Cobre Mining Company
Continental Mine Project
This SION project was in two phases: Phase 1 refurbished the existing mill equipment (which had been down for ten years) for start-up; Phase 2 consisted of Engineering, Procurement, and Construction Management and supply to enhance the existing equipment to bring the mill from 5000 TPD to 7500 TPD. The original circuit consisted of a jaw crusher, SAG mill, Pebble Mill, Classification, Flotation, and Filtration. SION upgraded the Classification, added to the flotation, installed a 5-1/2’ Short Head Cone Crusher along with Associated Conveyors and Structures (this Crusher broke the recirculation fraction). SION supplied a complete Surface Loadout Facility for the underground ore.
