Engineer 3 Metallurgy at Geita Gold Mine Tanzania

OBJECTIVE OF THE ROLE

Manage the metallurgical and technical activities of an assigned section of the process plant, provide technical assistance to production and maintenance teams, drive continuous improvement projects, and ensure the section contributes to overall plant recovery, throughput and efficiency. Provide technical support across the broader flowsheet, identify gaps and optimisation opportunities beyond the immediate section where required, report directly to the Superintendent 2 – Process Technical, and deputize for the Superintendent-2 as needed.

ROLE ACCOUNTABILITIES

Technical- Core (applies to all Senior Metallurgist positions)

• Provide discipline-specific technical support within the assigned section for the purpose of optimizing plant performance and resource recovery
• Analyze process and ore characteristics data, and their impact on recovery, throughput, and operating costs
• Proactively identify processing inefficiencies and develop optimization opportunities through structured test work programmes
• Develop, implement and maintain standard operating procedures and control philosophies for the section
• Lead or participate in root cause analysis (RCA/ICAM) and corrective action plans (CAP/CAPA) for process deviations, incidents and non-conformances
• Coordinate with cross-functional teams (mining, geology, maintenance, laboratory, other process sections) to align findings with plant operations
• Prepare accurate technical reports, KPI trend analyses, project updates, and presentations for senior management and stakeholders
• Support annual budgeting and cost control for the section, including reagents, consumables, energy and maintenance inputs
• Ensure data integrity, accuracy and timeliness of process, metallurgical and reconciliation reporting
• Must have relevant and adequate technical skills on comminution and hydrometallurgy of gold (crushing, milling, CIL) and be capable of performing plant performance analysis and identifying gaps across the entire flowsheet
• Must have the relevant and adequate technical skills on the communition and hydrometallurgy of gold i.e. crushing, milling, carbon in leach (must be capable of performing plant performance analysis, identify gaps and optimization initiatives across the entire flowsheet)
• Prepare technical reports, project updates, and presentations for senior management and stakeholders.

• Investigate, explain and resolve reconciliation variances and metallurgical accounting discrepancies, including statistical bias detection and uncertainty analysis

E. Metallurgical Laboratory

• Manage laboratory activities including sample preparation, fire assay and metallurgical test work
• Ensure the accuracy and reliability of laboratory test results and drive continuous improvement of laboratory processes
• Maintain the QAQC programme (standards, blanks, duplicates, control charts) and equipment calibration
• Support geometallurgical and plant optimization test work requirements

F. Geometallurgy

• Develop and implement geometallurgical models to support process optimization and resource/mine planning
• Collaborate with geology and mining teams to integrate geometallurgical insights into mine planning
• Analyze ore characteristics (mineralogy, hardness, deleterious elements) and their impact on recovery, throughput and operating costs
• Lead future test-work programmes aimed at beneficiation of refractory ores and reagent optimization

G. Water Treatment & Environmental

• Supervise water treatment plant operations, ensuring compliance with NEMC and other environmental regulations
• Identify and implement best practice to improve water quality and treatment efficiency
• Monitor and analyze water treatment data (including tailings water balance and discharge quality) to enhance plant performance

Schedule

• Operate on the site's standard shift/roster pattern and participate in on-call/standby arrangements as required by the section
• Participate in shutdown planning, execution and post-shutdown review for the section
• Comply with the company's code of conduct, safety and environmental management systems at all times
• Coordinate with HSEC teams to ensure environmental permit conditions and reporting obligations are met

Other Duties

• Compilation of the ABU Weekly Report, month end statistics and Process production reports.
