Flotation circuit rebuild raises recovery on complex ore bodies

Flotation circuit rebuild raises recovery on complex ore bodies

A staged rebuild of grinding and separation stages has improved recovery consistency on variable feed, with tighter quality documentation at every step.

Complex, variable feed is the hardest problem in mineral processing. Recovery figures that look strong on a clean sample often collapse when the ore body shifts. Our engineering team spent the last two quarters rebuilding a client flotation circuit specifically to hold performance across that variability.

The work covered crushing and grinding optimisation, a reconfigured separation and concentration sequence, and new sampling points feeding the on-site quality laboratory. Every change was documented against the existing ISO-certified testing protocol so results remain auditable for offtake partners.

Recovery consistency, rather than peak recovery, was the design target. Steadier output makes downstream logistics and contract commitments easier to honour, and it reduces the volume of material returned for reprocessing.

The same methodology is now being applied to two further facilities in our technical services pipeline.
