Metallurgist, Process Optimization
JobsBy First Quantum Mineral
:\r\n\r\nThe Metallurgist will provide specialist technical support for gravity gold recovery optimization, metallurgical test work, and plant performance improvement. The role will focus on maximizing gravity recovery, reducing gold losses, and identifying sustainable opportunities to improve overall plant performance. The role also requires significant data analytic focus.\r\n\r\n \r\n\r\nKey Responsibilities:\r\n\r\n \r\n\r\n \tAnalyse plant data and metallurgical performance trends to identify gold recovery gaps and improvement opportunities.\r\n \tMonitor and optimize gravity recovery systems, including Knelson and Falcon centrifugal concentrators.\r\n \tConduct plant surveys, sampling campaigns, metallurgical balances, and gold-loss investigations.\r\n \tPlan, conduct, and interpret GRG and E-GRG test work using the laboratory-scale Knelson concentrator.\r\n \tEvaluate the impact of ore type, grind size, classification efficiency, circulating load, and gold liberation on gravity recovery.\r\n \tOptimize concentrator operating parameters, including feed rate, feed density, fluidization water, cycle duration, bowl speed, and concentrate mass pull.\r\n \tCompare theoretical gravity-recovery potential with actual plant performance and develop actions to close identified gaps.\r\n \tEstablish representative sampling methods, sampling frequencies, and quality-control requirements.\r\n \tCoordinate gold assays, screen-fire assays, particle-size analysis, and mineralogical investigations.\r\n \tTroubleshoot plant and laboratory performance issues using metallurgical data and structured root-cause analysis.\r\n \tIdentify, evaluate, and implement technical projects to improve gold recovery, plant efficiency, and operating costs.\r\n \tPrepare technical reports covering surveys, test work, plant trials, findings, and recommendations.\r\n \tProvide technical support to Operations, Laboratory, Maintenance, and Engineering teams.\r\n \tTrain and guide operators, technician
