Description
Technical field
A kind of Cyanide Leaching groove relates to the phase reaction equipment in a kind of hydrometallurgy process, especially for the leaching vat of gold Cyanide Leaching.
Background technology
It is main production gold method that Cyanide Leaching extracts gold from.Stirring cyanidation leaches and refers to levigate material and Cyanide Leaching agent are placed in the leaching steel basin, completes the process of leaching under the condition that stirs and inflate.
The electrochemical reaction that gold dissolves in the Cyanide Leaching steel basin is:
4Au+8CN
-+O
2+2H
2O=4Au(CN)
- 2+4OH
-
Prussiate and oxygen concentration are two topmost factors that determine golden dissolution rate.
At present, the Cyanide Leaching groove mainly is divided three classes: mechanical stirring Cyanide Leaching groove, pneumatic blending Cyanide Leaching groove, air and mechanically combining stirred leaching tank.China's gold mine Cyanide Leaching steel basin overwhelming majority used is the mechanical stirring leaching vat, this Cyanide Leaching steel basin is to transform a little to form on the basis of mining steel basin, mainly insert gas-filled valve or inflate by stirring in hollow axial groove at the periphery of flowsheet of slurry agitation groove, have the shortcomings such as energy consumption is high, easy deep gouge, air-dispersion is poor, dissolved oxygen amount is low, leaching efficiency is low, leaching cycle is long, the shortcoming of existing Cyanide Leaching steel basin has seriously restricted the production efficiency of gold mine.
Before 20 century 70s, China mainly adopts single impeller Cyanide Leaching steel basin.Along with developing rapidly of China's gold mine selecting and purchasing industry, the units such as the metallurgical design studies of China YouSe total institute have developed SJ type bilobed wheel Cyanide Leaching steel basin, and obtain widespread use.Its airing form mainly contains two kinds, and a kind of is quill shaft inflation (Fig. 1), and another kind is a steel pipe ring inflation (Fig. 2) that a lot of small sircle holes are arranged by the impeller below.No matter be quill shaft inflation or the inflation of bottom annulus, its shortcoming is mainly by the stirring action of impeller, airflow to be smashed to be small bubbles, bubble diameter is large, the air dispersion weak effect, dissolved oxygen content is low, and air utilization ratio is low, and most of air effusion ore pulp surface is returned in atmosphere, cause the gold cyanidation leaching rate slow, the Cyanide Leaching cycle is long.
Patent CN200720092935.2 changes the bottom inflation ring into the so-called microvesicle Inflatable dispenser (Fig. 3) that is formed and punched by up and down two block plates on the steel plate of upper strata, although can being distributed in groove even air, but the restriction that is subject to processing, bore dia on steel plate is still bigger than normal, cause bubble diameter bigger than normal, air utilization ratio is low; In addition, gold cyanidation leaches and all to carry out under alkaline environment, and on steel plate, the hole is easy to tie calcium and blocks.
Above-mentioned Cyanide Leaching steel basin is to transform a little to form on the basis of mining steel basin mostly, the shortcomings such as the ubiquity air dispersion is poor, air utilization ratio is low, dissolved oxygen amount is low, leaching efficiency is low, leaching cycle is long have seriously restricted the production efficiency of gold mine.

A kind of Cyanide Leaching groove of the present invention is characterized in that described injection aerator in leaching vat cell body bottom, and the part of aerator is inserted in the leaching vat cell body, and level was arranged in centripetal minute.
A kind of Cyanide Leaching groove of the present invention is characterized in that described injection aerator is 3～10.
A kind of Cyanide Leaching groove of the present invention is characterized in that described aerator nozzle diameter is 0.5mm～6.0mm.
A kind of Cyanide Leaching groove of the present invention is characterized in that described several spray aerators and connect with leaching vat cell body steam line outward respectively, and this steam line is around the annular steel pipe that is arranged on the outer bottom of leaching vat cell body.
A kind of Cyanide Leaching groove of the present invention is characterized in that described steam line connects with air compressor machine by controlling pipeline, is provided with reducing valve, under meter, tensimeter on the control pipeline.
A kind of Cyanide Leaching groove of the present invention, high-pressure air can be sprayed by aerator and enter in ore pulp, can form a large amount of small bubbles in ore pulp, improve the gas-to-liquid contact area, improve the dissolved oxygen content in ore pulp, improve the gold cyanidation leaching rate, shorten the gold cyanidation extraction time, simplify the Cyanide Leaching flow process.
