Production of cobalt from copper-cobalt ores on the African
Three generic processing classes currently used to produce cobalt on the Copperbelt. The first generic flowsheet, in which the mined ore is treated hydrometallurgically to produce copper cathode and cobalt hydroxide, is currently the most common configuration used for cobalt.

Copper production was 12,139 tonnes in Q1 2023 (Q1 2022: 11,461 tonnes), compared with 13,969 tonnes in Q4 2022. Production previously anticipated for Q1 2023 is now expected in Q2 2023, as a result of the rescheduling of plant maintenance activities. On-site copper concentrate inventories at the end of Q1 2023 were approximately 1,564
