Abstract

This paper describes the successful test operation of a 50 t/h concentrate feed rate (or on the anode copper basis 9000 tlm) with the Mitsubishi Process. Particular emphasis is given to the analyses of the furnace capacity by the measurement of flow pattern and oxygen potential. Smelting rate on the unit hearth area of the smelting furnace is now one-ton of concentrate/m2·h. The results of the analyses show the further potential of the furnace capacity of the process.
