Description
Technical field
The present invention relates to gold smelting equipment technical field, more particularly to a kind of rectangular leaching tanks.
Background technology
China accounts for the half of the country of gold industry production using the method that refined gold ore cyaniding extraction of gold process directly produces gold.
The leaching of gold is the important link of extraction of gold by cyanidation technical process.Dissolving of the gold in cyanide solution is electrochemical dissolution, when
When the gold of solid state is immersed in cyanide solution, under the action of oxygen and CN- in the solution, the surface of the gold of solid state
It soon reacts, gold becomes complex ion Au (CN) 2- and dissolves, and is formed about saturated solution on the surface of gold；In order to
Gold and silver is set to obtain faster solution rate, rational condition is neither singly the concentration of dissolved oxygen, is not also singly free cyanide
Concentration, but the ratio of the two concentration.The concentration of free cyanide is ignored if only putting undue emphasis on inflation, or is added
Excessive cyanide, the leaching velocity to improving gold and silver are all that effect is little, and can cause inflation power or cyanide
Waste.Therefore, in order to improve the economic and technical norms of cyanide plant, using rational extract technology and equipment, rational leaching is selected
Go out condition, grasps rational operating method and become the important topic produced for cyaniding.
In recent years, many researchs and improvement were done on leaching process both at home and abroad, and was concentrated mainly on and improves mechanical agitation effect
In terms of rate and raising oxygen utilization rate, such as means of oxygen rich leaching, pressure leaching, magnetic vibrations pretreatment leaching, multilayer leaching, improve
Leach groove height and diameter proportion etc..Should say it is single just in a certain respect, these measures can obtain certain effect, but most feelings
Under condition, comprehensive cost performance, effect is not obvious or improves less, and not substantive change, some transformations but bring other sides
The side effect in face, such as maintenance load it is big, to power reguirements harshness unfavorable factor.Stirring and inflation side of the country in stirred tank
Successively there are multiple significant improvement and raising in face, that is, uses the inflation of single layer mechanical agitation to leach, the double-deck mechanical agitation inflation is leached, nothing
Stir efficient foam Oxidation Leaching, Tiny pore injection is leached, disc type air shears leaching etc..With these advanced technologies
Using all bringing the raising of different degrees of technical indicator and benefit each time.But these leaching tanks common drawbacks are all desirable
Mechanical agitation, energy consumption is big, and air utilization ratio is low, and operating environment is poor.
The cylindrical groove bodies of all producers application at present, it is more difficult that cylindrical groove body processing is processed compared to rectangular groove body, investment compared with
Greatly.Connection between cylindrical groove body needs to realize by pipeline, increases construction cost, and pipeline is easy to block.
Invention content
It is an object of the invention to be to provide a kind of rectangular leaching tanks, which is made using the pressure of compressed air
For improving the uniformity of flowsheet of slurry agitation and the utilization rate of air, ore pulp is set to be come into full contact with cyanide, leaching effect becomes apparent from.
In order to solve the above technical problems, the present invention provides a kind of rectangular leaching tanks, including shell, the shell be equipped with into
Mine mouth, is equipped with several rectangular groove bodies arranged in arrays in the shell, and each rectangular groove body is equipped with manhole, and adjacent two
It is separated by partition between the rectangular groove body, notch is equipped at the top of the partition board；It is uniformly provided in the square groove body several
Riser, the promotion bottom of the tube are equipped with gas generator, and the gas generator bottom is fixed on described rectangular by supporting leg
Groove body bottom；The outside of each riser is equipped with a ventilation duct, and several ventilation ducts are all connected with same total in inlet
The outlet of air hose, the ventilation duct is set in the gas generator.
Optionally, using far from the iron ore feeding hole, as direction, the bottom edge height of the notch continuously decreases.
Optionally, adjacent two notch bottom edge differences in height are 10cm.
Optionally, the outlet is laterally set in the gas generator.
Optionally, the gas generator is round platform tubular, and the lower end bore of the gas generator is more than upper end bore.
Optionally, the ventilation duct is connect with the blast main by hose.
Optionally, the inlet of the ventilation duct is equipped with hand-operated valve, motor-driven valve and electromagnetic flowmeter.
Optionally, each rectangular one jiao of groove body top is equipped with an access hole, and the access hole is set to the riser
Surface.
Compared with prior art, the beneficial effects of the present invention are：The rectangular leaching tanks of the present invention are by multiple square grooves
What body was constituted, and separated by partition board jaggy between adjacent two rectangular groove body so that the ore pulp energy in adjacent prismatic groove body
Another rectangular groove body is enough entered by notch, without being transmitted by pipeline, avoids line clogging.Moreover, the ventilation of the present invention
On the one hand pipe expands the inner space of riser, improves riser single lift ore pulp amount, add set on the outside of riser
Fast stirring efficiency.And since ventilation duct is set to outside riser, the ore pulp in riser avoids contacting with ventilation duct, eliminates
The frictional force of ore pulp and ventilation duct, also accelerates promotion rate, has further speeded up stirring efficiency.On the other hand, ventilation duct
Outlet be set to gas generator inside, change the direction that original air is blown out downwards, air made to blow to gas generator
Side wall promotion of the ore pulp in riser is also accelerated due to the collective effect of the compressing force of the blowing force and air of air
Rate accelerates stirring efficiency again.With greatly improving for stir speed (S.S.), ore pulp and the contact of air and cyanide are also
More fully.Furthermore stirring is faster, the mutual collision of the solid particle in ore pulp and also fiercer, the particle surface that rubs
Film be easier to be destroyed, make that particle contacts with cyanide more fully, be also achieved that better leaching effect, improve
Leaching efficiency.In addition, coming into full contact with for ore pulp and air and cyanide, also can fully utilize cyanide, reduce cyanogen
The usage amount of compound reduces the dosage cost of cyanide, saves production cost.
The agitating mode of air compression is used to reduce machinery without any mechanical agitation structure and stir completely in the present invention
The energy consumption mixed avoids the repair to mechanical structure, also just reduces the cost of plant maintenance, and the cost of labor safeguarded.And
And no mechanical agitation, also eliminate the need for the noise of mechanical agitation generation.
