure effect due to ore pulp and jet impulse goldc grains, therefore goldc grains surface is difficult to form passivation layer.Jet produces strong stirring action to ore pulp again, accelerates and facilitate the dissolving of goldc grains.To the continuous and effective leaching oxygen that ore pulp solution passes into air and both leaching process can be provided to need and also ensure that ultrasonic cavitation.In sum, due to paddle wheel 1 and pass into the violent stirring effect of air and hyperacoustic cavatition, largely solving the problem producing passivation layer when soaking gold, achieving the leaching velocity accelerating gold, improve the leaching yield of gold, shorten the object of extraction time.
The beneficial effects of the utility model are: transmission shaft and the paddle wheel of (1) this agitator depart from cell body center, effectively prevent phenomenon of turning round and round, and are conducive to the Homogeneous phase mixing of solid-liquid-gas three-phase, improve rate of mass transfer; (2) transmission shaft of this agitator is designed to hollow, and there is ventpipe on top, and there is escape pipe lower end, and ventilation effect directly occurs in transmission shaft, accelerates the gas stirring effect of ore pulp, has saved the device space simultaneously; (3) this agitator ultrasonic transducer is hollow cylindrical, can directly be enclosed within transmission shaft, can increase according to required ultrasonic power or reduce ultrasonic transducer quantity, ultrasonic transducer dismounting, easy for installation; (4) this agitator means structure is simple, stable.
