| titleOfInvention | A kind of method that copper anode mud control current potential detaches and is enriched with tellurium |
| abstract | A kind of method that copper anode mud control current potential detaches and is enriched with tellurium, copper anode mud roasts after being stirred by a certain percentage with the concentrated sulfuric acid under different temperatures gradient, calcining is milled to require granularity after in dilution heat of sulfuric acid using control current potential mode be added hydrogen peroxide oxidation leaching, copper powder displacement is added using control current potential mode in copper leached solution, tellurium is set to be enriched in replacement slag, displaced liquid electrodeposition recycles Returning utilization after copper.The essence of the present invention is to realize Oxidation Leaching and the copper powder displacement adjustable controllable purpose of two processes respectively using control current potential mode, the leaching rate of control current potential Oxidation Leaching process copper and tellurium reaches 99.0% and 80.0% or more, and the replacement rate of control current potential copper powder replacement process tellurium reaches 99.0% or more.The present invention has the advantages that technical process technical indicator is stable, labor intensity is small low with production cost etc.. |
