Chambishi smelter ENRC
saleable cobalt concentrate production was 2,173 t and saleable cobalt metal
production from Chambishi was 1,190 t. The increased rate of production against Q2
2010 reflected higher ore grades.
The commissioning of the cobalt solvent extraction and electrowinning (‘SX/EW’)
plant is planned for December 2010, with the plant reaching steady state production
in Q2 2011. In Q3 2010, additional heap leach pads became operational and were
being stacked with cobalt rich ore which will eventually be converted into cobalt metal
through the SX/EW plant. In addition, grade A copper cathode will be produced as a
by-product. The SX/EW plant has a planned capacity of 3,000 t of cobalt metal and
4,400t of copper grade A cathode per annum.
Vu dans les résults de ENRC, par contre c'est bien un smelter donc il prend seulement une marge sur le raffinage
