Ore Tracking RFID Tagging Specification (DWG)

Ore tracking via RFID enables end-to-end material accountability from extraction through crushing, blending, leaching, smelting, and refining—critical for grade control, regulatory compliance (e.g., Dodd-Frank conflict minerals reporting), and operational optimization. The specification establishes standardized tag form factors (e.g., ruggedized ceramic-encapsulated passive UHF tags rated IP68/NEMA 4X), mounting methodologies (e.g., embedded in blast-hole collars, affixed to haul truck buckets or conveyor chutes), and data schema (e.g., EPCglobal-compliant TID/EPC memory banks storing unique ore ID, timestamp, origin block, assay batch ID, and metallurgical priority code). It mandates interoperability with existing mine automation systems (e.g., OSIsoft PI, Siemens PCS7, or ABB Ability™) via OPC UA or MQTT gateways, ensuring real-time synchronization with MES and LIMS databases. Environmental constraints—including temperature extremes (-40°C to +85°C), vibration spectra per ISO 5344, and electromagnetic interference mitigation near high-power drives—are codified to guarantee reliable read performance (>99.5% success rate at 3–5 m range under typical plant conditions). Validation procedures, including tag survivability testing (drop, abrasion, chemical exposure) and system-level read/write throughput benchmarks, are also defined to ensure robustness across the metallurgical value chain.
