Centrifugal extraction machine in hydrometallurgy extraction of copper
Modern wet industry including leaching - brass
Extraction of extraction -
Electrical product of three parts, constitute three loops, extraction is a key part of the essential, it is the result of the development of extraction technology, to create a modern centrifugal extraction machine of copper hydrometallurgy in the new situation.
Leaching, acid reaction with copper ore copper dissolved into solution, copper ion in extraction process and extracting agent proton exchange, into the organic phase, protons into aqueous solution, extraction liquid acidity to improve.
Extraction residue return to leaching.
copper power product of organic phase load residual liquid extraction, get rich the electrolyte, the acidity of electrolyte, and bringing back extractant acid form, return to the centrifugal extraction machine of copper hydrometallurgy in the extraction process.
Electric product process, copper cathode, anode oxygen precipitation and mole of sulfuric acid, etc.
So, from the point of view of chemical reaction, runs through the whole process of copper ions and proton exchange and replace, the reverse movement.
Electrical product produced by the proton consumption in ore, leaching of copper in the ore for the final product.
centrifugal extraction machine in hydrometallurgy extraction technology of copper to copper hydrometallurgy has brought the revolutionary change, create the modern wet copper metallurgical industry.
Since the 1970 s development, has become an independent industrial system, the annual production of copper of over hundred t, 2. 5 million t at the turn of the century, the annual production of copper 15%, accounting for 17% of the copper directly by the mine production.
Its development speed is much higher than the overall development of copper industry.
