Mitsubishi Materials will reduce primary copper smelting volumes by 30 to 40 percent by 2035

Mitsubishi Materials, a Japanese company, said it would shift its focus to secondary smelting in order to increase profitability.

Due to a tight supply of concentrates and the expansion of smelting capacity by China, Japanese copper smelters face a tumbling treatment charge and refining charge (TC/RC) as well as shrinking smelting profits.

Mitsubishi Materials announced in October it would cut the refined copper production at its Onahama Smelter & Refinery in the period October-March by a quarter.

It plans to integrate its copper products sales and procurement of copper concentrates with rival Pan Pacific Copper owned by JX Advanced Metals Mitsui Mining and Smelting and Marubeni.

Mitsubishi Materials announced a new three-year business plan beginning in April. The company said that it would shift its primary copper operations into secondary smelting by using electronic waste. It will also explore the possibility of building new secondary melting plants in Europe and America to boost growth.

The secondary smelting process produces copper by recycling materials, rather than mining ore.

Tetsuya Tanahka, President of Japan, said at a press conference that the low TC/RCs will continue. This makes the move to profitable eScrap processing vital for our sustainable growth. E-scrap is electronic waste, such as old computers, smartphones, and home appliances.

He said: "We will quickly shift our focus from volume to quality. We'll transition our revenue structure from processing copper concentrate to secondary smelting, and optimise production systems and business portfolio."

Tanaka stated that the company plans to double its secondary smelting capacities by 2035. However, it expects to see a drop of 20-30% in its annual refined copper production from around 400,000 metric tonnes due to a reduction in primary smelting.

Mitsubishi Materials is also expanding its global tungsten business by increasing recycling capacity in Europe, and constructing new U.S. recycling facilities for the rare metal used in batteries and defense.

Tanaka stated that by achieving a 100 percent recycled material rate in our tungsten production sites outside China, we will meet the rising demand and increase profitability. (Reporting and editing by Kirsten Doovan; Yuka Obayashi)
