What this role is
Serves as the senior technical authority for ore crushing, grinding, and metal extraction operations across a processing plant. At the Principal Support Specialist (S5) level, the role owns function-wide support practice, program-level and systemic support problems, and drives support strategy across the function. Subject-matter authority; shapes the practice.
What this level does
- Serve as the plant's most skilled operator, resolving complex circuit problems that others cannot and acting as the working lead/facilitator across the full processing flow during difficult or unprecedented runs.
- Contribute to the creation and refinement of standard operating procedures, start-up/shut-down sequences and risk assessments, drawing on deep circuit knowledge to improve methods.
- Analyze operating data and sampling results against circuit targets to recommend optimization changes, and partner with process engineers to trial and embed new operating techniques on the plant.
- Provide structured guidance, on-the-job coaching and competence sign-off to operators across levels, influencing how the shift team runs the plant.
- Knowledge applied
- Highly skilled specialist across the full processing flow; contributes to the creation of operating procedures, sequences and risk assessments within the plant.
- Complexity & problem solving
- Resolves the most complex circuit problems and develops improved operating techniques, often in partnership with process engineers.
- Collaboration & interaction
- Acts as working lead/facilitator; provides coaching and competence sign-off and influences how the shift team operates.
- Typical experience
- 6+ years; expert operator recognized as the plant's operating authority.
Skills at this level
- Stationary Processing Plant Operation
- — Sets up and operates plant and machinery that grind, crush, cut, saw and slice rock, minerals and stone to job specifications, and maintains steady feed of unprocessed material from conveyors into the machines.
- Circuit Monitoring and Control
- — Observes meters, gauges and control panels and adjusts valves and controls to keep crushing, screening, milling, thickening, leaching, CIL and gold-recovery circuits running safely and efficiently.
- Mineral Separation and Recovery
- — Separates metal and mineral concentrates from ore and alluvial deposits using thickening, flotation, gravity separation, filtration, and magnetic or electrostatic separation.
- Processing Chemistry Knowledge
- — Applies knowledge of leaching, flotation, gravity separation and related chemical processes involved in pre-treatment and demineralization, and uses it to make changes that optimize plant performance and efficiency.
- Quality Sampling and Inspection
- — Examines processed material visually and by hand against standards, collects representative samples for laboratory testing, and records processing quantities, types and dimensions during the shift.
- Malfunction Detection and Maintenance Support
- — Detects abnormal noise, vibration, flow or readings that signal a plant malfunction, and assists with preventative and corrective maintenance and repair of plant and machinery.
- Preventative Maintenance and Housekeeping
- — Carries out routine preventative maintenance inspections and housekeeping of processing equipment and reports plant defects for repair.
- Process Optimization Adjustment
- — Makes appropriate changes across plant processes and circuits to improve throughput, recovery and efficiency, accounting for downstream effects of each adjustment.
- Safety, Environmental and Regulatory Compliance
- — Conducts risk assessments and works within environmental regulations and the safety rules governing mineral-processing plant operation.
- Shift Record Keeping
- — Records processing information such as quantities, types, dimensions and circuit readings on shift logs to document plant operation and support quality control.
- Working Lead on Shift
- — Guides less experienced operators, allocates equipment coverage, and leads safe start-up, shut-down and isolation of the plant during a shift without formal people-management authority.
- Operating Procedure Development
- — Contributes to the creation and refinement of standard operating procedures, start-up/shut-down sequences and risk assessments, and coaches operators to the new methods within the plant.
- Regulated Operator Qualification
- — Holds and maintains required mineral-processing plant operating qualifications (e.g. the MPQC Level 2 Diploma in Mineral Products Mobile Plant Operations with underpinning English and maths) where the pathway is regulated.
