• Crushing Circuit Optimization: Monitor and adjust crusher gaps, conduct regular Met checks, and optimize crusher performance to meet daily, weekly, and monthly targets. • Performance Monitoring & Reporting: Track and report crushing, milling, and classification KPIs; compile daily, weekly, and monthly performance summaries • Routine Plant Inspections: Perform scheduled inspections and spot checks on crushers, mills, classifiers, weightometers, and screens to ensure operational integrity. • Particle Size & Plant Surveys: Conduct monthly belt cuts and full plant surveys for physical PSD analysis across circuits to support process optimization. • PSA Camera: Calibrate and monitor PSA cameras for real-time particle size analysis, ensuring functionality and data reliability. • Continuous Improvement: Identify bottlenecks, evaluate operating parameters, and drive long-term improvement initiatives across comminution circuits. • Technical Operational Support: Work closely with operations teams to troubleshoot and optimize daily performance; actively participate morning planning meetings. • Grinding Media: Maintain target ball load levels, track ball consumption, oversee ball sorting operations, and ensure proper charging protocols. • Classification: Monitor cyclone and screen operation, conduct regular inspections and PSD checks, and ensure target classification is achieved. • Mill Liner: Lead liner wear monitoring using tools like FARO 3D scanners, and report on liner performance. • Documentation & Communication: Maintain accurate records and generate comprehensive reports and updates for operational and metallurgical teams. • Cross-Department Coordination: Collaborate with, engineering, warehouse, and procurement teams to support seamless operations and planning

• Audited the ingress of foreign material into the cyclone circuit leading to premature failure of ceramics in cyclones • Spearheaded the closing of opportunities identified in the audit and ensured that all engineering controls are implemented to the required standard • Reviewed optional use of linatex rubber (R35) and currently on trial to minimize and reduce cost during optimization period • Conducted performance review of critical cyclone parameter via plant sampling and Pi historical data and recommended optimized range of operations • Conducted circuit surveys; belt cuts, sample preparation and screening for PSD analysis.

• Determine and maintain the SCAW metallurgical accounting standards. Conduct daily routine plant checks to capture the work in progress(WIP), buildup of reworks, rejections and the quality of products produced for plant perfomance reports. Collaborate with process control team in ensuring close monitoring of process parameters to reduce build up of reworks and offcuts by doing so reducing on material losses. Collaborate with production supervisors for efficient data capture and storage of production consumables. Ensure Mass Balances, scales and digital tally counters are callibrated periodically to reduce on variances. • Generate daily production and cost optimisation reports, material and scrap consuption reports, daily sales report, additional reports and statistics that may be required by management. • Organise reconciliation between despatching plants and receiving plants, carry out end of month and end of year stock takes. Monitor all hired machinery & services from contractors and process documentation for financial analysis

• Monitored and supervised the metallurgical operations of the plant. • Monitored process performance and conformity of products. • Resolved all technical queries from internal and external customers. • Spearheaded and cultivate team work among all sectional teams. * Spearheaded the implementation of the culture of continual improvement in area of responsibility * Spearheaded the implementation of ISO 9001:2015 * Carried out metallurgical investigations on operating parameters, products, processes, preparation and presented technical reports to relevant officials

• Maintained proper operations of pumps and compressors by inspecting components and addressing faults. • Calculated gas ratios to detect deviations from specifications using testing apparatus, observing temperature, pressure level and flow gauges. • Supervised and controlled the storage and distribution of Industrial Gas to SCAW’s customers • Prepared quotations, Issued and collected gas cylinders from customers; • Monitored gas cylinders’ movements through the cylinder tracking system. • Led the transition to a paperless practice by implementing a more accurate, faster and safe way of capturing cylinder serial numbers using a bar code scanner; reduced on time wastage • Ensured safe usage of gas and other equipment as per ISO standard. My Achievements in this role are available upon request.

• Carefully reviewed daily work orders to maintain accuracy, reduce material waste and increase overall productivity. • Collaborated with operators to ensure targets were met. • Optimized furnace parameters. • blended Manganese ores and charged the electric furnace in batches • Monitored Electrodes; Case reading and calculated the paste level. • Supervised the charging the furnace with coal, Various manganese ores, dolomite, charcoal and quartz. • Controlling of the feed conveyor belts and vibrating feeders using the Automatic Batching System machine and an Electric Arc Furnace (EAF). • Monitoring of assays for each tapping. • Ensuring a three times tapping cycle is maintained in a particular shift. • Monitoring of carbon paste level and paste baking for each electrode. • Making material correction to the furnace charge in case of the metal product grade deviation to that required by the customers. • Electric load regulation of the furnace and monitoring the hourly and daily furnace performance to ensure optimum smelting conditions. • Complete root cause analysis and corrective action planning on Manganese, Dolomite, Coal and Quartz materials failures. • Matte and Slag separation supervision. • Prioritized and organised tasks to accomplish operation goals. • Characterize physical and chemical properties of starting materials, intermediate reactions and final products. • Coordinate project plans to execute major upgrades and successfully guide technical teams in achieving project goals. • Write engineering reports, including manufacturing processes, equipment specifications and change notices and implement modifications. • Demonstrate leadership by making improvements to work processes and helping to train others. My Achivements in this role are available upon request.
