Electrolytic copper solution extraction nickel iron technology and equipment selection
In the process of electrolytic copper processing production, if the content of nickel and iron is high, will directly affect the quality of the copper, so you need to electrolytic copper nickel and iron in the solution is extracted, in order to improve the quality of the electrolytic copper.
for electrolytic copper nickel and iron in the solution is commonly used methods for the extraction of solvent extraction.
This method is to use an extraction agent, will shift the electrolytic copper solution of nickel iron extraction agent, and then to pick up the extraction agent, so as to achieve the extraction effect.
nickel iron extraction process, will first electrolytic copper solvent to adjust PH value, choose suitable extractant, electrolytic copper solution and extraction agent according to certain compared through different feeding tube into the centrifugal extraction machine, by centrifugal force, two phase liquid rapid mixing and mass transfer, electrolytic copper nickel and iron in the solution of transfer to the extraction agent, by centrifugal force, two phase liquid separation, in outlet the body weight, complete the extraction process.
section can be carried out after extraction, extraction solvent and nickel iron organic phase separation, extraction solvent can be recycled to recycle, and nickel and iron can also be through the processing finished products.
here centrifugal extraction machine is designed and developed by zhengzhou days extraction. cwl - production
M series new centrifugal extraction machine, this extraction machine is modified on the basis of traditional extraction equipment upgrade, the working principle of has essential difference with the traditional extraction equipment, mainly the use of centrifugal force for rapid mixing separation of two phase fluid, mixing and mass transfer is fast, high extraction efficiency.
M series centrifugal extraction machine performance advantages are:
1, simple structure, stable -
Using suspension single fulcrum structure, processing area at the bottom of the bearing and mechanical seal, no leakage risk, solved the centrifugal extraction machine failure frequently, the problem of short service life, save the costs for equipment maintenance.
2, energy saving,
Capacity bigger, more energy saving,
Under the condition of same capacity, its power consumption is a traditional annular structure of centrifugal extraction machine 1/10 ~ 1/3)
3, corrosion resistance,
Equipment is available in using perfluorinated polymer materials, resistant to strong acid,
Hydrochloric acid and mixed acid, etc. )
4, mixing, separation effect is good,
A variety of hybrid structure is optional, high separation efficiency, can be applied to easily emulsifying system.
5, heavy phase weir plate easy to change -
Material system changes, the heavy phase weir plate can realize quick change, the operation is simple and convenient.
6, equipment to save small amount of liquid -
The effective volume of equipment.
7, a high degree of automation,
Can realize online real-time monitoring equipment operation data, can be selected in accordance with GMP standard online cleaning system, fully able to adapt to the intermittent and continuous operation.
