Premier African Minerals Limited (LON:PREM) has completed the installation of the X-Ray Transmission (XRT) sorter at its RHA tungsten mine in Zimbabwe.
Integration of the new sorter into the crushing circuits has now commenced and production of wolframite, the ore source for tungsten, is expected to start this quarter.
George Roach, chief executive, said the XRT sorter was an important part of the upgrades and improvements to the plant.
“Initial running of the sorter in situ has confirmed the identification and recovery of wolframite contained in ore and over the next period we will optimise the mineralisation identification criteria with the intention of increasing sorter recovery from the 82% we originally anticipated.
''Apart from the upgrades to the plant, we have restarted open pit mining and started building a stockpile of run of mine ore from the open pit and underground operations."
