Reports To: Mine Operations Manager

Aggregate Mineral Resource Group, LLC (AMRG) is seeking an experienced, technically skilled, and highly organized Iron & Mineral Processing Laboratory Manager to lead and coordinate laboratory operations supporting the company’s iron recovery, mineral processing, metallurgical, resource recovery, and analytical operations. AMRG operates and is developing multiple specialized laboratory functions supporting its mineral and resource-processing activities. Depending on operational requirements and the successful candidate’s technical background, this position may oversee one specialized laboratory, a combination of laboratory functions, or multiple interconnected testing and process-control activities.

Laboratory activities may include iron-bearing material characterization, metallurgy, mineral processing, mineral separation, beneficiation, wet chemistry, acid-based testing, sample preparation, analytical testing, process recovery testing, flotation, and related laboratory functions. The manager is accountable for personnel, workflow, testing schedules, sample control, equipment, calibration, QA/QC, safety, documentation, reporting, and coordination with AMRG operations. The successful candidate does not need to personally perform every specialized analytical method but must possess the technical foundation and laboratory-management experience necessary to oversee qualified personnel, maintain analytical integrity, establish standardized procedures, and ensure work is completed safely, accurately, efficiently, and on schedule.

This is not a biotech or pharmaceutical laboratory role.

• Lead daily operations for assigned iron, metallurgical, mineral-processing, process-control, and analytical laboratory functions.
• Coordinate laboratory priorities, staffing, workflow, testing schedules, turnaround times, equipment utilization, and resource requirements based on production and project demand.
• Supervise laboratory technicians and coordinate work with metallurgists, mineralogists, engineers, consultants, vendors, and operations personnel.
• Develop scalable laboratory systems, SOPs, training programs, quality controls, and reporting practices as AMRG expands its internal testing capabilities.
• Oversee collection, receipt, identification, tracking, storage, preparation, and distribution of ore, feed, concentrate, tailings, intermediate, and finished-material samples.
• Establish standardized sample-preparation procedures including drying, crushing, splitting, grinding, pulverizing, sieving, and other applicable methods while controlling contamination and maintaining representative samples.
• Oversee or coordinate metallurgical and mineral-processing testing involving beneficiation, concentration, separation, flotation, recovery, and process optimization.
• Evaluate laboratory results related to iron-bearing material characteristics, feed quality, concentrates, tailings, recovery performance, and processing conditions.
• Oversee or coordinate wet-chemistry and acid-based procedures used for mineral characterization, metals analysis, process control, and resource-recovery work.
• Ensure acids, reagents, standards, and laboratory chemicals are properly prepared, labeled, stored, handled, documented, and disposed of in accordance with safety requirements.
• Coordinate specialized instrumental or analytical testing and external laboratory services when testing exceeds current in-house capability.
