Glencore’s Jameson Cell coarse recovery at Antapaccay: key process notes for engineers

30 Second Briefing
Glencore Technology has validated a new coarse particle flotation application for the Jameson Cell at Glencore’s Antapaccay Tintaya concentrator in Peru, recovering copper-bearing particles from tailings that were previously lost. Pilot test work on the plant’s existing flotation tailings stream showed that the downcomer-based Jameson Cell can selectively float coarse copper sulphide particles that conventional cells struggle to recover. The approach targets declining head grades by extracting additional metal from installed circuits without major changes to primary grinding or rougher-scavenger configurations.
Technical Brief
- For Glencore, the concept is being assessed as a bolt-on recovery step at other copper concentrators.
Our Take
In our database, Glencore Technology’s Jameson Cell has recently been reported moving into primary rougher duties and AI-ready configurations, so demonstrating coarse particle recovery on copper at Antapaccay’s Tintaya Concentrator in Peru signals that the same platform is now being stretched across both duty and particle-size envelopes.
The Hermosa project item from August 2026 shows South32 choosing a Jameson Cell-based concentrator for critical minerals, and pairing that with copper test work at Antapaccay suggests Glencore Technology is positioning the Jameson flowsheet as a standard option for new-build and brownfield base-metal plants looking to cut energy and footprint.
With Jameson Cells already deployed at Mogalakwena North for platinum and now being trialled on copper in Peru, Glencore Technology is building a multi-commodity reference base that will make it easier for Latin American copper operators to justify retrofits on sustainability grounds rather than purely on incremental recovery gains.
