【Copper ore beneficiation】Working toward the effective use and stable supply of copper resources
Flotation plant design for stable operation with a high recovery
To ensure a stable supply of copper resources, we are producing copper concentrate from the ATACAMA KOZAN Mine in Chile and have plans to bring the Arqueros Mine, a new development project, online during FY2026.
The Arqueros Mine is characterized by its reserves of multiple copper minerals. Different copper minerals behave differently in the flotation process, prompting concern that variation in mineral composition during operations could destabilize the copper recovery.
We addressed this issue using Mineral Liberation Analyzer (MLA) and plant simulation software to improve the copper recovery and establish plant design and operating conditions capable of accommodating variation in mineral composition.
Stable operation at a high recovery reduces environmental impact and stabilizes the supply of copper resources, contributing to the achievement of a carbon-neutral society.
