Description
Technical field
The present invention relates to a kind of efficient chemical combination leaching device of ammonia No leakage formula copper mine.
Background technology
Copper mine in nature is that in the form of copper sulfide, copper sulfide is molten in the ammonia of suitable concentration with the presence of quite a few
In liquid, there are enough air to blast（Mainly oxygen participates in reaction）, copper-amine complex can be formed and dissolved, chemical combination is completed simultaneously
Next step process can be carried out by leaching after dissolving, then carrying out separation of solid and liquid.
Therefore, the chemical combination leaching device of copper mine is the essential 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 is that air blasts insufficient and inconvenience, air
（Oxygen）Mix insufficient contact with ore pulp, leaching agent, the chemical combination leaching velocity of copper sulfide is slow, efficiency is low, it is necessary to which it is special to increase
Air blast equipment, increase equipment investment, also cause unnecessary trouble；Two be that ammonia is easily leaked, because ammonia is that have height
Excitant, volatile toxic and harmful gas, 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 trigger the security incidents such as blast.
Therefore, if can design a kind of air it is automatic it is convenient blast, ammonia is not easy to leak 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
