RHA plant upgrades completed
JOHANNESBURG (miningweekly.com) – Aim-listed Premier African Minerals has completed plant upgrades at its 49%-owned RHA tungsten project, in Zimbabwe.
The screens, plant modifications and electrical reticulation works have been completed and the plant is undergoing a phased commissioning and optimisation process to achieve the anticipated recoveries and operational throughput.
The miner noted that wolframite concentrate from ore from the underground mine had already been produced and that the throughput of the plant would steadily be increased to the plant's design capacity of 16 t/h.
Meanwhile, X-ray transmission (XRT) test work was also recently conducted on bulk sample material from RHA, which was rerun at the express direction of the equipment provider to confirm previous results.
“The equipment provider now confirms that the sort achieved a near 100% recovery. Premier is reassessing the pit capacity to meet the minimum tonnage XRT sorting will require and expects to be in a position to progress this in early August,” CEO George Roach said.
