TOKYO, March 25 (Reuters) - Mitsubishi Materials 5711.T said on Wednesday that it has decided to cease processing copper concentrate and operating the associated smelting facilities at its Onahama Smelter and Refinery by the end of March 2027.

The company expects to book an impairment loss of 21 billion yen ($132 million) in the fourth quarter of the current financial year ending this month, primarily relating to the fixed assets of the smelter, it said in a statement.
