Strict targets set for mines and smelting operations

China will shut down about one-fifth of its rare earths production capacity under new industry rules, but analysts fear that their strict implementation could see production further eroded.

Mixed-type rare earths mines, mostly located in North China, will have to have a minimum annual production capacity of 20,000 metric tons a year and smelting companies will have to ensure an annual output of at least 2,000 tons, according to a statement by the Ministry of Industry and Information Technology on Monday.
