Reviewed daily process performance with operators and production superintendents in 3 unit operations. Ensured environmental constraints were respected and ensured process remained within safe operating regime.• Implemented batch-based statistical monitoring software to optimize batch-based process. Combined Pareto analysis with operator coaching, reducing off-grade production from 45% to 15%. • Prevented zinc oxide losses and decreased environmental exposure by standardizing leaching… Show more Reviewed daily process performance with operators and production superintendents in 3 unit operations. Ensured environmental constraints were respected and ensured process remained within safe operating regime.• Implemented batch-based statistical monitoring software to optimize batch-based process. Combined Pareto analysis with operator coaching, reducing off-grade production from 45% to 15%. • Prevented zinc oxide losses and decreased environmental exposure by standardizing leaching parameters and procedures (reducing deviations). Rolled out operator training, and provided supporting documentation.• Utilized root cause analysis to address significant safety concern. Implemented vented splash guard, decreasing tap times and increasing slag throughput by 3%. • Commissioned process equipment, writing procedures, verifying completion of employee training prior to hand-off, and establishing troubleshooting criteria for normal use.

Evaluated technical feasibility of 6 projects and issued recommendations for proceeding / ceasing further development work. • Started and managed capital project ($250K), from initial concept through approval process, design, and commissioning.

Evaluated refractory lifespan under different alloying regimes.• Collected and analyzed data for Senior Metallurgist, ensuring sufficient refractory inventory for completing test work.• Proposed 250k$ per year cost reduction strategy, with 6-month payback, by adjusting sensitivity of existing load cells.

Evaluated effect of using MillPebs grinding media on metals recovery and power draw.• Designed and performed floatation cell test campaigns and analyzed data. Issued costs / benefits report demonstrating costs outweighed benefits, recommended not to proceed with full-scale implementation.

Evaluated technical feasibility of 6 projects and issued recommendations• Lead a minor capital project from initial concept through the approval process, design and commissioning
