Process Engineer - Mineral Processing Location: Gauteng Position Type: Permanent About the Role We are seeking an experienced Process Engineer to lead front-end design, simulation, test work, and commissioning for comminution and mineral separation projects. You will turn test data and simulations into practical, commercially sound process solutions while supporting client site audits, sales technical support, and plant optimizations. Key Responsibilities Front-End Engineering: Develop concept-to-feasibility-level process flowsheets, PFDs, mass/water balances, and equipment sizing across comminution and mineral separation circuits. Process Simulation: Build, calibrate, and maintain Aggflow models (and related packages) using plant and test data to run scenario/sensitivity analyses. Test Work & Pilot Guidance: Specify and guide test work programs, interpret metallurgical results, and translate findings into clear design recommendations. Site Audits & Optimization: Conduct on-site plant audits, sampling surveys, and mass balance reconciliations to identify operational bottlenecks and efficiency gains. Commissioning & Sales Support: Provide technical input for proposals, support cold/hot commissioning on site, and execute performance guarantee testing. Key Requirements Education: BEng / BSc degree in Chemical, Metallurgical, or Mineral Process Engineering (or equivalent). Experience: Minimum 5 years in mineral processing engineering, specifically in front-end / study-phase design. Technical Expertise: Hands-on experience with flowsheet development, mass balancing, and equipment sizing. Software: Proficiency with Aggflow or comparable process simulation software (e.g., JKSimMet, Bruno, METSIM, LIMN). Site Travel: Willingness to travel to client sites and stay away from home for multiple days at a time. Advantageous: ECSA registration (Pr Eng / Pr Tech Eng) and direct plant commissioning/auditing experience.
