Jubilee Metals Group is replicating its modular concentrator strategy at its Zambia copper operations, following the success of the strategy in the group's former platinum operations in South Africa.

JSE-listed Jubilee Metals Group, which has copper operations in Zambia, said its Roan concentrator has returned to full operations following a maintenance shutdown in May, and measures have also been put in place to mitigate rising fuel and acid prices.

The group said in an update on Thursday that it is targeting a processing run rate of 30,000 tons per month of (run-of-mine) ROM, with increased copper oxide recovery rates due to the expanded flotation circuit.

"The successful progression of the Roan dewatering circuit through commissioning and ramp-up marks another important milestone in the expansion of our Zambia copper operations,” said CEO Leon Coetzer in a statement.

The maintenance activities at Roan had focused on the ROM feed circuit and maintenance of the internal pumping mechanisms of the flotation units, as well as final modifications to the new dewatering circuit for the fines concentrate.
