Metallurgist
Optimizes concentration and recovery processes by integrating lab analysis with plant operating variables.
What does a Metallurgist do?
- Performs daily metallurgical balances and reconciles plant production against feed, concentrate, and tailings grades
- Plans circuit sampling campaigns to identify at which stage of the process payable metal is being lost
- Characterizes the behavior of new ores at lab scale before they enter the industrial circuit
- Evaluates alternative reagents and operating conditions with suppliers and validates their performance through comparative tests
- Writes and updates process operating standards once an improvement is validated and implemented
- Accompanies operators in the control room and in the field to ensure setpoint changes are applied as designed
Ideal OCEAN+ Profile
Extractive metallurgy requires ongoing investigation to improve recoveries and adapt processes to ore variability
Precision in test design, variable control, and results documentation is critical for reproducibility
Technical-analytical work; communicates with operations, lab, and management but without continuous high-visibility exposure
Smooth coordination with the plant superintendent, operators, and external assay contractors
Tolerance for test campaigns with unexpected results and pressure to optimize recoveries quickly
Metallurgical work demands consistent test protocols and disciplined recording of process parameters; changes to plant regime are validated through method, not intuition
Strengths and Red Flags
Strengths
- Design and execution of metallurgical tests (flotation, leaching, cyanidation) with statistical control
- Diagnosis of recovery drops through mineralogical and circuit analysis
- Implementation of process improvements that directly impact operating margin
- Integration of lab data with operational variables for predictive plant models
Red Flags
- Excessively theoretical approach without the ability to translate improvements to the plant floor
- Resistance to sharing negative findings that contradict prior hypotheses
- Difficulty prioritizing improvements with economic impact over minor technical optimizations
- Frequent conflicts with operations over process changes implemented without consensus
What does a successful Metallurgist do?
The behaviors that separate top performers from average in this role, and the OCEAN+ profile dimension that explains them.
Looks for the explanation of a process deviation in mineralogy and historical data before accepting the first plausible cause
OpennessHigh Openness in this range keeps multiple explanations alive in parallel, avoiding optimization of the symptom instead of the cause
Repeats a test with favorable results before presenting it, to confirm the effect wasn't sampling chance
ConscientiousnessWith high Conscientiousness, reproducibility outweighs enthusiasm: a false positive scaled to the plant is paid for in lost recovery
Convinces the plant superintendent with a brief memo and data from the circuit itself, rather than lengthy presentations
ExtraversionThe profile's moderate Extraversion performs better through evidence-based influence than meeting-room persuasion
Keeps the daily balance and logging routine without exceptions, even when the circuit is running stably
Structure & RhythmHigh Structure & Rhythm in this range generates continuous data series that allow a deviation to be explained in hours rather than weeks
Sustains a multi-week test campaign with ambiguous results without rushing conclusions to close the matter
Emotional StabilityThis profile's Emotional Stability range tolerates the discomfort of not yet knowing, a necessary condition for not forcing data toward the preferred hypothesis
Requirements and Skills
- Degree in metallurgical engineering, chemical engineering, or process engineering
- Experience in a concentrator plant, hydrometallurgical operation, or metallurgical laboratory
- Command of mass balances, statistical process control, and design of experiments
- Knowledge of mineralogy applied to mineral processing
- Ability to coordinate work with operations, chemical lab, and maintenance
- Availability for shift work or on-site residence at the mine depending on the operation

Illustrative Example
Rethinking a flotation regime that hadn't changed in years despite ore variability
A concentrator plant uses this profile to select metallurgists who will question established practices when process data justifies it. For example: a metallurgist detects that ore variability from a shift in the mining front is degrading flotation circuit selectivity. Their Openness leads them to propose a redesign of the collector dosing regime that contradicts practice established years earlier. Their Conscientiousness ensures a rigorous pilot test program before presenting results. The approved redesign improves metallurgical recovery on a sustained basis. This pattern illustrates that recovery improvements in mature plants don't come from new technologies: they come from metallurgists willing to question the process's assumptions.
