Responsibilities

Collect ore, concentrate, and tailings samples from mine sites and processing plants.
Prepare samples through crushing, splitting, grinding, and sieving to ensure uniform and representative analysis.
Safely handle and transport large/heavy samples (50–60 lbs) in compliance with safety standards.
Perform ore grade analysis for iron, gold, and rare earth elements using wet chemistry, fire assay, and instrumental methods.
Conduct froth flotation testing to evaluate reagent performance, recovery efficiency, and concentrate quality.
Execute aggregate gradation and physical property tests to meet plant specifications.
Measure moisture content, density, and mineral composition for operational reporting.
Operate, calibrate, and maintain laboratory equipment, including spectrometers, flotation cells, sieves, scales, and moisture analyzers.
Record, analyze, and report test results with precision and accuracy.
Generate daily and weekly laboratory reports for mine operations and plant management.
Identify anomalies, deviations, or efficiency gaps in test data, collaborating with operations teams to drive improvements.
Work with metallurgists, mineralogists, and plant operators to align lab results with production goals.
Provide insights to improve recovery rates, flotation efficiency, and ore quality.
Participate in continuous improvement initiatives related to mineral recovery and tailings management.
Maintain a clean, organized, and compliant laboratory environment.
Follow all MSHA, OSHA, and environmental regulations regarding laboratory operations, sample handling, and waste disposal.
Actively participate in safety training and reporting.
