Concentrator overhaul on track at Capricorn Copper

Concentrator overhaul on track at Capricorn Copper Coarse ore stockpile feeder repairs are being undertaken during the shutdown.

Capricorn Copper has launched a week-long maintenance shutdown on its processing plant, with about 80 contractors joining 80 of the operation’s own Ausenco workforce for the job.

Concentrator manager Marvin Muller from Ausenco said the shutdown was the biggest in the processing plant, 125km north of Mount Isa, since the copper mine was restarted in 2017.

“We are completing more than 300 different jobs using our own Ausenco workforce and 12 local companies from Mount Isa, Townsville and Cairns,” he said.

The scope of works includes a mill reline, stockpile feeder maintenance, flotation cell re-rubbering and various chute repairs.

“Our focus is on having an injury free shutdown,” Mr Muller said.

The work began on October 15 and is running around the clock for seven days.

Ausenco has been in charge of the operation and maintenance of the concentrator at Capricorn Copper since the start of this year,

Mr Muller said they had achieved a 40-50 per cent increase in throughputs and a 50 per cent improvement in final concentrate grade in that time.

Mill availability is up 11 per cent and they have achieved a 10 per cent reduction in processing costs.

The Capricorn Copper operation, at Gunpowder, was known as Mount Gordon under former owner Aditya Birla.

Lighthouse Minerals and EMR Capital took control in October 2015 and launched a $110 million restart as Capricorn Copper.
