Description
Technical field
The invention belongs to the biological metallurgy technical field, design also uses the novel ore deposit bio-reactor that soaks low to the leaching microbacteria degree of injury, that be easy to maximize to carry out the bio-oxidation of leaching microbacteria to sulfide mineral.
Background technology
Non-ferrous metal is requisite base mateiral of national economy, national defense industry and scientific technological advance and grand strategy goods and materials, is widely used in key areas such as Aeronautics and Astronautics, sophisticated weapons, information, traffic and the energy.Several major metal consumptions of China rank first in the world, and at full speed increase year by year.But owing to be subjected to the restriction of resource and production practice, Mineral Resources in China is exhausted day by day! Calculate according to verifying resource reserve and production practice at present, China's copper can only be again with 13 years, and plumbous 6.5 years, zinc 8.1 years, antimony 4.3 years, molybdenum 12.7, gold 8 years.
On the other hand, the Mineral Resources in China utilization ratio is low, is 1/4 to 1/7 of international most advanced level.Its major cause, the one, the characteristics of Mineral Resources in China are that easily to handle the ore deposit few, only account for 20%, 80%, poor, thin, assorted, refractory ore, difficulty of processing is big; The 2nd, the traditional technology that adopts can not effectively be utilized low-grade, refractory ore to the grade requirement height of ore at present, and the energy consumption height, and environmental pollution is serious.
Show that more than Mineral Resources in China processing and utilization present situation is unfavorable for the national economy sustainable development strategic objective.And the biological metallurgy technology is low to ingredient requirement, the metal content of ore＜0.1% is economically valuable still, can greatly enlarge the mineral resources scope, can solve an inadequate resource and a reluctant difficult problem to a great extent, for the sustainable development of national economy provides resource guarantee.
Nonferrous metals ore is the sulfide occurrence status more, the biological metallurgy technology mainly is to utilize iron, sulfur-oxidizing bacteria, carries out the leaching of nearly all sulphide oress such as copper, uranium, gold, manganese, lead, nickel, chromium, cobalt, bismuth, vanadium, cadmium, gallium, iron, arsenic, zinc, aluminium, silver, germanium, molybdenum, scandium.Arsenic-containing gold ore is a kind of typical ore type, and essential mineral is pyrite, mispickel, and gold becomes inferior microscopic morphology to be wrapped in the sulfide with particulate or infects in the lattice of pyrite, mispickel, fine grinding and the directly very difficult extraction of cyanide process.Use the integument of iron, sulfur-oxidizing bacteria exploded external, can make gold expose out, help chemistry and leach, improve the rate of recovery of gold.Arsenic generates the ferric arsenate compound at last, generates gas be recycled safety and environmental protection more than traditional sinter process." bacterium leaching-extraction-electrodeposition " technology of copper mine is easier, and can directly obtain high purity copper.The biological metallurgy technology is particularly suitable for that lean ore, abandoned mine, unbalanced-ore and difficulty are adopted, difficult choosing, difficult smelting ore deposit, and has outstanding advantages such as process is simple, cost is low, energy consumption is low, environmental pollution is little, is used widely in industrial production.
Biological metallurgy soaks with having, dump leaching and three kinds of modes of drill traverse.Ground soaks, the dump leaching cycle is long, and efficient is low; And the drill traverse cycle is short, efficient is high, is suitable for most precious metals.The employed reactor of drill traverse almost is to stir the slot type bio-reactor all at present.Stir not only complex structure of slot type bio-reactor, the energy consumption height more because violent stirring action causes ore in sand form that microbial cells is produced the intensive abrasive action, makes thalline death, soaks ore deposit efficient thereby influenced greatly.
In order to have overcome the above-mentioned defective that stirs the slot type bio-reactor, the present invention has designed novel multiple draft tubes compression ring bioreactor, and is applied to the biology leaching of sulfide mineral and the cultivation of ore-leaching bacteria.
Summary of the invention
The purpose of this invention is to provide a kind of microbial metallurgy drill traverse mode that is applicable to, low to the microbial cells degree of wear, what be easy to again maximize soaks the ore deposit bio-reactor, the cultivation that is used for bioleaching and soaks the ore deposit bacterium.
For reaching described purpose, the cultivation that the present invention adopts multiple draft tubes compression ring bioreactor to soak the ore deposit and soak the ore deposit bacterium.This reactor promotes power to alleviate ore in sand form and the paddle degree of wear to microbial cells with pressurized air as liquid, and the bio-oxidation for microorganism growth and mineral provides oxygen simultaneously; Inside reactor has a plurality of guide shells, helps the maximization (Fig. 1) of bio-reactor with the aspect ratio (H/D) that reduces reactor.
Below the present invention is described in detail:
The present invention is applicable to bioleaching that contains sulfur mineral breeze drill traverse mode or the cultivation of soaking the ore deposit bacterium.This reactor comprises four parts, is respectively tank body, jar end, guide shell and measurement and control device.
Tank body is cylindric, and irritating the body top is open design.The aspect ratio of tank body (H/D) can reach 1～1.5 scope, helps the maximization of bio-reactor.Mini-reactor (＜3m
3) tank body has chuck outward, large-scale reactor is then installed coil pipe in jar, feed cold or hot water is used for temperature of reactor control.
The sealing of the jar end can be adopted multiple shape, as forms such as flat, the oval end, tapered bottom, many tapered bottom., there are a plurality of inlet mouths at jar end, lay respectively at jar interior each guide shell under.A side is equipped with air nozzle or porous air sparger in the jar of inlet mouth, makes the air homodisperse in pot liquid that enters.Middle part, the jar end has drainage conduit to be used to react the discharge of feed liquid and the discharge of reactor washes.
Guide shell is positioned at the inside of cylindrical tank; The guide shell height is approximately 80% of cylindrical tank height, is lower than a jar interior liquid level, and the guide shell bottom is near the cylindrical tank bottom; The guide shell number is more than two, and optimal number is three; A plurality of guide shells are uniform distribution in cylindric tank body; Fix by mounting block between each guide shell and between guide shell and the tank body.
Reactor features is its structure and ratio, and reactor volume is changeable, and small-sized is several liters, and large-scale can reach several kilosteres.Reactor tank body aspect ratio (H/D) can reach 1～1.5 scope less than 3; The tank body cross-sectional area is 1.5～2 times of guide shell cross-sectional area sum; The aspect ratio of guide shell (h/d)＞3.
Reactor adopts acid resistance corrosive material to make, and mini-reactor can adopt plastics, glass or pmma material, and large-scale reactor can adopt stainless material, if be that material then need be coated with corrosion resistant coating in the surface with the ordinary steel.
Reactor has temperature, pH, dissolved oxygen, redox potential potential electrode.Mini-reactor (＜50L) electrode is installed in the top of jar, inserts liquid level; Large-scale reactor electrodes is installed in the mid-way of tank body.Temperature electrode links to each other the water temperature in controlling reactor chuck or the coil pipe with the outer demonstration of jar with control instruments; PH, redox potential electrode link to each other with data acquisition computer; Dissolved oxygen electrode links to each other with jar display instrument outward.
Reactor promotes power with pressurized air as liquid and promotes the material macroscopic view to mix and mass transfer process, because inlet mouth is positioned under the guide shell, air almost all enters guide shell, thereby the mean density that makes the guide shell inner fluid is significantly less than the mean density of guide shell outer fluid, and the existence of this pressure difference has produced the power that fluid circulates.Soaking the ore deposit bio-reactor with traditional stirring-type compares and has alleviated wearing and tearing and the destruction of ore in sand form to microbial cells greatly.
Reactor can adopt batchwise operation, feed supplement operation or operate continuously.Batchwise operation is a disposable adding material before the reaction, does not add material in the middle of the reaction, and reaction finishes the operating method of the disposable discharge material in back.Feed supplement operation is to add partial material before the reaction, adds material in the middle of the reaction but does not discharge material, and reaction finishes the operating method of the disposable discharge material in back.Operate continuously is to discharge material while adding material in the reaction process, and the influent volume equates with the expel liquid volume, the operating method that liquid volume remains unchanged in the reactor.
In the operate continuously mode, can adopt that a reactor uses separately, two or more reactors in series, the placed in-line multiple array mode in a plurality of reactor back in parallel earlier.For example, preceding two reactor parallel connections of five reactors, the array mode of back three reactors in series.
Reactor gas-liquid mass transfer and mixed performance are mainly investigated gas holdup, liquid mixing time, the volume oxygen mass transfer coefficient (K of single reactor batch operation mode
LA) with breeze deposition situation.
Gas holdup is that reactor contains the percentage ratio that gas volume accounts for cumulative volume in the liquid under aeration status.Adopt the gas holdup of bed expansion method assaying reaction device under the gas with various apparent speed, gas holdup reached 7.7% (accompanying drawing 3) when actual measurement gas superficial speed was 1.82cm/s.
The liquid mixing time is meant that liquid reaches the needed time when mixing in the reactor.Respectively adorn a pH electrode at a tank deck and a jar end during mensuration, add a certain amount of hydrochloric acid and timing at tank deck, the needed time is the liquid mixing time when tank deck shows that with a jar end pH electrode numerical value reaches 98% similarity.The liquid mixing time was 17s (accompanying drawing 4) when actual measurement gas superficial speed was 1.8cm/s.
Volume oxygen mass transfer coefficient (K
LA) be the amount of unit liquid volume dissolved oxygen in the unit time, unit is time/one.Employing nitrogen is driven the oxygen in the liquid during measurement, is 0 up to the dissolved oxygen electrode displayed value, closes nitrogen and bubbling air then, with dissolved oxygen electrode record dissolved oxygen upcurve, volume calculated oxygen mass transfer coefficient in view of the above.The volume oxygen mass transfer coefficient reached 18.5 * 10 when actual measurement gas superficial speed was 1.6cm/s
-3L/s (accompanying drawing 5).Vary in size or Billy's jar of difference slightly, under the same gas apparent speed, gas holdup, liquid mixing time, volume oxygen mass transfer coefficient (K
LA) have difference.
In order to observe the deposition situation of breeze in reactor, it is 180 purpose breezes that sieve is got granularity, places the system of sky G﹠W, observes the height of deposition of breeze at reactor bottom under different air flows.The result shows, has only the breeze deposition of a little, if strengthen air flow then depositional phenomenon obviously alleviate.Even a small amount of breeze deposition is arranged, settling also is to be in suspension and the sedimentary running balance, and settling internal oxidation speed and rate of mass transfer restriction are not serious.The sedimentation experiment explanation, reactor is suitable for the purpose of bioleaching fully.
When soaking the ore deposit, be that to be mixed with content be the feed liquid of 10%～25% breeze and add reactor for breeze water about 180～200 orders at first as required with granularity, regulate pH to required scope with sulfuric acid, regulate suitable temperature, air flow, pour the nutrient solution of the ore immersion bacterial culture that is in the growth index middle and later periods then in the pre-portion of reactor, the nutrient solution volume is equivalent to feed liquid total amount 10%.
Ore-leaching bacteria mainly comprises thiobacillus ferrooxidant (T.ferrooxidans), thiobacillus thiooxidans (T.thiooxidans), thermophilic thiobacillus (Thiobacillus caldus), leptospirillum ferriphilum (Leptsopirillumf ferrooxidans), has a liking for sour sulfolobus genus bacterium iron or sulfur-oxidizing bacterias such as (Sulfolobus), wherein some bacterium promptly can ferric oxide also can sulfur oxide, as thiobacillus ferrooxidant.The bacterial classification that uses in the production is the natural mixing ore immersion bacterial culture that comprises above-mentioned main ore immersion bacterial culture through domestication mostly.
Temperature of reactor is slightly different according to the difference of use bacterial classification, generally is controlled at about 37～42 ℃; If use high temperature resistant bacterium temperature then can be controlled at more than 42 ℃.Initial reaction stage reactor pH generally is controlled at below the pH4 with sulfuric acid, along with the pH that carries out that reacts is reduced to below the pH1 gradually.The reactor saturation dissolved oxygen generally is controlled at more than 10% or 30%.
For bioleaching, feed liquid is breeze and water, regulates below the pH4 with sulfuric acid, can not add other composition; For the cultivation of soaking the ore deposit bacterium, nutrient solution can use breeze and water, also can use the chemosynthesis substratum of principal component, as Starky substratum, 9K substratum.
This novel reactor is applied to the bio-oxidation dearsenification of high arsenic-containing gold concentrate, and arsenic-removing rate reaches more than 85%, and this novel reactor is applied to the cultivation of ore-leaching bacteria, and effect is better than shake-flask culture.
