Kipoi debottlenecking to raise output to 32 500 t/y

A study for the debottlenecking of the Kipoi solvent extraction and electrowinning (SX-EW) plant, in the Democratic Republic of Congo, has revealed that copper production could be increased from the nameplate capacity of 25 000 t/y to 32 500 t/y. Project owner Tiger Resources on Friday said the debottlenecking project, which would require a capital investment of some $25-million, could result in an average life-of-mine operating cost of $1.27/lb.
