What are arterial and venous businesses?
Venous businesses recover, recycle, and reuse used products. Arterial businesses create new ones. The
businesses were named by equivalating the flow of their materials and products to blood circulation.

PROCESS

Resource procurement
Embracing both
natural sources
and urban mines
Through continuous investment in mines, we are working to ensure a stable supply of copper concentrates, which are raw materials for copper smelting.
In addition, we boast world-class processing volume for E-Scrap, which refers to waste electronic circuit boards from urban mines. We will procure precious raw materials for smelting non-ferrous metals, including copper, from both natural sources and urban mines.

Decomposition and separation
Decomposing complex
metal compounds
We have developed the home appliance recycling business based on our mine and mineral processing techniques, which have been cultivated over many years. We utilize our advanced skills for decomposing and separating used products.
Decomposition and separation
Smelting
Maximizing the potential
of materials
Our strength in smelting led to the development of our world-renowned proprietary technology, the "Mitsubishi Continuous Copper Smelting Process."
With these technological capabilities, we are able to produce high-quality electrolytic copper, gold, silver, tin, and other metals from E-Scrap and ore.

MANAGEMENT STRATEGY
Guideline to achieve Our Commitment
Medium-term Management Strategy FY2031 ("the FY2031 Strategy")

To Fulfill Our Commitment
to the Future
What is the Material Grid?
To efficiently recover desired materials, multiple smelting bases are interconnected like a grid, enabling the exchange of valuable metals between them. In recent years, with the expansion of recycled product processing, the types of raw materials that can be recycled into metal resources has increased. In addition to copper smelting, Mitsubishi Materials is involved in various smelting businesses in Japan and overseas, including previous metals smelting, lead smelting, and tin smelting, and the variety of metals handled at each smelting site is increasing. This interconnected network of smelting bases, known as the Material Grid, is one of Mitsubishi Materials' strengths.
What is the "Mitsubishi Process"?
The smelting (S) furnace, slag cleaning (CL) furnace, and converting (C) furnace are connected by the launders, transforming the conventional batch operating method into a single, continuous copper smelting process. This has made the facility more compact, allowing for energy-saving and low-cost operations. In addition, it prevents the leakage of sulfurous acid gas, meaning that it is non-polluting.

High-performance Products Help Advance Automobiles and Semiconductors
The evolution of next-generation vehicles and electronic devices is remarkable. Regarding semiconductors, which control their motion, and the components and parts through which electricity flows, materials and products are required to be more precise than ever and capable of functioning under severe conditions. In other words, the advancement of materials is essential for the evolution of automobiles and electronic devices. Mitsubishi Materials supports this evolution by developing and manufacturing high-performance products with a wide range of features.
Automobiles
Since xEVs use a significant amount of electricity for power and electronic control, the materials used in them must demonstrate conductivity and heat dissipation properties in all environments. Mitsubishi Materials tackles this challenge through high-quality copper products and alloy metal technology.
Semiconductors
Semiconductors control and manage memory in various electronic devices. The completion of integrated circuits, which serve as the brain of computers, involves a wide range of processes. These include not only manufacturing the underlying materials but also creating equipment for manufacturing semiconductor components. Mitsubishi Materials develops and produces materials and processed products used in various applications related to semiconductors.
