SANTIAGO, July 28 (Reuters) - Codelco's Chuquicamata copper mine returned to normal operations on Tuesday afternoon after a contract workers' strike caused a halt earlier in the day, the company said in a statement.
All projects except the small Salvador mine were operational, although there had been "various difficulties" during the day, it said. (Reporting by Rosalba O'Brien; Editing by Chris Reese)
