Abstract
Refining operations present an opportunity for impurity removal from molten copper. Anode copper at Chuquicamata Smelter contains, at certain times, levels of As which is inacceptably high for the subsequent step of electrorefining. Several tests were carried out to implement the flux injection technique as a standard practice in the anode furnace. Test results for arsenic removal from molten copper and flux utilization as a function of several operational parameters are analyzed. Special reference is made to the effect of Na2O and CaO content in slag on the removal of arsenic and antimony. It is shown that the rate of removal content is dependent on the flux rate of injection into the copper. On the basis of the above, the flux injection rate is now calculated using an appropiate model.
