Job Purpose To execute and supervise all mechanical engineering, installation, and integration activities for the PMR section of Smelter 5, including equipment used for decanting, filtration, leaching, electrowinning, refining, and bullion handling, ensuring compliance with approved designs, safety norms, and project schedules. The role is responsible for translating mechanical deliverables into reliable, safe, and operable systems by coordinating with process teams, EPCM, vendors, and site contractors to enable smooth commissioning and optimized recovery of precious metals (Au, Ag, PGMs). - Mechanical Engineering Implementation for PMR Processes - Implement approved mechanical layouts, GA drawings, piping designs, and equipment installation schematics for PMR process areas covering decanting, filtration, leaching, electrowinning, refining, and bullion handling. - Validate mechanical interfaces with PMR process PFDs and P&IDs to ensure correct flow paths, retention times, and containment of high?value streams. - Ensure mechanical execution supports both batch and continuous PMR process steps safely and reliably. - Mechanical Equipment Specification & Vendor Coordination - Support finalization and execution readiness of mechanical equipment specifications for decanters, filter presses, leach reactors, agitators, EW cells, bullion furnaces, dryers, tanks, and associated auxiliaries. - Participate in technical discussions, bid evaluations, vendor clarifications, FATs, and inspection activities for specialized PMR equipment sourced from niche global vendors. - Monitor equipment fabrication progress, material of construction compliance, and readiness for site installation. - Construction & Mechanical Installation Oversight - Supervise mechanical installation activities including reactors, tanks, structural supports, piping systems, agitators, EW cells, furnaces, dryers, and material?handling equipment for PMR facilities. - Ensure correct alignment, leveling, fastening, gasket integrity, and leak?free assembly of equipment handling precious metal?bearing solutions. - Coordinate with civil, electrical, and instrumentation teams to ensure readiness of foundations, utilities, ventilation, and access clearances. - Mechanical Integration with Utilities & Thermal Systems - Ensure integration of mechanical systems with utilities such as compressed air, cooling water, hot water, exhaust systems, and ventilation. - Coordinate refractory linings, insulation systems, and thermal protection for bullion furnaces and dryers in line with approved designs. - Validate mechanical readiness for heat?up, expansion movement, and thermal cycling of PMR high?temperature units. - Commissioning & Operational Readiness - Support mechanical pre?commissioning activities including flushing, pressure testing, rotations, agitation trials, and mechanical completion checks. - Assist commissioning of batch leaching reactors and continuous filtration/electrowinning systems running in parallel. - Support trial runs and ramp?up activities to ensure stable, leakage?free, and reliable mechanical performance during precious metal recovery trials. - Safety & Environmental Compliance (Mechanical Scope) - Implement mechanical safety procedures for handling toxic chemicals, high?value materials, confined spaces, lifting operations, and rotating equipment. - Ensure mechanical systems related to effluent containment, scrubbers, gas absorbers, and spill control meet environmental and safety norms. - Participate in HAZOPs, risk assessments, safety audits, and incident?prevention initiatives for PMR areas. - Interface & Coordination - Coordinate mechanical interfaces with upstream units (Refinery, Anode Slime Treatment) to ensure smooth transfer and containment of intermediate products. - Ensure seamless mechanical integration with downstream bullion handling, security, and material transfer systems. - Resolve execution?level interface issues impacting PMR continuity or metal accountability. - Schedule, Cost & Contractor Control - Track mechanical execution progress against PMR project schedules and commissioning milestones. - Monitor contractor performance, installed quantities, and compliance with BOQs and specifications. - Support identification of value?engineering or constructability improvements without compromising safety or recovery efficiency. - Reporting & Documentation - Compile mechanical QA/QC records, commissioning checklists, punch?list closures, equipment dossiers, and as?built drawings. - Ensure vendor manuals, maintenance instructions, and spare lists are complete and handed over to O&M teams. - Support joint inspections and smooth mechanical handover post?commissioning.
