Arsenic content in copper concentrates is continuously increasing worldwide. It desirable to remove arsenic from the earlier stages of making due deposition cathode during electrorefining process. Effects temperature, flux, and oxygen on distribution converting fire refining processes were studied using FactSage 8.2. The results showed that can be effectively removed by proper selection slags. ...

Removing of arsenic and antimony from electrolyte copper electrorefining plant by cooling treatment is the subject current study. In this regards, temperature various samples reduce to 5, 10, 15 20 °C hold at different times without any turbulency. Experimental results reveal that decreasing electrolyte, facilitate deposition As Sb in form AsO5Sb, AsO4Sb As2O3 as white precipitate a critical ti...

Electrolytic copper refining makes it possible to obtain high purity metal, so the analysis of main ways impurity transition into electrolysis products is an actual problem. If solved, process can be controlled when changing composition raw materials and, as a result, content impurities in anodes. This paper uses comprehensive and synchronization large array data on concentrations various media...
