Process ownership – SX and EW

Act as the engineering owner of the SX and EW circuits, including mixer-settlers, organic and electrolyte handling, tank house, cell house and associated utilities.

Monitor daily plant performance (PLS grade and flow, extraction and stripping efficiency, phase continuity, entrainment, current efficiency, cathode quality) and act on deviations.

Define and maintain operating envelopes, control set points and alarm limits together with operations and control engineers.

Lead technical troubleshooting of process upsets such as crud formation, organic degradation, impurity build-up (Fe, Mn, Cl, NO3), short circuits and poor cathode morphology.

Manage reagent strategy for extractant, diluent, smoothing agents and cobalt sulfate, including consumption tracking and supplier technical liaison.

Produce daily, weekly and monthly process performance reports and metallurgical balances.

Process improvement

Identify, evaluate and lead improvement projects that increase recovery, throughput, current efficiency and cathode grade, or reduce energy, reagent and operating costs.

Use data analysis, mass and energy balances, and process modeling to quantify opportunities and build business cases.

Plan and run plant trials and test work with the laboratory, vendors and external partners, then implement and verify results.

Drive root-cause analysis on recurring losses and production incidents, and track corrective actions to closure.
