Oyu Tolgoi concentrate thickener rake arms fail again

Turquoise Hill Resources, a subsidiary of diversified major Rio Tinto, on Tuesday reported that the rake arms in one of the two tailings thickeners at the Oyu Tolgoi copper/gold mine  had failed again. Having started production during last year, output at the massive mine was heavily impacted by post-commissioning issues during the first quarter, including rake blade failures in the tailings thickeners, which caused the shutdown of one production line for about seven weeks.
