The oxidation mechanism in copper smelting and converting
|
The oxidation mechanism of copper-sulfide concentrates is of fundamental interest in an understanding of flash smelting and converting. The compositions of mattes follow simple, well-defined relationships, and the progression of iron and sulfur oxidation in smelting and converting occurs in such a manner that generates mattes of these compositions.
INTRODUCTION
Despite past efforts to define the mechanism of oxidation of copper sulfide concentrates in flash smelting, a clear and consistent picture remains illusive.l Too often, studies to determine this important aspect of copper smelting ...
