Caserones copper mine in Chile says to close copper concentrator

Caserones copper mine, in Chile, said on Tuesday that it would temporarily shut down its copper concentrator in order to replace a leaking pipe. The Environmental Tribunal of Antofagasta, a province of Chile's northern mining region, asked Lumina Copper, which owns the mine, to shut down the processing plant for 15 days following a tailings spill into a nearby river, Caserones said in a statement.
