D80 vs Primary Crusher Throughput at Aguablanca Nickel Mine (Aden Muñoz et al)
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 Corporates Culture.
General Manager Operations Manager (Earth Moving) Load & Haul Ancillary (Owner or Contractor) Maintenance - Mechanical - Electrical Fragmentation Manager Fragmentation Superintendent - D & B - Crushing & Grinding Technical Dept. Production Planning, Grade Control Process Manager (Mineral concentration) Operations - Flotation or LX/SX/EW - Tailings - Ancillary (water, etc.) Maintenance - Mechanical. - Electrical & Instrumentation
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 A key area to achieve Corporate goals.
