Description
Technical field
The present invention relates to gold smelting equipment technical field, particularly to a kind of square leaching tanks.
Background technology
China adopts the method that refined gold ore cyaniding extraction of gold process is directly produced gold to account for the half of the country that gold industry produces.The leaching of gold is the important step of extraction of gold by cyanidation technical process.Gold dissolving in cyanide solution is electrochemical dissolution, when the gold of solid state immerses in cyanide solution, under oxygen in the solution and the effect of CN-, the surface of the gold of solid state soon reacts, gold becomes complex ion Au (CN) 2-and dissolves, and at the near surface formation saturated solution of gold；In order to make gold silver obtain dissolution velocity faster, rational condition is singly neither the concentration of dissolved oxygen, is not also singly the concentration of free cyanide, but the ratio of both concentration.Ignoring the concentration of free cyanide if simply putting undue emphasis on inflation, or add excessive cyanide, the leaching velocity to raising gold silver is all that effect is little, and can cause the waste of inflation power or cyanide.Therefore, in order to improve the economic and technical norms of cyanide plant, adopting rational extract technology and equipment, select rational leaching condition, grasping rational operational approach just becomes the important topic that cyaniding produces.
In recent years, in leaching operation, did a lot of research both at home and abroad and improved, it is concentrated mainly on raising mechanical agitation efficiency and improves oxygen utilization rate aspect, such as means of oxygen rich leaching, pressure leaching, magnetic vibrations pretreatment leaching, multilamellar leaching, improving leaching tanks height and diameter proportion etc..List should be said just in a certain respect, these measures can obtain certain effect, but in most cases, comprehensive cost performance, effect is also inconspicuous or progressive little, not having substantial change, some transformation but brings the side effect of other side, as big in maintenance load, to unfavorable factors such as power reguirements are harsh.In the domestic stirring at agitator tank and inflation, priority has repeatedly significant improvement and raising, and namely the inflation of employing monolayer mechanical agitation is leached, bilayer mechanical agitation inflates leaching, spray leaching, the shearing leaching of disc type air etc. without stirring efficient foam Oxidation Leaching, Tiny pore.Along with the application of these advanced technologies, all bring the raising of technical specification in various degree and benefit each time.But these leaching tanks common drawback are all need mechanical agitation, power consumption is big, and air utilization ratio is low, and operating environment is poor.
The cylindrical cell body of current all producers application, it is more difficult that the processing of square cell body is compared in cylindrical cell body processing, invests bigger.Connection between cylindrical cell body requires over pipeline and realizes, and adds construction cost, and pipeline easily blocks.
Summary of the invention
It is an object of the invention to be to provide a kind of square leaching tanks, these square leaching tanks utilize the utilization rate of compressed-air actuated pressure effect uniformity and air to improve flowsheet of slurry agitation, make ore pulp and cyanide be fully contacted, and leaching effect becomes apparent from.
For solving above-mentioned technical problem, the invention provides a kind of square leaching tanks, including housing, described housing is provided with iron ore feeding hole, some square cell bodies arranged in arrays it are provided with in described housing, each described square cell body is provided with manhole, is separated by dividing plate described in adjacent two between square cell body, and described dividing plate top is provided with breach；It is uniformly provided with some risers in described square groove body, bottom described riser, is provided with gas generator, be fixed on bottom described square cell body by supporting leg bottom described gas generator；The outside of each described riser is provided with a ventilation duct, and some described ventilation ducts are all connected with same blast main in porch, and the outlet of described ventilation duct is located in described gas generator.
Optionally, with away from described iron ore feeding hole for direction, the base height of described breach is gradually lowered.
