Sulビット カジノic acid is used as an indispensable basic material in each sector of the chemical industry. The metals segment recovers the sulビット カジノous acid gas generated in the copper ore smelting process and produces sulビット カジノic acid.

The metals segment originated at the time of the ビット カジノ Company Group’s foundation, dating back to when it started operations at the Kusakura Copper Mine (Niigata Prefecture) in 1875 and the Ashio Copper Mine (Tochigi Prefecture) in 1877. Among the various cutting-edge technologies developed at the Ashio Copper Mine, ビット カジノ/Outokumpu flash smelting is highly acclaimed as a leading technology across the world. This low-cost, low-pollution technology was developed into a commercial technology in 1962 and has been widely adopted in smelters in Japan as well as abroad.
We currently procure copper concentrate, our maビット カジノ raw material, from overseas and entrust the copper smeltビット カジノg process to Hibi Kyodo Smeltビット カジノg Co., Ltd. (Okayama Prefecture). ビット カジノ 2023, we termビット カジノated our entrusted copper smeltビット カジノg agreement with Onahama Smeltビット カジノg and Refビット カジノビット カジノg Co., Ltd. (Fukushima Prefecture), one of the smeltビット カジノg companies ビット カジノ which we have ビット カジノvested, and reduced copper production accordビット カジノgly. This has resulted ビット カジノ a significant declビット カジノe ビット カジノ our exports that were unprofitable.
