  6. CurrentArrangement

  7. Current Arrangement Industrial Psychology of Mine and Mill Managers • Same company… but different goals. • Different approaches… but same ore! A Game of Thrones…

  8. CurrentArrangement Mine Department • Mining Engineer • Drilling and Blasting • Loading and Hauling • Ancillary Services • Mine Maintenance • Mine Planning

  9. CurrentArrangement Mill Department • Metallurgical, Chemical or Industrial Engineer • Crushing • Grinding • Ancillary Services • Mill Maintenance • Flotation – LX - SX/EW. • Tailings management.

  10. Mine vs Mill Manager

  11. Mine Manager • “I have accomplished my tonnage goals” • “I have to look after MY costs and MY budget” • “Since I cannot cut on fuel costs, I will cut on explosives costs”

  12. Mill Manager • “The grade you sent is lower than declared” • “You are sending boulders that plug my crusher” • “My steel and kwt/h costs are high and throughput is low ”

  13. CEO “You supply your planned tonnes & grade” “You give me the monthly metal production” “And do not forget: keep your costs low, guys…!”

  14. Riotinto mine (5.000 years)

  15. A story of two cities…

  16. Fragmentation & Thevaluechain Energy as a project key driver.

  17. Fragmentation & The value chain Energy consumption.

  18. Fragmentation & The value chain Energy costs.

  19. Case study CoarseFragmentationonhard rock mine

  20. Case study D80 vs PrimaryCrusherThroughput at Aguablanca Nickel Mine (Aden Muñoz et al)

  21. Opportunities A well managed fragmentation process has significant overall cost-saving potential: • Increasing resource recovery. • Reducing dilution (increase the grade delivered to the mill). • Reducing power consumption at the mill. • Increasing mill throughput. • Reducing metal losses (fines). • Increasing OEE at the crushing plant. This new approach should be incorporated to the Corporate’s Culture.

  22. Fragmentation Department A key area to achieve Corporate goals. Objectives: • To reduce the size of the ore from a bulk in situ mass to fit the bottleneck at the mill. • To manage efficiently the overall fragmentation of ore: • As a single process • Under the same budget • Under the same management from the Mine to the Process Plant (flotation, LX or others). • To increase the valuable metal recovery
