In the metals segment, which was the business that started Furukawa, we are focusing on the stable supply of copper, which is essential for social infrastructure.

  • Electrolytic copper is produced through entrusted smelting.
  • The production volume of electrolytic copper is around 70,000 tons each year.

Electrolytic copper

Since electrolytic copper is superior in electric conductivity and workability, it is used in a wide range of electrical wires and wrought copper and copper alloys.

Electrolytic copper

Gold , Silver

We sell the gold and silver contained in copper ore. We separate out and recover the gold and silver contained in the copper ore during the smelting process, convert it into products in a precious metal factory and then sell it.



Sulfuric Acid

Sulfuric acid is used as an indispensable basic material in each sector of the chemical industry. The metals segment recovers the sulfurous acid gas generated in the copper ore smelting process and produces sulfuric acid.

Furukawa Metals & Resources Co., Ltd.

Inherited the metals business of the Furukawa Company Group and manufactures and distributes electrolytic copper, gold, silver and sulphuric acid. The Metals segment of the Furukawa Company Group originated at the time of its foundation dating back to when we started operations at the Kusakura Copper Mine in Niigata Prefecture in 1875 and the Ashio Copper Mine in Tochigi Prefecture in 1877. Among various cutting-edge technologies developed at the Ashio Copper Mine, Furukawa/Outokumpu flash smelting is highly-acclaimed as one of the top-level technologies in the world. This low-cost, low-pollution technology was developed into a commercially-based technology in 1962 and has been adopted in a number of smelters in Japan and abroad.
In 2004, the metals business of Furukawa Co., Ltd. was spun off, and Furukawa Metals & Resources Co., Ltd. was founded.
We purchase copper concentrates, which are our main raw material, from overseas and outsource the smelting process to Onahama Smelting and Refining Co., Ltd., Hibi Kyodo Smelting Co., Ltd. and others that we invest in. We therefore have a geographically optimal production system for copper and sulphuric acid in Japan. We are currently aiming to further improve revenue conditions and we are working on establishing an optimized production/distribution system focusing on profit margins.
