Resolute completes sulphide plant work at Syama
PERTH (miningweekly.com) – Gold miner Resolute Mining on Friday announced the completion of the Syama sulphide plant shutdown, in Mali, completing its A$7.5-million enhancement project at the gold plant.
The shutdown started on February 18, with the comminution circuits fully recommissioned by March 20, ahead of schedule.
Resolute told shareholders that flotation concentrate has been stockpiled in advance of the roaster restart to provide immediate gold concentrate feed. The full restart of the roaster was delayed by three days to account for revised recommendations from the refractory suppliers resulting in a more conservative refractory installation and curing process.
First gold concentrate was fed to the roaster on March 31, completing the restart of the entire sulphide processing circuit.
The miner said on Friday that the performance of the entire sulphide plant is now expected to be more consistent and manageable, as measured by the overall plant availability, leading to improved production outcomes. Roaster capacity is also expected to increase which will effectively move the sulphide circuit ‘bottleneck’ from the roaster to the crusher.
Following a detailed review of the integrity of the roaster, use of condition monitoring controls and the properties of the newly installed refractory it should be possible to extend the next major shut and refurbishment of the roaster by up to seven years, improving the production profile of the Syama sulphide project and life-of-mine fundamentals.
