Noranda Aluminum Holding has idled two of three potlines at its New Madrid, Missouri smelter after an electrical supply circuit failure, the company said in a statement on Friday.
The failure occurred on Thursday afternoon and no serious injuries were reported, the company said. The facility has a capacity to produce 253 000 tonnes of aluminium each year, but has been operating at around 85% of capacity for the past several months with no plans to ramp up to full capacity.
