Katanga Mining increased its copper cathode production to 57 175 t in the first quarter of this year, compared with the 49 770 t produced in the fourth quarter of 2018, but output of cobalt contained in hydroxide decreased to 3 511 t, from the 4 646 t produced in the fourth quarter of 2018. The company’s 75%-owned Democratic Republic of Congo (DRC) subsidiary Kamoto Copper Company (KCC) temporarily suspended the export and sale of cobalt in the fourth quarter of last year owing to the presence of uranium detected in the cobalt hydroxide at levels exceeding the acceptable limit allowed for export.
