Top copper producer Codelco is again delaying the return to normal operations at its Chuquicamata smelter. Some parts of the smelter are operating normally, including the flash oven and one acid plant, a Codelco official said in an email in reply to questions from Bloomberg. A second acid plant will start ramping up within the next six days and the whole facility is expected to be up and running within the third quarter, the company said.
