| Abstract | A brand new process of blister copper production at copper mattes and concentrates treatment in tow-zone Vaniukov Converter has been developed at Gipronickel Institute facility. Thermodynamic analysis of exchange interaction has been performed for «slag melt — metal phase formed in the over-the-lance area of Vaniukov Converter reduction zone» system and for «slag melt — bottom phase of blister copper located in the bottom (under-the-lance) area of Vaniukov Converter» system. Based on the thermodynamic analysis data, the original design of two-zone Vaniukov Converter has been proved to be able to create conditions ensuring production of blister copper of higher quality, as compared to one-zone Vaniukov Converter process, copper concentration in slag being substantially lower. |
