A technical and operational audit of the First ten years of the Teniente converter operations at Nkana smelter

摘要

The CT has been a successful project and its operation after the introduction of the flash dryer and bone dry concentrate injection into the CT has demonstrated a great potential. The increased smelling capacity will enable Nkana smelter to phase out two operating reverbs and remain with one reverb that will be saved as a slag-cleaning vessel. This will effectively reduce smelling energy requirements and the overall cost of copper production The CT technology has a high sulphur recovery and has resulted in an increase in acid production to support copper production at KCM's TLP From the environmental point of view, the CT is a clean technology; the increased sulphur recovery has reduced sulphur emissions to satisfy Nkana smelter's environmental legal requirements. The CT is flexible in the options of the quality of the feed materials and operating parameters. It ability to operate on both green charge and bone-dry concentrates has.surpassed the imagination of the Nkana smelter metallurgist.
