| Abstract Scope |
In 2019, the construction and commissioning of what was to be the world’s first commercially operated ISACONVERT™ furnace was completed at the Kansanshi Copper Smelter.
Between 2019 and 2021, the ISACONVERT™ furnace was operated in four campaigns in which the matte treated steadily increased from average of 35 tonnes per day to an average of 245 tonnes per day. Blister tapping and slag tapping were among the areas that had many challenges and initially had a negative impact on the plant availability. Frequent failures to close the tapholes and hot metal spills were experienced, giving rise to serious safety concerns. Several changes were implemented that resulted in a significant improvement in safety for the tappers as well as a reduction in plant down time
This paper describes the design and operation of the ISACONVERT™ blister and slag tapping systems and the improvements that led to successful operation of the furnace. |
