SANTIAGO (Reuters) - Global miner Anglo American Plc
Los Bronces, perched high in the Andes near Santiago, produced 416,300 tons of copper last year.
In the early hours of Monday, contract workers launched a protest against what they say are layoff threats and the London-listed miner's refusal to negotiate a series of demands. It is unclear how long the labor action could last.
The demonstrators lit fire to tires, damaged installations and looted during the protest, according to Anglo.
"Anglo American informs that due to the violent actions and damage that has occurred at Los Bronces, (the company) has decided to halt operations at Los Bronces to guarantee the safety of all the company's workers," the miner said in a statement.
"The process of halting the mineral-processing plants has started, and once finished the evacuation of workers will begin, in so far as we have safety guarantees for the internal and external roads," Anglo said, adding it had asked for authorities' help.
Anglo owns 50.1 percent of the deposit. Chilean state miner Codelco
Anglo American's other mines in world No.1 copper producer Chile are operating normally, the company added.
