Greenfield
Initial State
- • New mining project with low grade of mineral copper
- • USD $3.9 billion initial investment, 110.000 tpd expected production
- • Innovative design is required to optimize the business case
- • Management is willing to apply Flow Partners’ LEAN MINING® program from the beginning and a balanced approach of people, process and technology
Improvement Opportunities
- • Pre-stripping mine operation, executes value stream analysis for 2 years
- • Improvement opportunities identification to increase productivity in hauling and loading
- • In plant construction, value stream analysis is applied to assess the expected performance (as Greenfield)
- • Rock size reduction to primary crusher needed to ensure optimal recovery
- • Plant operation orientation towards variability reduction more than throughput maximization, since performance depends on fine moly copper grade, highly sensitive to variability
What we did?
- • Multidisciplinary team configuration, also with participation of other sites to design and execute based on Flow Partners’ LEAN MINING® program
- • Crossed KPI´s definition for processes performance control
- • Technology Strategy development towards business integration, from mine to final product
- • 2 ownership changes cause inconsistencies in vision application
Results
- • Trucks load factor over 90% to fulfill plant demand
- • Time and variability reduction in shift turns
- • Availability increase for loading and hauling equipment
- • Utilization increase for loading fleet
