Description
Technical field
The present invention relates to a kind of efficient chemical combination leaching device of environmental type copper mine.
Background technology
It is that, in the form of copper sulfide, copper sulfide is molten in the ammonia of suitable concentration that copper mine in nature has quite a few
In liquid, there are enough air to blast（Mainly oxygen participates in reaction）, copper-amine complex can be formed and dissolved, complete chemical combination simultaneously
Leaching after dissolving, then carry out solid-liquid separation to carry out next step operation.
Therefore, the chemical combination leaching device of copper mine is the requisite key equipment of process for copper processed, but existing copper mine chemical combination
There are two big defects in leaching device, so as to constrain the development of copper technology processed.One insufficient and inconvenient, the air that is that air is blasted
（Oxygen）Mix insufficient contact with ore pulp, leaching agent, the chemical combination leaching velocity of copper sulfide is slow, efficiency is low, need to increase special
Air blast equipment, increase equipment investment, also cause unnecessary trouble；Two is that ammonia is easily leaked, as ammonia is with height
Zest, volatile toxic and harmful, thus effect on environment is very big, also very big to the loss of ammonia, but if using close
Hull closure is reacted, and not only cost of investment is high, is also easy to cause the security incidents such as blast.
Therefore, if can design a kind of air it is automatically convenient blast, ammonia is not easy leakage, and be not the copper mine of pressure vessel
Efficient chemical combination leaching device, then with important actual application value.
The content of the invention
The technical problem to be solved in the present invention is exactly to overcome the deficiencies in the prior art, there is provided a kind of simple and practical, empty
Gas is automatically convenient to be blasted, ammonia is not easy leakage, and be not the efficient chemical combination leaching device of environmental type copper mine of pressure vessel.
To overcome the deficiencies in the prior art, the present invention to take technical scheme below：
A kind of efficient chemical combination leaching device of environmental type copper mine, including chemical combination leaching barrel and exhaust purifier, its feature
It is：The intervalve of chemical combination leaching barrel and exhaust purifier is detachably connected by flange, exhaust purifier by overflow pipe and
