Abstract
A kind of device of intense cyaniding Leaching of Gold, comprise the leaching vat group be made up of at least one leaching vat and the sodium cyanide storage tank be connected with this leaching vat group and oxygen storage tank, described each leaching vat are respectively arranged with opening for feed and discharge port, and the height of described each leaching vat is all greater than 10 meters.The utility model increases the structure of leaching vat height owing to have employed, oxygen pressure in ore pulp is improved at the pressure that bottom land produces by increasing ore pulp, realize the increase of oxygen concn, thus be conducive to improving gold leaching rate and accelerating leaching velocity, the utility model is connected to form continuously dynamic leaching by multiple leaching vat simultaneously, simple to operate, leaching efficiency is high, and equipment of the present utility model is simple, facility investment is few, considerably reduces the wasting of resources, and whole system is for opening wide system, realize running in open environment, be conducive to intense cyaniding Leaching of Gold.
Description
Technical field
The utility model relates to a kind of device of intense cyaniding Leaching of Gold.
Background technology
Gold is because of himself excellent stability, and ductility, good electrical and thermal conductivity, obtains flourish in the high-tech area such as supercomputer, aerospace.At present, cyanide gold-leaching technique is the most effective means of process gold mine.The Cyanide Leaching of gold is generally in the presence of oxygen, and make the gold in gold mine be dissolved in cyanide solution, its chemical equation is:
4Au + 8CN
-+ O
2+ 2H
2O = 4Au(CN)
2 -+ 4OH
-
As can be seen from above-mentioned chemical equation, for improving leaching velocity, the leaching yield of gold, can start with from two aspects: 1, improve concentration of cyanide; 2, oxygen concn in ore pulp is improved.But in actual production, improve concentration of cyanide reach the leaching velocity, the leaching yield that improve gold to be not only uneconomical, but also other base metal can be dissolved, put forward golden process make troubles to follow-up; Simultaneously due to prussiate severe toxicity, prussiate consumption is excessive, and subsequent disposal bothers.Therefore, people put into how to increase oxygen concn aspect extensive work.The device of more existing Cyanide Leaching gold adopts pressure-resistant seal equipment to improve oxygen concn, causes facility investment large, difficult in maintenance, can not increase oxygen concn well to improve gold leaching rate and to accelerate leaching velocity.
Summary of the invention
The purpose of this utility model is for above-mentioned existing problems and deficiency, there is provided a kind of to run in open environment, and equipment is simple, facility investment is little, can realize oxygen concn increase well to improve the device of the intense cyaniding Leaching of Gold of gold leaching rate and quickening leaching velocity.
The technical solution of the utility model is achieved in that
The device of intense cyaniding Leaching of Gold described in the utility model, be characterized in comprising the leaching vat group be made up of at least one leaching vat and the sodium cyanide storage tank be connected with this leaching vat group and oxygen storage tank, described each leaching vat are respectively arranged with opening for feed and discharge port, and the height of described each leaching vat is all greater than 10 meters.
Wherein, the bottom land of above-mentioned each leaching vat is respectively arranged with oxygen hose, and above-mentioned oxygen storage tank is connected with described oxygen hose by pipeline, described pipeline is provided with under meter and valve.
Above-mentioned sodium cyanide storage tank is connected with the leaching vat being positioned at the first step in each leaching vat by pipeline, and described pipeline is provided with control valve.
Conveniently and effectively realizing to enable the utility model leaching continuously, there is certain difference of altitude between above-mentioned each leaching vat, being convenient to ore pulp flow to next stage leaching vat from the leaching vat of upper level.
In order to make leaching effect of the present utility model better, in above-mentioned each leaching vat, be respectively arranged with mechanical stirring device.
The utility model increases the structure of leaching vat height owing to have employed, oxygen pressure in ore pulp is improved at the pressure that bottom land produces by increasing ore pulp, realize the increase of oxygen concn, thus be conducive to improving gold leaching rate and accelerating leaching velocity, the utility model is connected to form continuously dynamic leaching by multiple leaching vat simultaneously, simple to operate, leaching efficiency is high, and equipment of the present utility model is simple, facility investment is few, considerably reduces the wasting of resources, and whole system is for opening wide system, realize running in open environment, be conducive to intense cyaniding Leaching of Gold.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the device of intense cyaniding Leaching of Gold described in the utility model, comprise the leaching vat group be made up of 1 ~ 10 leaching vat 3 and the sodium cyanide storage tank 1 be connected with this leaching vat group and oxygen storage tank 7, be connected respectively by pipeline between adjacent two leaching vat of described each leaching vat 3, and described each leaching vat 3 are respectively arranged with opening for feed 2 and discharge port 9, and the height of described each leaching vat 3 is all greater than 10 meters, and the bottom land of described each leaching vat 3 is respectively arranged with 2 ~ 10 oxygen hoses 4, described oxygen storage tank 7 is connected with described oxygen hose 4 by pipeline, described pipeline is provided with under meter 5 and valve 6.When leaching vat 3 are only provided with one, described sodium cyanide storage tank 1 is connected with these leaching vat 3 by pipeline, described pipeline is provided with control valve 10; When leaching vat 3 are provided with at least two, ore pulp can be streamed to the leaching vat of last step by the leaching vat of the first step, and described sodium cyanide storage tank 1 is connected with the leaching vat 3 of the first step by pipeline, described pipeline is provided with control valve 10.Conveniently and effectively realizing to enable the utility model leaching continuously, there is certain difference of altitude between described each leaching vat 3, being convenient to ore pulp flow to next stage leaching vat from the leaching vat of upper level.In order to make leaching effect of the present utility model better, in described each leaching vat 3, be respectively arranged with mechanical stirring device 8.
The utility model is described by embodiment, but the utility model is not construed as limiting, with reference to description of the present utility model, other changes of the disclosed embodiments, as the professional person for this area easily expects, such change should belong within the scope of the utility model claim restriction.
