Ceibo Delivers First Copper Cathode Using Sulphide Leaching Technology in Chile

Ceibo

Innovative Technology Targets Low-Grade Copper Ores

Ceibo, a Chilean copper extraction technology firm backed by Australia’s BHP, has produced its first copper cathodes from a sulphide-leaching operation at Minera San Geronimo (CMSG) in northern Chile. The demonstration plant, constructed earlier this year, employs Ceibo’s proprietary technology to increase copper recovery from low-grade ores without major infrastructure upgrades. This innovation comes as the mining sector seeks efficient, lower-impact solutions to sustain long-term production.

Addressing Global Copper Supply Challenges

Ceibo’s technology has already achieved a 75pc recovery rate in under a year, showing strong potential for commercial scalability. The Paris-based IEA forecasts copper demand to grow by 30pc by 2040, with a looming 30pc primary supply deficit expected by 2035. As a result, technologies like sulphide leaching could play a critical role in bridging the supply gap while reducing environmental impacts. Several global firms are pursuing similar methods to boost extraction efficiency and meet accelerating demand from clean energy, EVs, and infrastructure projects.

The Metalnomist Commentary

Ceibo’s milestone is a timely development for Chile’s copper sector, particularly as high-grade reserves decline. If scaled successfully, this technology could help secure Chile’s position as a leading copper supplier while mitigating environmental concerns and meeting the mining industry’s sustainability goals.
