Freeport-McMoRan Inc.’s output fell at its Grasberg complex in Indonesia, the world’s third-largest copper mine, after some employees stayed away in protest at safety standards following a fatal accident last month.

Operations at the open pit at Grasberg, which also produces gold, were interrupted for about two weeks after a Sept. 27 collision between a light vehicle and a truck killed four workers.
