Progress in the Hitachi Metal Recycling Complex Project and other developments

Nippon Mining & Metals Co., Ltd., (Headquarters: Toranomon 2-chome, Minato-ku, Tokyo; President and Chief Executive Officer: Masanori Okada) and Nikko Environmental Service Co., Ltd. (Headquarters: Miyata-cho, Hitachi-shi, Ibaraki; President: Kazuhei Sakamoto) are promoting the Hitachi Metal Recycling Complex (HMC) project, the first phase construction of which has been completed on schedule. The second and third phases of construction are also proceeding according to plan.

The Nippon Mining Group has also launched the Hitachi Area Redevelopment Plan in the Hitachi area where the HMC project is located. Under the plan, construction of a new Technology Development Center building was completed in August, 2008, and an administrative office will be built by April, 2009. The entire plan is scheduled to be finished by the end of March, 2010.

The facility completed in the first phase construction of the HMC project recovers antimony, bismuth, tin, nickel and other metals from intermediate products generated during the smelting and refining process at the Saganoseki Smelter & Refinery, and recycled materials treated through the pyro-metallurgical process of Nikko Environmental Service. It started test operation just after completion in August 2008, and will move to commercial manufacturing in November, 2008. Since recovered metals will be raw material for our Electronic Materials Business, the HMC Works will play an important role as a stable supply source for the Business.

The Nippon Mining & Metals Group is actively promoting a recycling-oriented society through the strengthening of Recycling and Environmental Services, the streamlining of the smelting process at the Saganoseki Smelter & Refinery, and the securing raw materials for the Electronic Materials Business through the HMC project.

Outline of the HMC project

1.The process used in the HMC Project
The Group has developed a unique complex process through the combination of pyro-metallurgical and hydro-metallurgical processes, enhanced smelting and refining,
and recycling and environmental services, to achieve zero-emission recycling.
Under the HMC project, this unique process enables us to recover various valuable metals from recycled raw materials.

Outline of the Hitachi Area Redevelopment Plan

Having marked our 100th anniversary in 2005, the Hitachi Area Redevelopment Plan was launched for our business base as we look ahead to the next 100 years. The plan, aiming to streamline and reinforce operations, strengthen technology development activities and upgrade infrastructure, includes demolition, rebuilding, relocation and construction, and the expansion of production capacity.
1.Facilities in the area
The Hitachi area has been divided into three zones, with buildings and facilities clustered within each zone enabling efficient and flexible management of each business in each zone.
・Dioin district   Recycling and Environmental Services area
・West-Shibauchi   district Copper Refining Business area
・Shirogane, East-Shibauchi area   Hi-tech / Technology Development area
2.Functional enhancement through the expansion of production capacity
a. Launch of the HMC project in recycling and environmental services
b. Construction of new plating lines in the precision plating business
c. Expansion of research facilities at the Technology Development Center
