Mitsubishi Materials will end certain Onahama smelter activities by March 2027

Mitsubishi Materials announced on Wednesday that it would stop processing copper concentrate at its Onahama facility - and all related smelting operations - by the end of March 2027.

Mitsubishi Materials stated that the outlook for business was becoming more uncertain due to an intensifying competition with overseas smelters, and a steep decline in treatment and refinement charges (TC/RCs).

It is expected to book an impairment loss of 132 million yen (21 billion yen) in the fourth quarter of this year's financial year, which ends on the end of this month. This loss will be mainly due to the fixed assets of the smelter.

Fees paid by miner to refine concentrate, known as TC/RCs (Transfer Charges/Refined Metals), are under pressure due to the rapid expansion of global smelting capacities, led by China. This has squeezed margins.

Mitsubishi Materials, as part of its structural overhaul, decided to stop concentrate processing at the plant that has been operating since 1965.

The Electrolytic Plant will continue to refine scrap copper anodes as well as anodes produced by the group. The 'platinum group' metals recycling plant, as well as the foundry that produces copper ingots will continue to operate.

The smelting margins of Japanese copper smelters have been shrinking as TC/RCs are in a downward spiral.

JX Advanced Metals, its partners and Mitsubishi Materials announced in November that they planned to integrate Mitsubishi Material's copper concentrats procurement, as well as copper product sales, into Pan Pacific Copper.
