Title
Behavior of Lead and Arsenic During Copper converting at TSUMEB Smelter
P . C . Chaubal , H . D . Baek, C . W . Won
Abstract
A computer model has been developed to simulate the behavior of lead and arsenic in the copper matte converting at the TSUMEB smelter. The analysis of the behavior of lead and arsenic was performed based on the previous modeling work and some thermodynamic data were updated and modifications made to meet the TSUMEB`s high lead and arsenic content in matte. Results of the simulation showed that the most of the lead and arsenic was removed in the slag blowing stage, and therefore the emphasis of this work is on the slow blowing. The predictions showed good agreement with operating data. Some discrepancies during early part of the slag blow were attributed to the reaction between the oxide slag (remained from previous batch) and matte before the slag blow.
