BOGOTA, April 17 (Reuters) - BHP Billiton has shut an oven its Cerro Matoso ferronickel plant in Colombia after equipment was damaged, cutting output by as much as three quarters, the president of the union representing the plant's workers told Reuters on Friday.
Damage to a crane stopped production of one of two ovens on Thursday afternoon, union leader Domingo Hernandez said. (Reporting by Julia Symmes Cobb and Nelson Bocanegra; editing by Josephine Mason and Alden Bentley)
