Mill operations have been shutdown at MMG’s Century mine in Queensland following a zinc spill from a pipeline that transports slurry concentrates, the company said in a statement.
The failure in the pipeline, which transfers slurry from mine operations at Lawn Hill to the dewatering and port facilities at Karumba on the Gulf of Carpentaria, occurred at approximately the 115 kilometre point of the 304 kilometre pipeline.
Despite pumping being stopped upon discovery of the failure, there was still a discharge of zinc concentrate slurry at the area.
A spokesperson for Queensland’s Department of Environment and Resource Management told MINING DAILY officers are on their way to inspect the spill this morning and will announce results as they come to hand.
MMG said it is currently working to assess the length of time required to clean the spill and repair the fault in the pipeline.
Mining operations at Century will continue during the mill stoppage with ore stored on the ROM pad, and the company will continue to meet its customers’ requirements during the mill shutdown with concentrates stored at the Karumba port facility, MMG said.
