Kansanshi Mining plc's copper smelter in Solwezi, Zambia started production in March 2015 and has now been operating for over two years. The sulphuric acid plant has performed well during this period with an average availability of about 93%. However, issues arose in the plant which were not evident during the design phase and became evident only after operation for an extended period, predominatly around the converter. Other areas where operating issues were encountered were wet electrostatic precipitator performance, blower power consumption, converter bed temperature profile, and converter internal duct reinforcement. This paper provides details on the issues and the solutions implemented.

Palabras clave : sulphuric acid plant; converter bed temperature; wet electrostatic precipitator; acid mist capture; preheater.
