● Operating production machines (conveyor, burner, slag cooler, O₂ blower) in strict compliance with Standard Operating Procedure (SOP) to ensure efficient pyrite ore roasting process. ● Conduct daily equipment inspections to identify potential malfunctions or operational parameter deviations. ● Monitor real-time production flow in control room and adjust parameters (temperature, fuel flow (pyrite ore), pressure, gas flow) to maintain optimal calcine quality ● Operated and controlled calcine storage levels in the pneumatic conveying system, ensuring smooth transfer processes in compliance with operational procedures. ● Perform bi-hourly sampling of waste products (calcine) and document analysis results for continuous quality evaluation. ● Performed start-up preparations in accordance with Standard Operating Procedure (SOP) , including equipment inspection, control system checks, and initial parameter verification ● Followed planned or emergency shutdown procedures, including system cooling, feed cutoff, and equipment safety securing. ● Coordinate with maintenance and production teams to minimize downtime while maintaining 5S workplace standards.

• Studying the Sulfuric Acid Production Process from Pyrite Ore (FeS₂) Gained in-depth knowledge of the industrial process stages, from pyrite roasting to the conversion and absorption phases in sulfuric acid production. • Learning About Potential Hazards and Emergency Handling in a Sulfuric Acid Plant Identified various occupational safety risks, including exposure to hazardous gases and corrosive substances, and understood emergency response procedures in compliance with safety standards. • Participating in Technical Discussions with Fellow Trainees Collaborated and exchanged insights with other trainees to deepen understanding of the production process and operational challenges. • Familiarizing with the Functions of Sulfuric Acid Plant Equipment Studied the types, functions, and working principles of key equipment such as burners, converters, absorbers, pumps, and process control systems.

• Conducted aseptic sampling and preparation of raw materials (seaweed, water, waste, chemicals) to prevent contamination • Analyzed seaweed quality parameters (moisture, ash, sediment) and water characteristics (pH, conductivity, Fe, Mn, COD) using standard lab equipment • Verified production chemical concentrations through titration and spectrophotometry to ensure technical specification compliance • Performed regular boiler water testing (total hardness, pH) to prevent scaling and equipment damage • Prepared detailed test reports for division head review and process improvement recommendations
